The Omega Planet Ocean 600M in reference 21732422101001 arrives as the fourth generation with a revised dial concept. Three colorways are on offer: black, blue, and orange — each matte-finished, with Arabic numerals. The standout detail: no date. The no-date configuration is not a cost-cutting move but a deliberate design decision — it clears the dial and brings the Planet Ocean closer to its dive-watch roots.
The calibre 8912 powers the watch from within: a Co-Axial movement with 60 hours of power reserve and Master Chronometer certification to the METAS standard. Magnetic resistance extends to 15,000 Gauss, with a daily rate of between 0 and +5 seconds. On the secondary market, the fourth generation trades between $5,486 and $6,172 in 2025, depending on colorway — the orange variant has traditionally drawn the lowest demand of the three.
## Three Bezels That Set the Tone
The ceramic bezel in black and blue carries white enamel indexing on the 60-minute scale, with no decorative flourishes. The orange variant, by contrast, features an all-orange enamel fill and remains the most eye-catching model in the lineup. All three ceramic bezels are scratch-resistant over the long term — a compelling argument in the market, since older Planet Ocean generations with aluminum inserts regularly rack up refinishing costs.
Collectors in German-language forums have been referring to the model as "Gen 4 PO" or "4th Gen Planet Ocean" since 2024. The no-date designation has taken hold alongside it, drawing a clear line between this lineup and the date-equipped variants within the 42 mm class.
Brand profile: Omega
Omega is the second most counterfeited Swiss watch brand. The Speedmaster and Seamaster are especially targeted. Pay close attention to movement details (Co-Axial) and dial textures.
- Speedmaster: The chronograph reset hand must snap back precisely to 12 o'clock — fakes stop 1–3 seconds off or wobble
- Speedmaster (Hesalite): The Omega logo is micro-laser-etched on the UNDERSIDE of the Hesalite crystal — only visible at a specific angle and in the right light — fakes omit it or place it incorrectly
- Seamaster: The wave-pattern dial must be ENGRAVED (tactile relief) — printed/flat wave lines = fake
- DON (Dot Over Ninety): small dot ABOVE the '90' on the Speedmaster tachymeter bezel — position/size often wrong on fakes
Serial number format: Omega serial number: 8-digit number on the caseback or between the lugs (on older models). Since ~2018 engraved on the caseback at 6 o'clock. Format: purely numeric. Verifiable on the Omega website with an extract from the archive.
