The OMEGA Seamaster Diver 300M Black Black reference 210.92.44.20.01.003 is a 43.5 mm ceramic dive watch with a black rubber strap, OMEGA Co‑Axial Master Chronometer Calibre 8806 and a deliberately low-contrast all-black dial. Its 14.47 mm thickness and 51.50 mm lug-to-lug length matter more to fit than the diameter alone. OMEGA rates it to 30 bar (300 metres/1,000 feet) and states that the movement resists magnetic fields to 15,000 gauss.
Identify the exact Black Black
Several Seamaster Diver 300M Black Black references look similar but are not the same watch. This article concerns 210.92.44.20.01.003: the full-black-ceramic case and bezel on a black rubber strap. Reference 210.92.44.20.01.001 is a black-ceramic and grade 5 titanium configuration, while 210.92.44.20.01.002 is the NATO-strap version. Confirm the reference on the case, warranty card or retailer listing before comparing prices or ordering parts.
Specifications at a glance

| Lug-to-lug | 51.50 mm (OMEGA Japan specification) |
| Lug width | 21 mm |
| Approximate weight | 114 g, as listed by OMEGA Japan |
| Movement | Self-winding Co‑Axial Calibre 8806 |
| Power reserve | 55 hours |
| Certification | METAS Master Chronometer approval |
| Magnetic resistance | Up to 15,000 gauss |
| Water resistance | 30 bar (300 m/1,000 ft), manufacturer rating |
| Strap and clasp | Black rubber strap with ceramic pin buckle |
| Other hardware | Helium escape valve, screw-in crown, unidirectional bezel, transparent caseback |
These figures are OMEGA product specifications; they are not independent test results. A US retailer has used a rounded “44 mm” title, but its description and OMEGA’s specifications identify the case as 43.5 mm.
How the 43.5 mm case will fit
“Is the Omega Seamaster Black Black too big?” cannot be answered from diameter alone. The 51.50 mm lug-to-lug measurement gives a better indication of the span across the wrist, while the 14.47 mm thickness determines how prominently it sits under a cuff. At approximately 114 g, the ceramic-and-rubber configuration is not an ultra-light watch. Wrist comfort is personal, so these dimensions should be checked against a watch that already fits you rather than treated as a guaranteed wear impression.

The all-black dial is a deliberate trade-off
Tourneau’s description identifies anthracite Super-LumiNova, black PVD indexes and black PVD skeleton hands, alongside the ceramic wave-pattern dial, ceramic crown and ceramic helium escape valve. That treatment creates a stealth appearance, but the dark-on-dark contrast is intentionally less conspicuous than a conventional silver-marker Diver 300M. The specifications establish the materials and luminous compound, not a measured low-light legibility result.
Movement and dive-watch equipment
Calibre 8806
OMEGA lists the self-winding Co‑Axial Calibre 8806 with a 55-hour power reserve. METAS Master Chronometer approval and the stated 15,000-gauss resistance are manufacturer-listed performance and certification claims for this reference.

Controls and caseback
The watch has a screw-in crown, a unidirectional rotating bezel for elapsed-time tracking, a helium escape valve and a transparent caseback. OMEGA’s product sheet lists 30 bar water resistance, equivalent to 300 metres or 1,000 feet. That rating is not the same as an independently published dive test.
Black Black family comparison
| Reference | Material or configuration identified in the sources | Strap | Dimensions/price in the supplied listings |
|---|---|---|---|
| 210.92.44.20.01.003 | Full black ceramic configuration | Black rubber | 43.5 mm; 14.47 mm thick; 51.50 mm lug-to-lug; Japan price ¥1,584,000 listed in 2026 |
| 210.92.44.20.01.001 | Black ceramic and grade 5 titanium variant | Not stated | Not stated |
| 210.92.44.20.01.002 | Nearby Black Black family variant | NATO | Not stated |
The variants should not be assumed to share identical construction, weight or pricing simply because their names are similar.

Price and market context
OMEGA Japan listed reference 210.92.44.20.01.003 at ¥1,584,000 when checked in 2026. A Tourneau US listing displayed $10,700 at crawl time. Both are dated market snapshots: currency, tax treatment, stock and retail prices can change, and neither figure is a universal worldwide MSRP or a guaranteed current quote.
Water resistance and practical care
OMEGA’s general watch manual recommends having water resistance tested annually at an authorized service centre. It also advises rinsing the watch after sea swimming and cleaning waterproof cases and rubber straps with soapy water and a toothbrush, followed by drying with a soft cloth.
- Do not operate the crown underwater.
- Use an authorized service centre for the recommended water-resistance check.
- Rinse salt water from the case and strap after marine use.
- Confirm that any replacement 21 mm strap has end links and hardware compatible with this exact reference; width alone does not prove fit.
Who should choose it?
This reference suits a buyer who wants the Seamaster Diver 300M’s tool-watch architecture in a monochrome ceramic execution and accepts the visual compromise of dark indexes and hands. Buyers prioritizing maximum dial contrast, a thinner profile or a lighter case should compare other Diver 300M configurations rather than assuming the Black Black is an interchangeable cosmetic option.
