1989 Omega Speedmaster Moonwatch ref. 3590.50 “Long R, 1450 Bracelet”

Up for grabs is an Omega Speedmaster Professional Moon Watch

3590.50.00 reference with caliber 861 movement

482509XX serial number circa 1989 before Omega started engraving the serial number underneath the lug.

Excellent vintage condition watch with minor signs of wear and age. Probably unpolished.

Dial is original, tritium with nice patina. Damage free. Original tritium hands. This is also the end of the “Long R” dials in Speedmaster

Caseback is excellent and stamped ST 145022

Crystal is hesalite Omega with logo in center.

Bracelet is original Omega 1450 which was only in production for about 4 years. It fits a small wrist and also the clasp has been replaced with 1469 clasp during past repair.

I don’t have documented service history, but previous owner said it was serviced within the past year and the watch currently runs well at +1 secs per day with ~310 amplitude.
