The Seamaster Diver 300M Collection

Since 1993, the Seamaster Diver 300M has enjoyed a legendary following. To celebrate the 25th anniversary of its release, OMEGA gave the collection a complete makeover, updating the materials and technology while retaining the original design and ocean spirit.

Exploring the Details

Now sized at 42 mm, every design detail has been rethought, including a new ceramic bezel with the diving scale in Ceragold™ or white enamel. The watches are powered by Master Chronometer Calibres 8800 or 8801 to offer extraordinarily high levels of precision, performance and magnetic resistance.

"On the bezel, white enamel offers longer-lasting whiteness and durability."

The Face of Change

The sleek dials are made from ceramic and are available in black, white, blue or PVD chrome colour. The popular wave pattern has been reintroduced (now laser-engraved) and the indexes have been raised and filled with Super-LumiNova. Even the skeleton hands have been subtly reshaped.

New Helium Escape Valve

Operated in a diving bell, one of the 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 by OMEGA with an ingenious technology, meaning the watch remains water-resistant to 50m even if the valve is accidentally opened underwater.

"Adding symmetry to the watch, the date window has been moved to 6 o'clock."

Rear View

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 Master Chronometer Calibre.

The Full Collection

In total, there are 17 new Diver 300M models, including 8 in stainless steel, 8 in a mix of stainless steel and gold - and a model in Sedna™ gold. Each model is presented on an integrated black or blue rubber strap, or a traditional metal bracelet (with a new ergonomic design and a patented extendable foldover rack-and-pusher with diver extension).


OMEGA's Seamaster Diver 300M collection includes 43.5 mm models crafted from ceramic and grade 5 titanium. Powered by the Master Chronometer Calibre 8806, they feature a bezel and laser-engraved dial in black ceramic and can be worn on an integrated black rubber strap or striped NATO strap.


Limited to 2,500 pieces, this rare model follows an original 1993 design by using tantalum for the base of the bezel, as well as in the bracelet. The metal's blue-grey tones offer a subtle contrast to the grade 2 titanium and 18K Sedna™ gold, which are used for the other features of the watch.
