Omega Seamaster Diver 300M homages

For a Diver 300M-style watch, decide whether you want steel automatic, titanium quartz or titanium automatic before choosing a dial. The OCT004 black ceramic is steel with a PT5000. The Watchdives WD007Q V2 blue uses VH31 quartz, while the WD007 V4 white and blue uses a PT5000. Each follows the Diver 300M look rather than one Omega reference.

Seamaster is a wider name. This page covers the Diver 300M; the Seamaster 300, Aqua Terra and Planet Ocean have their own pages and their own specifications.

The two original product sheets both name 42 mm cases and Omega 8806 with 55 hours of reserve. Nekton has a steel case, black dial and steel bracelet. The 007 Edition has a titanium case, brown dial and titanium bracelet. Their lug-to-lug and thickness values differ, so there is no single 42 mm Diver 300M measurement set.

Omega calls the 007 Edition the watch from No Time To Die and describes its dial and aluminium bezel ring as brown and tropical. A blue wave dial sold with NTTD in its name changes that design. The name is a starting point, not a match to the reference.

Watchdives says the WD007Q V2's VH31 seconds hand moves four times per second. That description does not make it an automatic movement. Its quartz operation is a different buying choice from OCT004's PT5000 automatic and Omega's self-winding 8806.

The WD007 V4 is a separate automatic line. Watchdives fits the PT5000 to the white-dial, blue-bezel option, and other dials can come with the Peacock SL3001. Check the movement and bracelet of the exact option a seller offers.

The OCT004 maker page gives 42 mm across without the crown. Watchdives labels the WD007Q V2's 42 mm as the bezel, so its case width is left blank here.

Octopus lists the OCT004 at 49.5 mm lug to lug and 14 mm thick including the crystal. Watchdives lists the WD007Q V2 at 49.3 mm and 12.3 mm. On these figures the OCT004 is about 1.7 mm thicker.

Watchdives gives the WD007 V4 as 42 mm across without the crown, 48.95 mm lug to lug and 12.2 mm thick including the domed crystal. Those figures belong to the V4, not the WD007Q V2 or an earlier generation.

Omega states 300 m for both original references. Watchdives states 200 m for the V2 quartz and V4 automatic lines. Octopus's page says both 200 m and 300 m, so the OCT004 gets neither here. No figure on this page is a pressure test of the watch you receive.

The catalogue includes the Pagani PD-1667, which follows the 007 Edition itself, but its listing leaves the movement and version unclear. It stays out of the shortlist until those are known.
