Case #718 — Omega Seamaster Diver 300M Co‑Axial Master Chronometer 42 mm, Grey Dial / Titanium Bezel

Ref. 210.32.42.20.06.002

Status: Available

Condition: Like New Pre-Owned

Year: 2026

🔎 Case Notes

Most Seamaster Diver 300M examples that cross the desk are blue, black, or wave-patterned, with a date window at six. This one is none of those things. Introduced in 2024, the 210.32.42.20.06.002 pairs a stainless steel case with a brushed grey dial and a grade 5 titanium bezel carrying a laser-ablated diving scale rendered in positive relief — a quieter, more industrial reading of a watch that usually announces itself in glossy ceramic and enamel.

The dial is PVD-coated stainless steel with a brushed finish, and it behaves very differently from the lacquered dials elsewhere in the family: in flat light it reads as a cool graphite grey, and under direct light the brushing catches as a metallic sheen rather than a gloss. Because this is the no-date configuration, the dial stays symmetrical, with nothing interrupting the six o'clock index. Beneath it runs the Omega Calibre 8806, a Co-Axial, chronometer-grade automatic — visible through the sapphire-crystal caseback.

The bezel deserves a second look. The grade 5 titanium insert carries its diving scale in positive relief with a single dot of white Super-LumiNova at 12 o'clock, so the markings stand proud of the surface rather than being filled into it. It is a tactile, tool-led detail, and the titanium keeps weight off the top of the case.

Condition is the other part of this file. BST's inspection found no notable signs of wear. We will not call it unworn — but it presents about as close to unworn as a pre-owned watch reasonably gets. It arrives with Box, Papers, and Cards, dated 2026, on its factory grey rubber strap with the folding clasp, currently sized for an approximately 7¾-inch wrist.

🌟 Collector Provenance

The Seamaster Professional Diver 300M has had a committed following since 1993, and for most of that time the formula has been fixed in the collective memory: wave dial, ceramic bezel with enamel scale, date at six, skeleton hands. The 2018 redesign modernised all of it without abandoning any of it. This reference is what happens when Omega steps outside that template inside the same case.

Three decisions separate it from the mainstream Diver 300M. First, the dial is not a wave dial — it is a brushed PVD-coated steel surface, read as texture rather than pattern. Second, the bezel is titanium rather than ceramic, with relief markings instead of enamel-filled engraving. Third, and most consequentially for how the watch looks, there is no date aperture. The no-date Diver 300M configurations have always been the minority within a date-dominated collection, and collectors who care about dial symmetry tend to seek them out specifically.

Introduced in 2024, this configuration is still comparatively fresh, and it sits on the understated end of a line better known for high-contrast colour. For a buyer who likes the Diver 300M's architecture but not its usual volume, it is one of the more interesting answers the collection currently offers.

🌟 Technical Provenance

Calibre 8806 is a Co-Axial, chronometer-certified automatic and is Omega's no-date Master Chronometer workhorse. The Master Chronometer standard matters here: beyond COSC chronometer certification of the movement, the complete, cased-up watch is tested to METAS criteria covering precision, power reserve, water resistance and resistance to magnetic fields of 15,000 gauss. In practical terms, this is a dive watch you can set down next to a laptop, a phone, or a tablet case without thinking about it.

Power reserve is approximately 55 hours, with water resistance rated to 30 bar — 300 metres, and the specification includes a helium escape valve, the feature that gave the Seamaster Professional its identity in the saturation-diving era and that Omega has never dropped from the line.

The material choices are functional rather than decorative. Grade 5 titanium is lighter than steel and highly corrosion resistant, which is a sensible choice for the one component most exposed to knocks and salt water. Rendering the scale in relief rather than as inlaid enamel means the markings are part of the metal itself.

🧾 From the Case File

At 42 mm with a 20 mm lug width, this is the full-size Diver 300M, but the rubber strap and titanium bezel change how it wears compared with the bracelet versions — less mass on the wrist, and the weight sits lower and more centred. The strap is currently fitted for an approximately 7¾-inch wrist via the folding clasp, which also means it can be adjusted down easily rather than requiring link removal.

The grey dial is the practical argument. It is far more neutral than the blue or black ceramic-bezel versions, and the brushed finish keeps it legible across a wide range of light. If you want a 300-metre diver that works under a shirt cuff and does not read as a statement piece, this configuration does that better than almost anything else in the collection.

Against buying new: this example is a 2026 watch in Like New Pre-Owned condition, complete with Box, Papers, and Cards, and still inside Omega's five-year factory warranty period subject to the card's activation date and Omega's terms. You are taking on a watch that has effectively not been used, with its documentation intact.

Note on performance: BST has not supplied timing or amplitude test results for this example, and we make no claim as to measured rate.

🗝️ BST Verdict

A no-date, titanium-bezel Diver 300M is the quiet member of a loud family — same 300-metre case, same Master Chronometer engineering, none of the usual visual signalling. The brushed grey PVD dial and relief-cut titanium scale give it a tool-watch seriousness that the ceramic-and-enamel versions trade away for colour.

Presented in Like New Pre-Owned condition with no notable wear, dated 2026, complete with Box, Papers, and Cards, and still within the factory warranty period. A very clean example of one of the more interesting configurations Omega currently builds in this case.
