Description

Reliable even at 4000 feet beneath the waves, the famous Ploprof timepiece has a long history as OMEGA's most water-resistant divers' watch.

While retaining the original sturdy and bold appearance, this new edition has been updated with OMEGA's Co-Axial Master Chronometer Calibre 8912, featuring revolutionary technology renowned for its anti-magnetic resistance, chronometric performance, and precision.

The unique case combines 18K Sedna™ gold along with grade 5 titanium for lightweight comfort. Sedna™ gold has also been used on the hands and indexes, with Super-LumiNova for increased visibility. Completing the look, a polished blue bezel has been added with OMEGA Ceragold™ numerals, as well as a blue lacquered dial.

The sophisticated style of this watch clearly recalls the dark colours of the ocean, and the polished titanium "sharkproof" mesh bracelet further adds to the sense of exploration and adventure. The watch is delivered in a special presentation box along with an additional dark blue rubber strap.

5-Year Warranty

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.

Features

Anti‑magnetic

Anti-magnetic Anti-magnetic

The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Bi‑directional rotating bezel

Bi-directional rotating bezel Bi-directional rotating bezel

A bezel which can be turned clockwise or anti-clockwise. Rotating bezels can be used to time events, measure elapsed times, or read second or third time zones.
Ceragold

Ceragold Ceragold

Ceragold is the result of a process that allows the incrustation of 18K gold into a ceramic bezel. The bezels made of ceramic and the Ceragold are perfectly smooth to the touch.
Chronometer

Chronometer Chronometer

Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Helium escape valve

Helium escape valve 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.)
Screw‑in crown

Screw-in crown Screw-in crown

Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Transparent case back

Transparent case back Transparent case back

A transparent case back - frequently made of sapphire - makes it possible to see the movement inside the 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.

01 / 06

Twice as precise as any officially certified chronometer

Master Chronometer Certified

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/+5 seconds per day.

Proprietary anti-magnetic materials

Master Chronometer Certified

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.

Water-resistance

Master Chronometer Certified

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.

Durability

Master Chronometer Certified

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.

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

A selection of test watches face shock-resistance examinations that are equivalent to 5,000 g (1 g is equal to the force of gravity at the Earth's surface) to ensure our complex mechanical mechanisms are also extraordinarily robust. Not just for everyday use but for active sports such as golf and sailing.
