Now, 25 years later, Omega has unveiled a bold new collection, giving a complete facelift for this famous watch, with 14 unique models, including six in stainless steel and eight in a mix of stainless steel and 18K gold.

Now sized at a larger 42 mm, each new Diver 300M has been given a Master Chronometer Calibre 8800, instantly taking the collection into a higher realm of precision, performance and magnetic resistance.

Every detail of the outward design has also been rethought, including the iconic diving bezel, which is now made from ceramic with the diving scale in Ceragold or white enamel (for longer-lasting whiteness and durability).

The dials are also made from polished ceramic and are available in black, blue or sun-brushed PVD chrome colour. Most notably, Omega has reintroduced the wavy pattern (now laser-engraved) that was a popular feature of the original design.

All indexes have been raised and filled with Super-LumiNova and, to keep track of the days, the date window has been moved to 6 o’clock. Even the skeleton hands (rhodium-plated, 18K gold, or blued) have been subtly reshaped, which fans of the model will surely notice.

Turning the watch over reveals a wave-patterned edge on the caseback, as well as sapphire crystal, through which you can see the Metas-approved movement.

Finally, each model is presented on a traditional iconic metal bracelet or an integrated black or blue rubber strap. The metal bracelets feature a new ergonomic design and have been closely integrated to the case.

For a diver, measuring time spent underwater is crucial (for obvious reasons). On the new Seamaster 300M, the all-important rotating bezel has been given a fresh design twist.
