Details & Specifications
Description
The Omega Seamaster 600 ref. 135.011 is a mid-1960s gentleman's manual-wind watch that occupies a fascinating position in Omega's vintage catalogue — robust enough to carry the Seamaster name, refined enough to wear as an everyday dress watch, and characterful enough to reward the collector who takes the time to seek it out.
Produced around 1965, the reference sits within the Seamaster 600 family, so named for the line's 60-metre water resistance rating — a meaningful specification for a watch of this period. The black dial with Arabic numerals is a particularly striking configuration: clean, high-contrast, and legible in a way that the more common silver-dialled examples simply cannot match, with luminous applied indices and steel hands that complete a purposeful, instrument-like presentation.
The 34mm stainless steel case is slim and well-proportioned, measuring 40mm lug-to-lug, and wears with the understated confidence of the best 1960s Swiss watchmaking. The plexiglass crystal imparts the warm, organic quality that defines vintage watches of the era and is entirely appropriate to the piece. Powering the watch is the Omega Calibre 601, a reliable 17-jewel manual-wind movement of proven pedigree — wound daily, it offers an intimate, tactile connection to the mechanics within that no automatic can replicate. An honest, beautifully-dialled piece of 1960s Omega for the collector who values character over spectacle.
