Housed in a round 42mm stainless steel case with a transparent case back, this Speedmaster Professional features a black dial and a black bezel bearing a tachymetric scale. A scratch-resistant sapphire crystal protects the face, and the watch carries a water resistance rating of 50 metres / 167 feet. Lug width measures 20mm, accommodating the included brown leather strap.
Powering the watch is the hand-wound Calibre 1863, a COSC-certified mechanical movement that drives the chronograph complication the Speedmaster has carried for decades. The transparent case back allows a direct view of the movement in action.
This pre-owned example is offered with its original box and papers, making it a well-documented example of one of Omega's most recognized references.
