Omega Seamaster 300M Green 210.30.42.20.10.001 'Seaweed'

Offered is the Omega Seamaster Diver 300M Green, ref. 210.30.42.20.10.001 - Omega's first green-dialed Diver 300M nicknamed 'Seaweed' by collectors. This is the steel-on-steel configuration with 42mm stainless steel case, green ceramic bezel with diving scale, domed scratch-resistant sapphire crystal with anti-reflective treatment on both sides, helium escape valve at 10 o'clock, and transparent caseback. The dial is the star - polished green ceramic with laser-engraved waves that shifts from deep forest to almost black in low light.
Powered by Omega's Co-Axial Master Chronometer Calibre 8800, automatic with 55-hour power reserve, 300m / 30 ATM water resistance, and METAS certified. At 42mm x 13.56mm it wears modern but balanced on the stainless steel bracelet with folding clasp. One of Omega's most visually commanding modern Seamasters - the all-green monochromatic look is bold without being excessive, inspired by the color of seaweed found in the depths of the ocean.
