Omega 210.30.42.20.06.001 (Pre-owned - Good) — USD 4,100 on eBay

The Omega Seamaster Diver 300M, reference 210.30.42.20.06.001, represents a significant evolution within Omega's celebrated Seamaster collection, building upon a legacy deeply intertwined with professional diving and cinematic heritage, particularly its association with James Bond. Introduced as part of the 2018 refresh, this reference modernizes the iconic Diver 300M line while preserving the core aesthetic that has defined it since its 1990s debut. It stands as a contemporary interpretation of a watch widely recognized for its robust functionality and enduring design. Encased in a 42 mm stainless steel chassis, the watch presents a striking grey dial, often featuring the laser-engraved wave pattern that became synonymous with the Seamaster Professional series. This detail, combined with the signature skeletonized hands and applied indices, contributes to excellent legibility in diverse conditions. A hallmark of the Diver 300M, a manually operated helium escape valve is integrated into the case at 10 o'clock, a critical feature for saturation divers. The unidirectional rotating bezel, typically ceramic, provides a precise timing instrument for underwater activities, complemented by an impressive 300-meter water resistance. Powering the reference 210.30.42.20.06.001 is Omega’s Caliber 8800, an automatic movement that underscores the brand's commitment to advanced horology. This METAS-certified Master Chronometer movement is equipped with Omega's revolutionary Co-Axial escapement, offering superior precision, stability, and durability. Its anti-magnetic properties, resisting fields up to 15,000 gauss, ensure reliable performance in an increasingly magnetized world. For collectors, this model signifies a harmonious blend of historical significance, contemporary design, and cutting-edge mechanical engineering, making it a highly desirable piece within the modern Seamaster Diver 300M lineage.
