1974 Omega Speedmaster Moonwatch ref. 145.022-71 “Step Dial”

Up for grabs is an Omega Speedmaster Moonwatch

145.022-71 reference

328440XX serial number, which falls correctly into a watch features a -71 caseback still. Production in 1974.

Excellent vintage condition case with no corrosion or pitting or major dings/dents.

Dial is original, step, in excellent vintage condition. Up close, you can see even spotting throughout, though the luminous material is nicely patina’d, so I wouldn’t say its moisture spots.

Bezel is in excellent vintage condition with minor signs of wear.

Caseback is original, stamped 145.022-71 inside with crisp outer engraving.

This watch also came on an Omega 1039/516 flat link bracelet. Its dated in 1967, so I wouldn’t say it was born for this watch, but added at some point later.

No box or papers. No service history is known, but the watch winds smoothly, shows +7 seconds with ~250 amplitude.
