1968 Omega Speedmaster Pre-Moon 145.012 - Serviced cal. 321, Display Back

Not in stock


This really is a very unique Pre-Moon Speedmaster as we have never seen anything alike it before. Back in 2001 a cal. 321 enthusiast had the movement completely plated with a silver metal and for it to be seen, he had the original caseback transformed into a sapphire display caseback. We have not found out what metal was used but the plating was exquisitely done and it still looks perfect. The dust cover was turned into a movement holding ring, so the movement can be seen and still holds in place. In order to wear it water tight, the watch comes with an additional new 145.0012 service caseback.

As for the rest, the watch is original in all of its parts with a nice "spaced T" applied logo dial, DON bezel, drop chrono second hand and hesalite crystal.
