Seamaster 300 Heritage 41mm Black Sandwich Dial | Ref. 234.30.41.21.01.001 | 2022 Full Set

The Story

In 1957, Omega introduced a trilogy of professional timepieces that would forever alter the landscape of horology: the Speedmaster, the Railmaster, and the Seamaster 300. Designed specifically for divers and underwater professionals, the original reference CK2913 established a benchmark for legibility and aquatic durability. The Seamaster 300 Heritage (Ref. 234.30.41.21.01.001) represents the ultimate modern evolution of that legacy. By stripping away modern crown guards and bulky ceramic bezels in favor of clean vintage geometry, it delivers an intensely charismatic, historical statement piece tailored for the collector who demands authentic heritage soul backed by bulletproof Master Chronometer performance.

The Craft: Sandwich Dial Architecture & METAS Calibre 8912

The 41mm stainless steel case showcases refined vintage ergonomics, featuring slender twisted lyre lugs, a thin bezel profile, and alternating satin-brushed case flanks and mirror-polished surfaces.

The black dial utilizes an authentic "sandwich" construction, where the upper dial plate features cut-out Arabic numerals and triangular markers, revealing a lower plate drenched in vintage-toned Super-LumiNova. This gives the dial a mesmerizing three-dimensional depth. The hands pay homage to the 1957 original with the classic "Broad Arrow" hour hand and a smooth "Lollipop" central seconds hand.

Turn the watch over to admire the mechanical engine through the sapphire exhibition caseback: the In-house Co-Axial Master Chronometer Calibre 8912. Free from a date window to preserve 100% dial symmetry, this twin-barrel automatic movement is certified by METAS (the Swiss Federal Institute of Metrology). It provides a smooth 60-hour power reserve, complete immunity to magnetic fields exceeding 15,000 gauss, and a time-zone function allowing the hour hand to be adjusted independently without stopping the watch. Supported by a screw-down crown, it delivers a professional rating of 300 meters (1,000 feet) of water resistance.
