145.022 straight writing

Produced in 1970

This was Omega’s first response to the Speedmaster’s involvement in 1969 Moon landings. There are actually three different versions. These are rare, and now the market has responded and values them higher than a -69. The “Flight Qualified”case back is also replicated in a service case back, easily identified by the longer case back slots. The “Apollo XI”case back is much rarer, and if two collectors see it, they will fight hard for it.

All three executions of the straight writing case back. On the left is the more common 1970’s back, in the middle is the rare “Apollo XI” and on the right is the NOS purchased by me last year via Omega as a service part.
The rarest straight writing case back, with “Apollo XI”
A rare example of a “Full Set”. Box and Papers. 145.022-69 Transitional back

I would expect this reference to carry the DN90 bezel.
