Since 1993, the Seamaster Diver 300M has enjoyed a legendary following.
This 42 mm model is a Limited Edition of 2,500 pieces and features a brushed case made from grade 2 titanium, with a crown, bezel ring and helium escape valve in 18K Sedna™ gold. In contrast, OMEGA has used tantalum to create the base of the bezel for a distinctive blue-grey tone.
The titanium dial features positive sun-brushed waves. The skeleton hands and raised indexes are 18K Sedna™ gold and are filled with white Super-LumiNova.
The watch is presented on a grade 2 titanium bracelet with tantalum and 18K Sedna™ gold links. An image of the OMEGA Seahorse can be found on the transparent caseback, through which you can see the OMEGA Master Chronometer Calibre 8806 inside.
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Helium escape valve
Decompression system which allows helium to escape from inside the watch when the watch is worn for professional use in pressure chambers. (Long-term underwater work, crude oil exploration, etc.)
- Limited edition (2,500)
A series of watches whose production run is determined in advance of production and limited to a set number.
Master Chronometer Certified
Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Transparent case back
A transparent case back - frequently made of sapphire - makes it possible to see the movement inside the watch.
Unidirectional rotating bezel
A bezel which turns in only one direction. Particularly useful for divers who cannot accidentally rotate it in the wrong direction, which could cause them to miscalculate their dive times. A rotating bezel makes it easy to measure elapsed time.
