Product Description
Available is an Omega Speedmaster Automatic, reference 3511.50.00, featuring the striking “Reverse Panda” dial configuration black base with contrasting silver sub-registers and date display at 3 o’clock. Part of the Speedmaster Reduced family, this model combines the hallmark design language of the Moonwatch with compact, everyday versatility in a 39 mm case.
Powered by the Omega Calibre 1152 automatic chronograph movement (ETA 7750 base), the watch delivers smooth timekeeping and precise chronograph performance. This example remains in very good pre-owned condition, showing light wear on the bezel, case, bracelet, and clasp consistent with careful use. The stainless-steel surfaces retain sharp factory geometry and attractive polish throughout. The bracelet is fully linked and comfortably fits wrists up to 7.5 inches.
The crystal has been replaced with an aftermarket sapphire unit (Omega logo not etched at center). Offered as a watch-only set.
A collectible and versatile entry into the Speedmaster lineage balancing Omega’s chronograph heritage with classic proportions and vintage appeal.
