Omega Speedmaster Reduced Chrono 178.0055 39mm (2000)

A more compact take on an iconic design, the Omega Speedmaster Reduced Chronograph Ref. 178.0055 delivers classic Speedmaster styling in a versatile 39 mm stainless steel case. Designed for those who love the Speedmaster heritage but prefer a slightly smaller profile, this model retains the spirit of the legendary Moonwatch while offering everyday wearability.

The black dial features the signature tri-compax chronograph layout, with applied hour markers, luminous hands, and a crisp white minute track for enhanced legibility. The black aluminium tachymeter bezel adds a sporty edge, while the domed hesalite crystal gives it that vintage-inspired charm.

Inside beats an automatic chronograph movement (Omega Calibre 1140), based on the ETA 2890-A2 with a Dubois-Dépraz chronograph module—offering dependable performance and smooth operation. This reference is fitted with a solid stainless steel bracelet, providing a seamless and comfortable fit. Compact, stylish, and unmistakably Speedmaster — the Reduced Chronograph 178.0055 is a classic choice for those who want Omega’s chronograph legacy in a refined, wearable size.

Please note, this watch comes with its original box but only has service papers from the Omega brand.
