Omega Seamaster Diver 300M 42mm Co-Axial Master Chronometer Automatic Men's Watch
This 42mm stainless steel diver features the Co-Axial Master Chronometer certified calibre 8806 automatic movement, delivering a 55-hour power reserve. The black aluminium dial displays a laser-engraved diving pattern with skeletonised hands and Super-Luminova filled indices. The black oxalic anodised aluminium bezel houses a diving scale, whilst the sapphire crystal offers scratch resistance. Water resistance reaches 300 metres, making it suitable for professional diving applications.
The watch sits on an integrated black rubber strap secured by a fold-over clasp. This iteration maintains the design lineage established in 1993, combining functional dive watch specifications with refined finishing. The Master Chronometer certification confirms adherence to METAS standards for accuracy, magnetism resistance, and chronometric performance. The combination of robust construction and certified precision movements positions this as a serious instrument for both underwater and everyday wear.
