Offering up a really nice fully serviced 1990s Omega Speedmaster tritium dial 3590.50.

The serial is 48,27xx,xxx so is most likely c. 1991.

The movement has been serviced by Simon Freese watchmakers in April 2023, with all functions working as expected.

The watch is in very good condition and the dial and hands have that great yellow tritium patina seen with this reference. The case is still very sharp and appears unpolished, with a few marks commensurate with the watches 35 year old age. It comes on a 1479/812 bracelet that fits my ~7.5” wrist with extra links provided (should probably fit up to ~8” with the extra links).

Overall I think a really nice serviced Speedmaster at a reasonable price. All photos are from the last few days with exception of the movement photo, which was taken at service.

No buyers remorse refunds, refunds made only if the watch has been inaccurately described.

$4,300 USD including shipping within the United States. Shipping internationally to be discussed.

I’ve bought and sold several watches from the forum over the years with references available on the forum.

Detailed specifics of the watch from

-Crystal: Type A5 No logo (“The version without a logo has been seen on the ST345.0808 models of the 1980s and 1990s and on the ST345.0809 with moonphases. It also seems to include the reference ST 145.0022 of the same period.)
