Omega Speedmaster 145.022 - ST 68 Transitional

The Omega Speedmaster reference 145.022 from 1968, known as the “transitional” Speedmaster, marks one of the most fascinating turning points in the history of the Moonwatch. The Speedmaster “ST68” sits at the crossroads between two eras — retaining much of the design language of the legendary Cal.321 models while introducing the new Caliber 861, a movement that would power Speedmasters for decades to come. Introduced in late 1968, this reference bridged Omega’s shift toward greater production efficiency and improved reliability, without compromising the rugged aesthetics that had already made the Speedmaster an icon of space exploration.

This example, with serial number 26.xxx.xxx, dates to 1968 and perfectly embodies that transitional spirit. It features the desirable stepped dial with applied Omega logo and long hour indices, maintaining the vintage depth and character collectors prize. Surrounding the dial is the early DON (Dot Over Ninety) bezel, a defining trait of pre-Moon Speedmasters, adding both historical and aesthetic value.

Under the hood beats the Caliber 861, introduced as the successor to the 321, offering a more modern cam-switched chronograph mechanism while remaining robust and precise. The watch is paired with its correct Omega 1116 bracelet with 575 end links, and retains its Omega logoed hesalite crystal, reinforcing its period correctness.

Accompanied by its Omega Extract from the Archives and original box, this transitional 145.022 is in beautiful, well-preserved condition — a cornerstone piece for any serious Speedmaster collection, representing the evolution from the pre-Moon to the Moonwatch era.
