Omega Speedmaster vintage “Long S” dial ref. 3590.50 beautiful patina

Very nice Omega Speedmaster vintage ref. 3590.50 (ST 145022).

This example is 100% original, with its “long S and R” dial typical of the late 1980’s.  The tritium indexes have developed a beautiful cream patina.

The bezel sometimes has blue reflections depending on the light, which is really attractive.

The movement has been fully serviced.
