OMEGA Seamaster 300 Co‑Axial Chronograph Implements the Most Sophisticated Technologies

OMEGA created the Seamaster 300 series watches which were specifically for divers and professionals working underwater back in 1957. With enhancements and upgrades through the years with modern technology, the OMEGA Seamaster 300 Diver watch is no longer just a professional grade watch, but a luxurious timepiece that you can wear everywhere in style whether you are on land or below water.

Washed and weathered look canvas watch band paired with OMEGA Seamaster Chronograph

This OMEGA Seamaster Diver 300M Chronograph features a lacquered blue dial with a 30-minute recorder at 3 o'clock, a 12-hour recorder at 6 o'clock, and a small seconds dial at 9 o'clock. The polished blue ceramic unidirectional rotating bezel is mounted on a 44 mm stainless steel case with a helium-escape valve and an integrated date corrector at 10 o'clock.

Another washed canvas watch band in stylish military colors

This particular Seamaster 300 model operates with a 3300 movement. Based on the previous generation of column-wheel chronograph movements, the 3300 movement has two important features added to it.

1) By adding a Co-Axial escapement

2) Replaced with Silicon hairsprings.

Hairspring, also referred to as a balance spring, is what makes your watch tick. The spring was usually made out of meta that’s attached to the balance wheel. By replacing the hairspring from made of metal to silicon, it’s incredibly light, durable, anti-magnetic, and can withstand both temperature changes and pressure changes with ease.
