Omega Speedmaster vintage ref. 145.022 CRS circa 1981 unpolished

Very nice Omega Speedmaster vintage ref. 145.022.  It has been produced in 1981 according to its serial number.

The case has never been polished, which is quite rare.  The lugs are still thick and sharp.

The caseback is stamped CRS, an abbreviation for C.-R. Spillmann et Cie, which manufactured Speedmaster cases between 1981 and 1987.

Original “Long S and R” dial.  The tritium indexes and hands have developed a very nice patina.

Original “B2” bezel with the writing “TACHYMETRE” in big characters without accent.  It is in perfect condition.

The watch is fitted with its original steel bracelet ref. 1171/633.

The movement has been checked and tested.
