2021 Omega Seamaster 300 Master Co-Axial Chronometer 41mm reference

The Omega Seamaster has been a staple of the Omega line since its release in 1948, and taking this a leap forward, this particular Omega Seamaster uses the innovative Co-Axial movement.

Made in a robust stainless steel case measuring 41mm across, this watch sits so well on the wrist and has a wonderful solid heft to it that feels fantastic to wear day or night.

The black dial is so easy to read and has a style reminiscent of the 1950's and 1960's Omega watches with the larger arrow head on the hour hand and tapering index markers.

Turning the watch over reveals the gorgeous automatic co-axial movement that has a power reserve of sixty hours, and is under Omega warranty until 2026.

Complete with box and papers, this is a stunning watch with an incredible movement to match.

2021 Omega Seamaster 300 Master Co-Axial Chronometer 41mm reference

A brief history of the Omega Seamaster.

First released in 1948 which was also Omega's 100th Anniversary, the Omega Seamaster was designed to be a robust watch while still being very elegant making it one of the world's first watches that could be worn with a suit and tie as well as a wet suit in an age where blue collar watches and white collar watches never overlapped.

The Omega Seamaster was in fact born as a result of World War II where the British were after a watch with superior reliability and water resistance with very high precision.

After the war the Omega Seamaster became known as the watch to have on your wrist and one that would never let you down, and is a testament to the classic vintage Omega Seamaster watches that we have on offer.

How often should I service my Omega?

As per official OMEGA guidelines, the service frequency depends on the use of the watch and the environment in which it is worn. The water resistance can, for example, be affected by the aging of the gaskets or by an accidental shock. Therefore, we recommend that you have the water resistance checked once a year and a complete service performed every 5 to 8 years.

Kalmar Antiques are now an authorised OMEGA watch service centre, based in the heart of Sydney in the Queen Victoria Building.

Should I take my watch to an authorised OMEGA service centre?
