What Makes the Seamaster Special:
The Omega Seamaster traces its roots back to 1948, making it the oldest continuous line in the manufacture's catalogue. Originally derived from waterproof military timepieces delivered to the British Ministry of Defence during World War II, the Seamaster evolved into a professional diving standard with the launch of the Seamaster 300 in 1957 and the iconic Diver 300M in 1993. To honor 75 years of maritime legacy, Omega unveiled the "Summer Blue" collection, utilizing varying depth shades of blue across the dial spectrum to reflect each model's water resistance level.
The reference 210.30.42.20.03.003 features a layered dial that transitions from a lighter central hue to a deep navy perimeter, mirroring the way sunlight filters through ocean water at 300 meters. The signature laser-etched wave motif is rendered with exceptional depth, complemented by a blue ceramic bezel with a matching light-blue enamel diving scale. Flipping the watch reveals a commemorative solid caseback engraved with an artfully sculpted Poseidon driving two seahorses—a tribute to Omega's maritime heritage.
At its core, the watch is driven by the manufacture Calibre 8800 automatic movement. Tested and certified by METAS as a Master Chronometer, it provides exceptional resistance to magnetic fields up to 15,000 Gauss while maintaining chronometric precision under extreme temperatures and pressures. Featuring an integrated fold-over clasp with an expandable diver's extension, this 75th Anniversary model represents an outstanding blend of modern mechanical mastery and milestone heritage design.
