OMEGA lists a 42 mm case, 300 m water resistance and a 55-hour power reserve. Its Japanese regional listing shows ¥990,000; that is not a U.S. price. This guide identifies the exact configuration, summarizes the manufacturer’s specifications and explains what the available price evidence does—and does not—tell buyers.
Which green Seamaster Diver 300M is this?
The title refers to the green dial and green ceramic bezel model on a stainless-steel bracelet: 210.30.42.20.10.001. OMEGA’s Hong Kong product description specifies a polished green ceramic dial with laser-engraved waves, a date window at six, and a green ceramic bezel with a white enamel diving scale.
There is also a green version on a rubber strap, reference 210.32.42.20.10.001. It is a separate configuration, not the bracelet reference with a strap substituted in a price listing. Confirm the exact reference and attachment system before buying a replacement strap; a nominal 20 mm width alone does not establish compatibility.
What are the specifications?
The figures below are manufacturer specifications for the bracelet reference, not measurements from an independent hands-on test. OMEGA Japan describes the crystal as domed sapphire with anti-reflective treatment on both sides, and identifies the movement as Master Chronometer-certified.

The 42 mm diameter is only one part of wrist fit: the listed 49.93 mm length and 13.56 mm thickness also affect how the watch sits. If possible, try it on or compare those dimensions with a watch you already know fits well. The stated water resistance is a manufacturer rating; it is not a recommendation to use a particular watch for a specific activity without observing OMEGA’s care and operating guidance.
What is the price?
OMEGA Japan’s regional product listing displays ¥990,000 for the steel-bracelet reference. The same listing shows ¥935,000 for the related green rubber-strap configuration. These are Japanese regional prices, not U.S. MSRP or a global price; the listing evidence does not establish tax treatment, stock at a particular seller, or a current U.S. price. Prices, taxes and availability can differ by market and change over time.

A 2022 hands-on review covers the green model and identifies the bracelet reference, but its launch-era pricing is historical and should not be treated as today’s asking price. Check the current local OMEGA listing or an authorized retailer for the price applicable to your market.

OMEGA announced a different new Diver 300M range on 21 November 2024, saying its new 42 mm choices drew inspiration from the 007 Edition and used domed sapphire crystals. That announcement concerns a later range; it does not, by itself, establish that reference 210.30.42.20.10.001 was redesigned or discontinued. Treat the green ceramic bracelet watch as its own exact reference when checking listings.
