1990 Omega Speedmaster 3590.50

Offered is a 1990 Omega Speedmaster Professional Moonwatch, ref. 3590.50 / ST 145.0022 - the last of the true vintage Moonwatch era before the modern 3570.50 transition. Circa 1990 with 48.2 million serial, this is the desirable tritium dial configuration with tall closed S dial and wide C tachymeter bezel, 42mm stainless steel lyre lug case, original acrylic crystal with Omega logo in the center, black aluminum tachymeter bezel, and matte black dial with three registers and tritium hour markers that age beautifully.
Powered by the legendary hand-wound Caliber 861, 17 jewels, 48-hour power reserve - the direct descendant of the moon caliber. Originally delivered on Omega bracelet 1479/812, this is the last generation with that classic low-profile Moonwatch case, hesalite look, and pre-Superluminova warmth. A collector favorite for its transitional details - not quite vintage 145.022, not yet the modern sapphire sandwich - pure Moonwatch DNA from the year that defined modern Speedmaster collecting.
