History of the Omega Seamaster

In 1932 Omega had launched their first real divers watch the rectangular Marine Master. And the expertise and designs from that watch were carried forward to create the first Omega Seamaster 300. Launched in 1948 to coincide with Omega’s centenary, the Seamaster is Omega’s most veteran line in the current collection and the granddaddy of Omega’s powerful family of diving instruments -including the Seamaster Diver 300m Bond watch. As the direct descendant of Omega’s utilitarian wristwatches supplied in bulk to the British Ministry of Defense during WWII, the Seamaster was the civilian answer to the robust models designed to resist the most grueling conditions imaginable.

 René Bannwart is considered the father of the Omega Seamaster line. The man who would later found Corum had begun building Omega’s design department in 1940. This was new. At that time, sketches for new models were usually drawn by draftsmen in watch-case factories. Bannwart’s decision set Omega on a new path that other brands would soon follow. To celebrate Omega’s 100th anniversary, Omega sales director Adolphe Vallat asked Bannwart to develop a sporty, robust and waterproof wristwatch. Bannwart felt that Vallat wasn’t giving him enough time, so he presented one of his case designs with the comment “much too clunky.” To Bannwart’s surprise, Vallat was delighted. The result was the Seamaster family. It had its origins in watches supplied to Britain’s Royal Air Force in World War II. The 1948 civilian version of the pilots’ watch had a water-resistant case (to 50 meters), a screwed caseback with lead gaskets, a reinforced crystal, a silvered dial, and polished and riveted Arabic numerals.

The first Omega Seamaster was modeled after the waterproof wristwatches made for and worn by the British military during World War II. What distinguished the Seamaster from its diving watch predecessors was its O-ring gasket which improved its water-resistance. Previously water-resistant watches relied on lead or shellac gaskets which were easily affected by temperature changes like those a diver would experience at various depths. Omega turned to the submarines used during WWII for inspiration and included a resilient rubber gasket in the Seamaster’s final design. This new case remained intact at depths up to 60 meters and temperature ranges between -40 degrees and 50 degrees Celsius.

 

Omega engineers was so confident of the Seamaster’s durability, they attached one to the outside of an aircraft and flew it over the North Pole in 1956.

In 1957 the world was greeted by the arrival of Omega’s famous broad arrow trilogy: Speedmaster, Railmaster and importantly the Seamaster 300. The Seamaster 300 was Omega’s first true divers watch. The watch 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 1960 by CK14.755 (calibre 552) The CK14.755 reference did not have the “broad arrow” hands and also used a different movement (Caliber 552).

In 1962 came the second generation of the Seamaster 300 which then became ST165.014 and thereafter refrence ST165.024 in 1963-64. The 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. Jacques Cousteau and his team used the Omega Seamaster 165.024 during the under water experiment Precontinent II that was conducted in the Red Sea in July 1963.

Although the Omega Vintage website states the SM300 was in their International Collection from 1962 - 1969 it probably did not reach the dealers until 1964. It was available either with a metal bracelet or leather strap.

 

Now let’s dive into the technical details of this caliber.

Initially the SM300 was available as non-date watch with a center sweep second hand. The majority of non US watches used an Omega cal.552 movement with 24 jewels created in 1958. The Omega cal.550 movement with 17 jewels created in 1960 was chosen specifically for the American market, as watches that exceeded 17 jewels were subject to more tax in the US. The compromise was made in the automatic assembly, where brass bushes were used instead of jewels. The brass bushes were prone to wear, and it is not uncommon to see cal.550 movements that have had both the upper and lower automatic bridges changed to the jeweled version.

The date version was introduced in 1967 as case reference 166.024 and used an Omega cal.565 movement with 24 jewels created in 1965.

The SM300 name suggests it to be waterproof to 300 meters but the Omega Vintage website and period catalogues list it as waterproof to 660 feet or 200 meters.

This particular Omega Seamaster 300M has just undergone a full service. This work was carried out by an Omega Service Center certified watchmaker using original parts.

As with all of our pre-owned watches this watch comes with a full 12 month WRIST ICONS warranty that will be invoked from the day of purchase. Further: everything is cleaned before sending the items.
