Drawing inspiration from the storied first-generation Speedmaster, this 41.5mm round stainless steel case houses a silver dial behind an anti-reflective, scratch-resistant sapphire crystal. A fixed bezel frames the dial, while a transparent case back invites a view of the movement within. Water resistance is rated to 100m/330ft.
At its heart beats an automatic Co-Axial chronometer movement that has earned COSC certification, confirming its precision to the rigorous standards of an independent timing authority. The chronograph complication is the centrepiece function, expressed cleanly across the silver dial.
The stainless steel bracelet features a brushed and polished finish and secures via a push-button folding clasp. Reference 331.10.42.51.02.002 is listed in new/unworn condition, with a case thickness of 16.5mm rounding out the key specifications of this classic-inspired sports chronograph.
