The last and the first…
This reference Speedmaster is the last reference with step dial and is the first with the Speedmaster medallion in the center of the caseback. Production started in 1971 and was produced alongside reference 145.0522-69.
In the 70s the production of different references at the same time was no exception. In 1972 and 1973 no case backs were produced, so you can find ref. 145.022-71 until at least 1974. Some say up till 1976. This example comes on an olive green suede strap this emphasizes the beautiful patina of the tritium. ( if you like another color or material, the choice is yours).
If you see this Speedmaster it is obvious that this has gone places. It had a life already but it is ready for its second life….Are you?
