The Omega Chronostop Genève Ref. ST146.100 is a fascinating chapter in Omega’s sports timing heritage. Introduced in the late 1960s, the Chronostop was designed for dynamic lifestyles and became famously associated with athletic disciplines such as the modern pentathlon, where timing precision is critical across multiple events. Its unique “chronostop” function operates differently from a traditional chronograph: a single pusher starts timing when pressed, holds the elapsed time as long as it remains depressed, and instantly resets upon release. This design allowed athletes to take quick intermediate times without the need for complex chronograph operations, making it ideal for high-intensity competition.

This particular example is a true New Old Stock (NOS) time capsule from 1970, complete with original Omega guarantee, box, and untouched presentation. The case back still retains both the original factory wax seal and the protective sticker—details almost never seen today. Recently serviced for optimal performance, it combines fresh mechanical reliability with pristine vintage charm. The stainless-steel case, sharp edges, and flawless dial present exactly as they did over half a century ago, offering collectors the rare opportunity to own an Omega sports icon in as-new condition. A museum-worthy piece for the most demanding enthusiast.
