Case: Stainless steel, with a substantial 45.5 mm diameter and about 18.9 mm thickness, giving it a robust, commanding wrist presence.

Bezel: Uni-directional rotating diving bezel — made with a blue ceramic insert — with a diving scale (often using Omega’s “Liquidmetal™” for the scale markings).

Dial: Glossy/deep blue ceramic (ZrO₂) dial with applied index hour markers (luminous), and luminous hands for excellent legibility underwater or in low light.

Sub-dials & Date: Features a classic chronograph layout — small-seconds sub-dial (usually at 9 o’clock), and a combined 60-minute / 12-hour chronograph counter (commonly at 3 o’clock), plus a date window at 6 o’clock.

Crystal: Domed scratch-resistant sapphire crystal with anti-reflective treatment (on both sides) — a high-end finishing typical of Omega’s professional watches.

Case Back: Transparent (exhibition) case-back — allowing a view of the movement.

Strap / Bracelet: Blue leather strap with rubber lining, paired with a deployant (folding) clasp — both comfortable for everyday wear and secure for diving.

Movement: Powered by Omega’s in-house Calibre 9900 — an automatic (self-winding) Master Chronometer movement certified first by COSC and then by METAS (the Swiss Federal Institute of Metrology).

Power Reserve: ~ 60 hours, thanks to twin barrels mounted in series.

Functions: Hours, minutes, small seconds, 12-hour chronograph, 60-minute chronograph, date. Also features central chronograph seconds.

Complications / Special Features: Column-wheel chronograph operation, co-axial escapement (for improved longevity and precision), silicon (Si14) balance spring (for better shock and magnetic resistance), anti-magnetic resistance up to 15,000 gauss, and visible finely finished rotor & bridges through the exhibition back.

Water Resistance: 600 meters (60 bar / ~2000 ft) — fully suitable for professional dive use.

Helium Escape Valve: Yes — located on the case edge (around 10 o’clock) — useful for saturation diving, to safely vent helium build-up.

Bezel & Bezel Scale: Dive-ready unidirectional rotating ceramic bezel, with highly legible scale — essential for timing dives.

Legibility: Luminous hands and markers + high-contrast blue dial — optimized for underwater and low-light readability.
