Seamaster Diver 300M 42 mm
210.30.42.20.01.018
This 42 mm model is crafted in stainless steel and includes a black oxalic anodized aluminium bezel ring with a diving scale in white Super-LumiNova.
Black aluminium is also used to create the dial, which features rhodium plated skeletonized hands and indexes that are filled with white Super-LumiNova. The colour orange is used for the central seconds hand, the four quarter indexes, and Seamaster name, while the OMEGA logo is transferred in white.
The watch is presented on a brushed mesh bracelet with clasp, and is driven by the OMEGA Co-Axial Master Chronometer Calibre 8806, which can be seen through the sapphire crystal caseback.

Features
Features
Anti-magnetic : The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Chronometer : Label given to a watch which has been successfully tested by an accredited and independent laboratory in order to receive a certificate compliant with the chronometer ISO 3159 standard.
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.)
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).
Screw-in crown : Self-locking crown, screwed into the tube of the case, used for highly water resistant divers’ watches.
Transparent caseback : A transparent caseback – 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.
