Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. OMEGA’s 21st century models stay true to the original’s dive watch design, while introducing exciting new materials and movements.
On this 43.50 mm model, black ceramic [ZrO2] dominates. The case, bezel, wave-pattern dial, crown and helium escape valve, all in the same striking material, give the watch a very distinctive, uniform and sculptural look. To ensure visibility without affecting the overall aesthetic, OMEGA has introduced anthracite Super-LumiNova to the diving scale, the black PVD indexes and skeleton hands - and dot at 12H.
Completing the look is an integrated black rubber strap with black ceramic buckle. Adding some light to the darkness is a window with a clear view of the movement. Visible through the sapphire-crystal on the wave-edged caseback is OMEGA’s Co-Axial Master Chronometer Calibre 8806.
All OMEGA watches are delivered with a 5-year warranty that covers the repair of any material or manufacturing defects. Please refer to the operating instructions for specific information about the warranty conditions and restrictions.
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.)
Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
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.

Ceramic
OMEGA has unrivalled expertise in the use of ceramics, dating back more than 10 years. Taking its origin from the Greek word "keramos", ceramic is an inorganic, non-metallic substance obtained by firing at high temperatures. It allows the creation of completely dense watch parts with exceptional mechanical properties. Ceramic is one of the most popular choices for customers when selecting their timepiece, thanks to its appealing colour range and specific properties, such as it being two times lighter than stainless steel, hardwearing, highly scratch-resistant, chemically inert, hypoallergenic, environmentally friendly and non-magnetic.

Sapphire Crystal
To really appreciate the finer details of a timepiece, OMEGA uses synthetic sapphire crystal with a highly scratch-resistant and anti-reflective treatment. Before the machining and finishing processes take place, the sapphire crystals are produced under the Verneuil process, also called flame fusion. It involves the melting of the raw substance using oxyhydrogen flame and the crystallisation of the melted droplets to form a cylinder. Graded 9 on the Mohs-hardness scale (graded 1-10), the resulting sapphire crystals are virtually scratch-proof and very hard, ensuring an unhindered vision at all times.

The advantages of this watch
The advantages of this watch
Inside this timepiece are the revolutionary components that guarantee the highest standards of performance. From the Co-Axial escapement for long-lasting precision, to the silicon balance spring for superior anti-magnetism, OMEGA has conquered every challenge that matters.
Master Chronometer Certified
Superior Precision
Twice as precise as any officially certified chronometer
Our Master Chronometer watches are tested and certified twice. Firstly, the movement is tested by the Official Swiss Chronometer Control (COSC) with precision criteria of -4/+6 seconds per day. Then the complete watch and its movement undergo eight Master Chronometer tests set by the Swiss Federal Institute of Metrology (METAS) with criteria of 0/+6 seconds per day.
Everyday items such as mobile phones, metal clasps on handbags, laptops, MRI, induction hobs or automatic doors; subject a watch to magnetic fields and can affect its performance for good. To prevent the risk of permanent deviations of up to several minutes a day we've conceived movements with antimagnetic materials, such as the silicon balance spring, capable of withstanding the highest fields.
To ensure the integrity of our timepieces at depth, not just some but all watches are fully immersed in water and pressure is applied up to the point of the guaranteed water resistance. By submerging each watch in water we have chosen – yet again - to exceed normal testing standards.
Our watches are engineered to the highest standards and certified as such. Each watch destined to become a Master Chronometer must first pass 8 stringent tests. The examinations we perform for precision, magnetic-resistance, power reserve and water-resistance allow us to cover the certified watches with a comprehensive 5-year warranty.
Less servicing
Extended service intervals
Each Master Chronometer is equipped with a Co-Axial escapement, conceived to reduce the mechanical constraints inside the movement. This significantly reduces the need for lubrication and hence the need for servicing. All mechanical movements need to be serviced periodically, but an OMEGA Master Chronometer offers more time between servicing than many other watches.
Shock-resistance
During the homologation process, OMEGA watches are tested to the extreme. This phase includes shock examinations, to confirm the reliability of each timepiece, and to check that its precision is maintained after a severe impact. All OMEGA timepieces are designed to withstand shocks corresponding to a 1-metre drop on a hard wooden floor. For a standard 150g timepiece, this sudden and rapid acceleration is an equivalent force of up to 5,000 G on the watch head.
