The Speedmaster Professional Mark II was introduced in 1969. The shape of the case is seen nowadays as typical of the 1970s style, but the Mark II was one of the first watches to use that shape; other examples belonged to the automatic generation of Heuer Autavia. It was supposedly intended as an eventual replacement for the Moonwatch case, but the Apollo program had very tight schedules and the approval from the Test Division would have taken too much time for NASA.

The Speedmaster Mark Series consists of four distinct Marks. The first Mark, which is almost never referred to as the Mark I, is the original Omega Speedmaster Professional commonly referred to as the Moonwatch cal. 861.

This Omega Speedmaster Mark II is in very good vintage condition with a beautiful patina. Runs very accurate and comes with the Omega service box and Q-Watches GoldCard. The bracelet will fit a wrist up to 20cm. Lovely vintage Speedmaster!
