Where the standard 42mm Diver 300M runs the Caliber 8800, the 44mm chronograph steps up to the Caliber 9900 — Omega's flagship in-house chronograph movement with column wheel, vertical clutch, twin barrels in series, and METAS Master Chronometer certification. It also carries an independently adjustable hour hand for quick time zone changes, making it a genuine travel chronograph on top of being a 300-meter dive watch. The case is full stainless steel with polished black ceramic pushers and a polished black ceramic bezel with a white enamel diving scale — the ceramic elements aren't decorative, they're functional scratch resistance where the watch needs it most. The dial is black ceramic with Omega's signature laser-engraved wave pattern in positive relief, rhodium-plated hands and indices filled with white Super-LumiNova, and a conical helium escape valve at 10 o'clock for saturation diving capability. At 44mm and 17.2mm thick, this is a watch that commands presence on the wrist, and the 9900 visible through the wave-edged sapphire caseback — rhodium plated with Geneva waves in arabesque — backs up every millimeter of it with genuine horological substance.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eModel: Omega Seamaster Diver 300M Co-Axial Master Chronometer Chronograph 44mm\u003cbr\u003e Reference: 210.32.44.51.01.001\u003cbr\u003e Caliber: Omega 9900 — 54 jewels, 28,800 vph (4 Hz), METAS Master Chronometer certified, column wheel chronograph with vertical clutch and Co-Axial escapement, Si14 silicon balance spring, twin barrels in series, anti-magnetic to 15,000 gauss\u003cbr\u003e Case Material: Stainless steel\u003cbr\u003e Case Diameter: 44mm\u003cbr\u003e Case Thickness: 17.2mm\u003cbr\u003e Bezel: Unidirectional rotating, polished black ceramic with white enamel diving scale\u003cbr\u003e Crown: Screw-down, stainless steel\u003cbr\u003e Pushers: Polished black ceramic\u003cbr\u003e Crystal: Domed scratch-resistant sapphire crystal with anti-reflective treatment on both sides\u003cbr\u003e Caseback: Transparent sapphire crystal with wave-edged design\u003cbr\u003e Helium Escape Valve: Conical design at 10 o'clock\u003cbr\u003e Dial: Black ceramic with laser-engraved wave pattern, rhodium-plated hands and applied indices with white Super-LumiNova, rhodium-plated subdial hands, date at 6 o'clock\u003cbr\u003e Strap: Black rubber\u003cbr\u003e Clasp: Pin buckle\u003cbr\u003e Movement: Automatic self-winding, rhodium plated with Geneva waves in arabesque\u003cbr\u003e Power Reserve: 60 hours\u003cbr\u003e Water Resistance: 300 meters (30 bar)\u003cbr\u003e Functions: Hours, minutes, small seconds, date, chronograph (central elapsed seconds, 60-minute recorder, 12-hour recorder), independently adjustable hour hand\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCondition Report\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eCase: 10\/10\u003cbr\u003e Bezel: 10\/10\u003cbr\u003e Crystal: 10\/10\u003cbr\u003e Dial\/Hands: 10\/10\u003cbr\u003e Strap: 10\/10\u003cbr\u003e Clasp\/Buckle: 10\/10\u003cbr\u003e Caseback: 10\/10\u003cbr\u003ePolishing Status: Unpolished\u003cbr\u003ePhotos taken on strap at standard length, fitting approximately 16–20cm (6.3–7.9 inch) wrists.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eDelivery Contents\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eComplete set — box, warranty card, instruction manual, pictogram card\u003cbr\u003e Please refer to photos for full contents.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eService \u0026amp; Authenticity\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eThe watch is running at 326 degrees of amplitude on the timegrapher.
