Overview
The Omega Seamaster Diver 300M Co-Axial Master Chronometer reference 210.30.42.20.06.001 represents the thoroughly modernised generation of Omega's iconic diving line, introduced in 2018. Its 42 mm stainless steel case houses the in-house Calibre 8800, certified to the stringent Master Chronometer standard by the Swiss Federal Institute of Metrology (METAS). The grey ceramic dial, rendered with Omega's signature wave pattern, anchors the watch firmly in the Seamaster's long visual heritage while embracing contemporary materials.
History
The Seamaster Diver 300M line traces its roots to 1993, when Omega relaunched the Diver 300M as a modern sports watch that would go on to gain wide recognition through its association with the James Bond film franchise. The 2018 generation marked a decisive technical step forward, replacing the earlier Co-Axial movement with the new Calibre 8800 and elevating the certification level to METAS Master Chronometer. The grey ceramic dial variant sits within a broad palette of dial options introduced across the 2018 collection, appealing to collectors who favour a more restrained, contemporary aesthetic over the traditional blue or black.
Notable points
- Calibre 8800 is certified as a Master Chronometer, meeting METAS standards for accuracy, magnetic resistance up to 15,000 gauss, and overall performance across eight tests.
- The dial is crafted from grey ceramic, offering superior scratch resistance and long-term colour stability compared to conventional lacquered or enamel dials.
- The wave-pattern texture on the dial is a defining visual signature of the Seamaster Diver 300M line, carried across generations since the 1990s.
- The Co-Axial escapement, developed by George Daniels and adopted by Omega, reduces friction in the gear train and extends service intervals relative to traditional lever escapements.
- Water resistance is rated to 300 metres, consistent with the model's professional diving heritage.
