Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. Now, 25 years later, a bold new collection has arrived.OMEGA is unveiling a complete facelift of this famous watch in 2018, with 14 unique models, including 6 in stainless steel and 8 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.
The dials are also made from polished ceramic and are available in black, blue or sun-brushed PVD chrome color. Most notably, OMEGA has reintroduced the wavy pattern 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 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.
A real diving watch
For a diver, measuring time spent underwater is crucial. On the new Seamaster 300M, the all-important rotating bezel has been given a fresh design twist. With a luminescent dot at 12 o’clock, the iconic diving bezel is now made from ceramic with the diving scale in Ceragold™ or white enamel.
Professional divers know that helium molecules expand during decompression and can pop the crystal face and caseback. It's important to set those He molecules free. One of the Diver 300M’s most important details has always been its helium escape valve. For the new models, the valve has been given a conical shape and has been patented with an ingenious new technology. Essentially, the update now means that if the Helium Escape Valve is accidentally opened underwater, the watch is guaranteed to still remain water-resistant up to 50 meters.
It goes without saying that a diver needs to see the watch display clearly underwater, especially in murky conditions, so on the new 300M, all 12 indexes and hands have been filled with Super-LumiNova to keep the time visible in darkness. When it comes to keeping the Diver firmly attached to the wrist, the metal bracelets feature OMEGA’s patented extendable foldover rack-and- pusher with a helpful diver extension, to make extra room for the thickness of a diving suit.
Magnetic forces in electronic devices used on land, on deck and even under the sea can throw a timepiece out of synch. What’s more, diving equipment often includes magnetic devices. That’s why each new Diver 300M has been given a Master Chronometer Calibre 8800, built with non-ferrous materials that can resist the effects that magnetism causes. In fact, the movement and its watch have passed the 8 stringent Master Chronometer tests set by METAS that include examinations under strong magnetic fields of 15,000 gauss.
