Omega marine patent 146310 with slide out case made of Staybrite steelThis is a narrow study of the Omega Seamaster 300 watch from the period 1963/64 – 1969. An examination of this model shows there are huge variations sometimes as many as 3 a year over the 6 year period.The Author welcomes any observations which assist in the clarification for collectors. There will be a website on the earlier Seamaster 300 the CK2913 (1957 – 62) but given the complexities, splitting the history in this way serves the collector better.In 1932 the world was introduced to the Omega Marine (as seen on the right), which was Omega’s first real divers watch and the expertise and designs from that watch were carried forward to create the first Omega Seamaster 300.The original Seamaster line commenced in 1948 and this watch was originally supplied to RAF crews as a military aviator. In 1954 they were sent to SLWR for testing where they were found to be water resistant to 60 metres and temperature resistant between -40 to +50 degrees centigrade.The introduction of the revolutionary O-ring gave these watches a ruggedness, a waterproofness and a precision which was superior to all other brands at that time. In 1957 the world was greeted by the arrival of Omega’s famous trilogy: Speedmaster, Railmaster and importantly the Seamaster 300.The Seamaster 300 was guaranteed to 200m although tests equivalent to 300m have been carried out without water ingress, hence the rear of the watch carried the title ‘certified high pressure waterproof Seamaster’. This watch was designated the CK2913 which was replaced in 1950 by CK14.755 (calibre 552) which then became ST165.014 in 1962 thereafter ST165.024 in 1963-64The watch using a crown and dial variation complied with the Ministry of Defence DEF STAN 66 guidelines and was issued to all sectors of the British Army however again this would be the subject of a subsidiary site. There is substantial mythology surrounding the watches worn by the divers for Comex (compagnie maritime d’expertises).
This was a company founded in 1961 by Henry Delauze and it pioneered very deep saturation diving starting with Hydra 1 in 1968.Uniquely Omega was the exclusive supplier for watches in all deep sea diving tests because they were the only company at the time that could guarantee hermetically sealed watches. Later on in 1971-72 onwards companies such as Rolex tried to enter this market by introducing a helium release valve because their watches were not impermeable, however this was a very poor solution because helium inside a watch, even if released on decompression, causes fluctuation in the watches time keeping ability. Rolex were also faulted for their diving watches did not have sufficient legibility underwater nor did they introduce a sapphire scratch-proof crystal until 11 years after Omega.At the outset in 1967 various manufacturers submitted watches for testing to COMEX but none matched Omega’s waterproofness ruggedness and precision. And the watch of choice for early exploration and testing was the Seamaster 300. Unfortunately amongst the collecting community there is a tremendous amount of misinformation about Comex Omega and subsequently Comex Rolex.The Author is currently compiling what he hopes will be a more authoritative work on this topic. In the meantime this is a valuable opportunity to disabuse the belief that Omega only ever supplied eleven watches to Comex and in this regard I have included the invoice from Comex at the early start of their cooperation (see image on left).
As can be seen 34 watches were supplied. The first 30 being 166.024 Seamaster 300s in 565 calibre and the last 4 being extremely special Seamaster 1000s in 552 calibre.
It is worthy of note that the Seamster 1000 Proplof preceded the Seamaster 600 Ploprof which at this stage was merely an MVP.This is just a sample of the Seamaster 300s sent to Comex in addition there were a considerable number of Seamaster 1000s and Seamaster 600s supplied. Theses were all highly engineered professional tool watches on which divers’ lives depended they were not a dress watch which someone stuck a bezel on for marketing purposes.
Any collector who has a watch which they suspect is part of this cohort should contact the Author for authentication. 1035-1501-16A rare bracelet, produced for a single quarter in 1966. Identical to the 1035 except for the stamp on the clasp.1035-16/516Ran from 1966 – 1972, usually seen with the 516 end link. No picture required as it is identical to the 1039 expect for the inner stamp.StrapsIn addition to the bracelets there was available a tropic rubber strap as seen below.As well as the rubber strap Omega offered a ‘corfam’ waterproof leather version, with a stainless buckle along the style of an ISOfrane strap. CrownFrom he beginning of the watch’s production until 1968 the crown was of the naiad type with 24 teeth and 6.8mm in diameter, thereafter. The naiad crown has in its centre a 3 pointed star, which is hypothesised as representing the 3 protections against magnetism, moisture and pressure. The word ‘naiad’ originate from Greek mythology; the Naiads are a type of female spirit, or nymph, presiding over fountains, wells, springs, streams, brooks and other bodies of fresh water.
As a consequence of the work being carried in deep sea diving testing Omega introduced a screw-down crown which was 6.4mm in diameter with 22 teeth. This new hermetical sealing improved the watches depth rating considerably and was ultimately the standard issue for all watches. Please see below the watches work order transition between the naiad crown to a screw-down crown (1967-69). Partway through the production of the watch Omega diverted the case manufacturing to Fabrique la Centrale SA Bienne and there was also a steel supplier changeover from Acier Staybrite to Acier Inoxydable, probably for cost reasons. Staybrite is a chromium-nickel steel and its a trademark that has been around since the beginning of corrosion resistant stainless steel.
It was developed extensively in the 1960s and is the only patented Swiss stainless steel to be used in the watch industry because of its excellent polishing properties and its high corrosion resistance. The brand name has belonged to Firth AG since 1954.Read more about ‘‘ (PDF). Dials1966-67 a dial design change took place and the large triangle was introduced along with the sword hands. Pinholes in the triangle and at the 6 o’clock position appear to be present in many dials as this was the place where the dials were held during the process of the application of lume.4 types: big triangle, small triangle, white writing, gold writing, with date, without date.Please note the author has observed date wheel variations with black text on a white background and white text on a black background. The History of the MovementClick on the images below to see an enlarged detailed view. Please find below the actual registered designs of the watches held on microfiche in addition to internal Omega production documents identifying the watches specification and configuration prior to retail sale. Model Ck 14755This used a 550 or a 552 calibre movement Model Ck 165.014This used the 552 or the 560 calibre movement Model Ck 165.024This used the 552 calibre movement.
Model Ck 166.024This used the 565 calibre movement. Model Ck 166.034This is very rare photograph of a potential prototype with both day and date. MovementIn 1955 Omega bought a small watch factory owned by and called Marc Favre, who had created an automatic calibre using a full rotor. In 1958 they produced the 552 calibre movement which was both shock absorbing and anti-magnetic with 24 jewels. 562 was the same watch but with a calendar function. The 565 (1965) came with a calendar function but also with rapid date corrector.
The calibre 563 (1965) was produced for the American market and featured a calendar function but reduced to 17 jewels. The Calibre 560 was also for the American market; this was a 552 calibre reduced to 17 jewels (see below).

552 calibre (1958)562 calibre565 calibre (1965)The United States in 1922 decided to introduce the Fordney-McCumber Tariff act requiring watches from Switzerland to be subjected to higher levels of import tax. Thus an unadjusted movement was taxed at $2.75 and an adjusted movement to 5 positions taxed at $6.50. In addition the tariff for ruby-bearing watches was $1.25 for 17 jewels thereafter $3 for 24 jewels. Omega responded to this impost by degrading the movement by replacing 7 jewels with metal bearings and coming in under the fiscal barrier. Movement Serial NumbersThis is by no means comprehensive however this may be used as a guideline. It is quite common in the Seamaster 300 range for entire movements to be swapped out at service rather than do a parts replacement.
So the movement number does not always align with the date of manufacture of the watch. 196320 million196421 million166522 million196623-24 million196725 million196825-28 million196928-30 million.

Sometimes it takes a while for classics to strike a chord with watch-lovers. Just because something is widely lauded as an archetype, or as so historically significant you simply have to care, doesn’t necessarily mean you will. Until it hits you, and then all bets are off. This is what I experienced with the 300m.
As an apprentice who worked on the old 1120-powered range from the ’90s and ’00s for a couple of frustrating years, I had more opportunity than most to see it up close. Try as I did, I just couldn’t forge a connection to it.As I’ve said before on aBlogtoWatch, I suffered a similarly uncertain start to before falling in love with it. And suddenly, during the summer this year following the recent update debuted at Baselworld 2018, I got it.
It hit me bang in the mouth and demanded my attention. Finally, I was converted.
So, when I saw the press shots of the Omega Seamaster Diver 300m in Black Ceramic and Titanium, a dark and exciting new model (stirringly sans date), I was very, very interested.Let’s start with the good. First, the movement is excellent.
I still wake up in cold sweats thinking about wrestling with a stubborn hairspring on an ETA 1120. What Omega has done since I left the company (hopefully, no correlation) is double-down on their status as an in-house manufacturer, and really make use of the technology at their disposal to create movements that are new, beautifully decorated, and a dream to service/assemble.Omega has gifted its watchmakers with a solid, reliable, and very well-made caliber in the 8806. Customers should be enthused by this level of uniqueness from a brand that was, for a couple of decades, lagging well behind the high standards its history deserves.The 8806 is approved by METAS, Omega’s in-house chronometer protocol. It beats at 25,200vph (3.5Hz), and is, therefore, able to offer a power reserve of 55 hours. It is resistant to magnetic fields of up to 15,000 gauss, thanks to the in-house silicon hairspring. The reliability and isochronism of this watch is beyond doubt.
I say this with surety, as it is literally impossible to ‘bend’ or manipulate the hairspring in the traditional manner, due to the material it’s made of. Another thing I like very much is the color scheme. Teaming a black case and bezel insert with a titanium bezel and crown makes for a stealthy combo. The absence of the date window at 6 o’clock also cleans up a dial that can look busy because of the wave pattern. On that note, the execution of the modern wave is sublime.
The background has been etched away, leaving a raised, gloss wave pattern in the ceramic dial, rather than pad-printing the design in a slightly contrasting hue. The Omega Seamaster 300m Diver in Black Ceramic and Titanium also sticks with the redesigned helium valve that is now conical, as opposed to straight-sided.But here are the things I don’t like so much. The update from Baselworld 2018 did very well to keep the diameter at 41mm. This new iteration is a swollen 43.5mm. For me, a man accustomed to wearing some pretty gargantuan watches without a problem found that the 41mm variant managed to command a good degree of wrist presence, despite its relatively small diameter. The 43.5mm measurement puts this more in the wear category of the Planet Ocean. I have a feeling this may annoy those looking for a more discreet timepiece.Secondly, one of the stand-out features of the Omega Seamaster 300m was the price.
Retailing at under $5,000 made it a ridiculous value proposition. The Omega Seamaster 300m Diver in Black Ceramic and Titanium comes in at a hugely inflated $7,500, on the rubber strap.
The rubber strap is beautifully designed. It has a really cool keeper system that prevents that irking floating phenomenon.
However, it is not the bracelet, which is one of the nicest things about this range in general.Certainly, the Omega Seamaster 300m Diver in Black Ceramic and Titanium is a visual feast. Hopefully, it will find an audience that craves the extra size and doesn’t mind paying for it.
Visit for more information. Hey SuperStrapper, thanks for commenting.
You’re right about the press images not featuring a close up of the strap system, but basically the second keeper (the one that might escape the tail end of the strap) has a little nipple on its underside, so it can hook on to one of the holes in the strap nearer the end of the tail. It’s not so smooth getting the keeper in position, but the material is really tough and handles rough manipulation well. Once its in place it stays put, so a really welcome modification. Hi Joe, I think we are both half right. Omega uses the term “Professional” to connote their watches that meet mixed gas diving requirements( of which some form of HRV is required or be so air tight that helium can not enter). To drop the HRV would necessitate dropping the Professional moniker like the Seamaster 300 and the Seamaster Aqua Terra.As for the Seiko analogy a mixed gas capable watch has to be resistant to helium entering the watch, the original Seamaster PloProf had no HRV because it had a mono block case that was so tight that helium could not enter in the first place. Once Omega introduced a removable case back the auto HRV became necessary.The other points are subjective.
I think “Professional” in this case must be specific to Omega.ISO6425 simply doesn’t require an HRV. It’s a similar myth that a 10atm rated watch isn’t ISO6425 compliant.Seiko divers rated for 600m+ don’t require HRV because they don’t allow helium to enter the watch case. I think you’re right that the original Omega PloProf had such designs too.It’s fine if you like the look of the HRV but really in most cases it’s simply a liability.For most of us (including me) it’s a moot point anyway, since I spend most of my time snorkelling and free-diving only 🙂. ISO 6425 does NOT require a professional dive watch to have an HEV. The criteria are published online so you can easily check. The reason for the HEV seems to stem back to the time the Seamaster Diver was designed in 1993. Jean-Claude Biver was part of the project at Omega that designed the watch.
One of the main aims was to avoid the watch looking like a Submariner. The HEV, bracelet and handset was a big part of that aim. The “Professional” part of the name is an indication that the watch complies with ISO 6425. Again to differentiate the watch from a Submariner.
I feel that the Seamaster 300 case actually does look better off the bracelet than on it. It is a nice case and its distinctive lugs are almost lost when the awkwardly-shaped bracelet they currently have is paired with it. That said, Omega has made much nicer rubber strap designs in the past. This black rubber strap with its two pointless vertical stripes seems both boring and over-thought at the same time.
I think they are trying to mimic the lines on the metal bracelet – which are certainly not this watch collection’s best asset anyway. Omega or a high-quality rubber strap maker should make a replacement strap for this immediately. What about a rubber Nato-Style strap with a texture and whose strap isn’t uselessly too long?. Hi Bon Vivant. The Omega protocol is approved by METAS and is exclusive to them. Hi Rob, thank you for the reply. Again, my understanding is that “Master Chronometer” is a standard that the Swiss government division METAS created(with input from Omega) but is in fact an open standardRolex or any other brand can submit watches for Master Chronometer certificationOmega, or any other brand, can not submit a watch for “Superlative” certification.
If you have a source that proves that MC is only available to Omega timepieces I’d like to see it for my own education and clarification.And as for the $7500 price tag, well a stainless steel Submariner sells for over a $1000 more without ceramic/titanium, without a HRV or ISO 6425 professional dive specs, and with a fraction of the anti-magnetism of the Seamaster. Not sure why Rolex is always let off the hook by the horological media for overpriced and under spec’d timepieces. Sorry to correct you but the METAS certification is not “in-house” and to describe it as such is not a fair description. METAS is a Swiss Federal Department like the US State Department. The METAS Officials oversee Omega’s testing by sampling the tests and individual watches to make sure the criteria are fully met.

It is similar to an accountant auditing your books. Independent verification that the tests are done properly and the conditions met. The criteria for the Master Chronometer certification is set by Omega and METAS, fully published, as to what is being tested and why. The results of each individual watch can be accessed online. METAS Master Chronometer standards are open to any watch brand to try to pass.
Clearly the anti-magnetic portion of the testing process means brands like Rolex or Patek would find an attempt to pass entirely futile. Of course Rolex Superlative Chronometer is a standard set in-house with no independent agency auditing it and so you have no guarantee it means anything at all.
