Omega · Family: Seamaster
The Omega Seamaster Diver 300M (ref. 210.30.42.20.01.001) is a current-catalog, 42mm stainless steel dive watch water-resistant to 300m, built around Omega's in-house Calibre 8800 — a Co-Axial Master Chronometer movement, METAS-certified, with roughly 55 hours of power reserve. Cazador has zero verified price observations. Its standout detail: the line's characteristic wave-pattern dial, paired with a black ceramic bezel, helium escape valve, and skeleton hands.

The reference 210.30.42.20.01.001 represents the current specification of Omega's Seamaster Diver 300M in stainless steel, built around the manufacture Calibre 8800 movement — a Co-Axial Master Chronometer caliber combining Omega's proprietary co-axial escapement with independent testing by METAS. METAS certification tests the fully cased movement and checks performance under exposure to magnetic fields, beyond standard COSC requirements.
At 42mm in stainless steel, the case carries a water resistance rating of 300 meters, backed by a helium escape valve — a fitting that lets helium molecules that seep into the case during long, deep dives vent safely during decompression. The crown is screw-down.
The unidirectional bezel is finished in black ceramic and carries a diving scale. The dial is finished in the wave pattern that has become a recognizable signature of the Seamaster Diver 300M line, combined with skeleton hands.
Calibre 8800 delivers approximately 55 hours of power reserve. As of this writing, the reference remains part of Omega's current catalog and in active production, with no discontinuation announced. No confirmed launch year for this specific reference was available in the source data.
Cazador has zero verified price observations for this reference, so we cannot publish a reliable market range.
It runs Omega's in-house Calibre 8800, a Co-Axial Master Chronometer movement certified by METAS, delivering approximately 55 hours of power reserve.
It is rated to 300 meters of water resistance, backed by a helium escape valve and screw-down crown.
The dial carries the wave pattern that has become a signature of the Seamaster Diver 300M line, combined with skeleton hands.
Yes. According to manufacturer catalog data, this reference remains part of Omega's current lineup and in active production.
This reference uses a black ceramic bezel insert with a diving scale. Ceramic resists scratching, UV fading, and corrosion better than aluminum inserts.
It lets helium molecules that seep into the case during long, deep saturation dives vent out safely during decompression, preventing pressure buildup against the crystal.
