Years of evolution of one of the most significant watches in history led the Speedmaster Mark series to this point. The ultimate in Speedmaster functionality and legibility; the Mark 4.5 is one of the last Speedmasters sold while the model was still proffered as a technical instrument and a bonafide tool. This great example comes with a rare and original Holzer bracelet, which is is fantastic condition.

Inside, the 4.5 is powered by the venerable Omega Automatic Cal. 1045 - the Omega Calibre based on the Lemania 5100. On the wrist it rewards the wearer with a surprisingly supple and tactile chronograph pusher feel and impressive, but not dominant wrist presence. It’s worth noting that the date and day function is seen here in Spanish.
