Omega speedmaster 145022 Patina from 1992

Omega Speedmaster Professional ref. 145.022 — 1992 Big-S Tritium Dial

There is something deeply honest about a Speedmaster that has earned its look. This Omega Speedmaster ref. 145.022 from 1992 comes as a head-only example with a beautifully aged tritium patina and the desirable “Big S” dial signature, a subtle but highly collectible detail from this era. The warm, creamy lume tones have developed evenly across the dial and hands, giving the watch a character that only decades of natural ageing can create. Fully serviced and mechanically crisp, this is a Moonwatch that wears its history proudly — authentic, soulful, and unmistakably Speedmaster.

Technical Background
This reference 145.022 is powered by Omega’s legendary calibre 861, the cam-lever chronograph movement that succeeded the Moon-qualified cal. 321 and became the backbone of the Speedmaster line for decades. Early-1990s examples with tritium “Big S” dials mark the final years before Luminova, making them especially sought after by collectors who value originality and correct period details.
