Omega Seamaster Diver 300M 210.30.42.20.01.005 (“Monochrome” Black) — History
Origins & Context
The Seamaster Diver 300M line debuted in 1993, and over the decades it’s become one of Omega’s most recognizable tool/diver watch families. The 300M has had many evolutions in bezel materials, dials, bracelet styles, and movements.
The 210.30.42.20.01.005 represents a recent wave of updates. Part of Omega’s push toward clean, modern diver watches, it embraces contemporary technical materials and movement certifications while dialing back on some of the flash for a more monochrome, pared-down aesthetic.
Introduction of the Model
This “Monochrome” Black version was introduced around 2024-2025. It is notable for being one of the no-date versions of the 300M line, which is a departure from many previous models that had prominent date windows. It also comes in a mesh (or steel bracelet) option, which enhances its vintage tool-watch vibe.
