The Omega Automatic Seamaster Calendar introduced in 1956 was the first Seamaster model with calibre 28 SC-503 with a date, quick setting system activated by moving the watch hands to and from 11 ‘o clock and midnight. It has a water resistant 18-carat yellow golden case and a re-inforeced crystal. This iconic golden version from ca.1958 is in an overall very good condition. Calibre 503 movement, 2849C model.
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 Defence during WWII, the Seamaster was the civilian answer to the robust models designed to resist the most gruelling conditions imaginable.
Now let’s dive into the technical details of this calibre.
The Omega calibre 503 is a 1 20-jewel DATE movement and the first attempt by Omega at a quick-set mechanism, advancing the dated by turning the hands backward past 10:00 o'clock and forward again. Th movement beats with a frequency of 19800 A/h and has a power reserve: 46 hours. Th movement has a diameter of 28 mm
What is not to love on the design of this early golden Seamaster?
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.
