Seamaster PloProf 1200M

The Omega Seamaster PloProf 1200M stands as a pinnacle of engineering and functionality in Omega’s esteemed Seamaster collection, specifically designed for professional divers and underwater explorers who demand uncompromising reliability and durability. Let’s delve into what makes the Seamaster PloProf 1200M a standout in the world of dive watches:

Purpose-Built Design

The Seamaster PloProf 1200M (short for Plongeur Professionnel, French for Professional Diver) was originally introduced in 1970 and reimagined in 2009 with updated materials and technology. Its robust and distinctive case design, typically crafted from stainless steel, features a unique asymmetrical shape that ensures optimal ergonomics and wrist comfort, even during prolonged underwater expeditions. The oversized crown at the 9 o’clock position is protected by a patented locking mechanism, enhancing water resistance and preventing accidental adjustments.

Extreme Water Resistance

As its name suggests, the Seamaster PloProf 1200M boasts an impressive water resistance of 1200 meters (4000 feet), making it suitable for deep-sea diving and saturation diving operations. The screw-in case back and crown, along with the solidly constructed case, provide exceptional resistance to water pressure, ensuring the watch’s integrity in the most extreme underwater conditions.

Professional-Grade Movement

Powering the Seamaster PloProf 1200M is Omega’s Co-Axial Master Chronometer Calibre 8912/8910, depending on the model, certified by METAS (Swiss Federal Institute of Metrology). This automatic movement offers superior precision, magnetic resistance up to 15,000 gauss, and a power reserve of up to 60 hours. The Co-Axial escapement reduces friction and enhances long-term reliability, ensuring accurate timekeeping in demanding environments.

Functional Dial and Bezel

The dial of the Seamaster PloProf 1200M features large, contrasting hour markers and bold hands coated with Super-LumiNova, ensuring optimal readability in low-light conditions underwater. The uni-directional rotating bezel, with its orange or black aluminum insert, allows divers to track elapsed dive time accurately and complements the watch’s rugged and purpose-driven aesthetics.

Ergonomics and Comfort

Despite its robust build, the Seamaster PloProf 1200M is designed for comfort and usability. The integrated bracelet or rubber strap options, coupled with the adjustable clasp or extension system, ensure a secure and comfortable fit on the wrist. This ergonomic design allows for ease of movement and adjustment, critical for professional divers navigating challenging underwater environments.
