Overview
The Omega Seamaster Diver 300M Co-Axial Master Chronometer in reference 210.20.42.20.01.001 pairs a 42 mm stainless steel and yellow-gold two-tone case with a striking black ceramic dial rendered in Omega's signature wave pattern. Powering the watch is Calibre 8800, a movement certified to the stringent Master Chronometer standard by the Swiss Federal Institute of Metrology (METAS). The combination places the piece at the intersection of the Seamaster's long diving heritage and Omega's contemporary movement technology.
History
The Seamaster Diver 300M line traces its roots to 1993, when Omega relaunched the Diver 300M as a modern professional dive watch that would go on to achieve broad cultural recognition. The current generation, introduced in 2018, brought a comprehensive redesign encompassing ceramic dials, the Co-Axial Master Chronometer movement architecture, and improved water resistance. The two-tone steel-and-gold configuration continues a tradition of offering the Diver 300M in precious-metal and mixed-material variants, appealing to collectors who seek a dressier expression of the tool-watch form.
Notable points
- Black ceramic dial: the wave-pattern surface is executed in ceramic, offering superior scratch resistance and long-term colour stability compared with traditional lacquered dials.
- Calibre 8800: a Co-Axial escapement movement certified as a Master Chronometer, meeting METAS requirements for accuracy, magnetic resistance up to 15,000 gauss, and power-reserve performance.
- Two-tone construction: the 42 mm case combines stainless steel with yellow-gold elements, bridging the Diver 300M's tool-watch origins with a more formal aesthetic.
- 300-metre water resistance: the reference retains the full professional dive specification of the Diver 300M line, including a unidirectional rotating bezel.
- 2018 generation redesign: the current Diver 300M introduced a slimmer profile, ceramic bezels, and the Master Chronometer movement standard across the collection.
