Specialist sources identify that reference as a 39.5 mm ceramic model, but an exact-reference OMEGA specification sheet was not available to confirm its full specifications. It is also important not to confuse it with a similarly sized steel Planet Ocean—or assume it belongs to OMEGA’s redesigned 2025 generation.
Which watch does the title describe?
The strongest match is OMEGA Seamaster Planet Ocean 600M reference 215.92.40.20.01.001, described by specialist sources as a black ceramic watch with a 39.5 mm case. WatchCharts identifies the reference, and Topper Fine Jewelers’ search result independently describes it as a 39.5 mm black ceramic Planet Ocean. These are secondary-source identifications, rather than an exact-reference OMEGA product sheet. WatchCharts
The reference number matters: OMEGA’s regional page for a 39.5 mm Planet Ocean covers steel reference 215.30.40.20.01.001, not the ceramic watch. It cannot be used as a specification sheet for 215.92.40.20.01.001. OMEGA Taiwan’s page for the steel reference
What makes the ceramic version unusual?
A smaller case in the Planet Ocean 600M line
The 39.5 mm diameter is the clearest point of distinction established for this reference. It places the watch at the more compact end of the Planet Ocean 600M format, while retaining the line’s 600M designation. Diameter alone does not determine how a watch wears: case thickness, lug-to-lug length, bezel dimensions and strap fit also affect wrist presence, and those measurements are not confirmed here for the ceramic reference.

Black ceramic rather than steel
The case material is the other defining feature. The exact reference is identified by specialist sources as ceramic, whereas the similarly sized OMEGA regional model is steel-cased. The contrast is useful when identifying the watch, but the available evidence does not establish detailed material properties, finishing, weight, or a component-by-component material breakdown for this exact reference.
What specifications are confirmed—and what are not?
For reference 215.92.40.20.01.001, the evidence supports the model identification, black ceramic construction and 39.5 mm diameter through specialist sources. It does not provide an exact-reference official product sheet or manual. A WatchCharts listing associates the ceramic reference with calibre 8800 and a 55-hour power reserve, but those figures are not independently confirmed by an exact OMEGA document here and should be treated as provisional rather than definitive.

OMEGA’s Taiwan page does state 600 m / 60 bar water resistance and calibre 8800 for steel reference 215.30.40.20.01.001. Those are specifications of that steel model, not verified specifications for the ceramic reference. The page marks the steel watch as no longer available. OMEGA Taiwan’s steel-model product page

On 18 November 2025, OMEGA announced a fourth-generation Planet Ocean as a complete redesign, unveiling seven new watches. The announcement frames the update as arriving 20 years after the first Planet Ocean. It is a collection-level launch announcement; it does not establish that reference 215.92.40.20.01.001 is among those seven watches. OMEGA’s 2025 launch announcement

For shoppers, this distinction prevents a common mix-up: the title’s specific black ceramic 39.5 mm reference should not be presented as one of the new-generation models without model-specific confirmation. Its current regional availability and price are not established by the available sources.

What to check before buying one
- Match the reference. Confirm that the watch is 215.92.40.20.01.001; a 39.5 mm Planet Ocean listing may instead describe a steel model.
- Verify the exact configuration. Check case material and condition against clear photographs and seller documentation rather than relying on a generic Planet Ocean description.
- Request model-specific documentation. Ask for the OMEGA papers, manual or product documentation that corresponds to the reference, especially if movement, water resistance or other detailed specifications matter to your decision.
- Confirm price and availability directly. No current regional price, authorized inventory or live marketplace stock for this exact reference is established here; those details can vary by seller and location.
