Omega Speedmaster Professional Moonwatch | Hesalite Sandwich | Ref. 3572.50

The Omega Speedmaster Professional Moonwatch Ref. 3572.50 is a highly desirable neo-vintage Speedmaster that combines the traditional appearance of the classic Moonwatch with the mechanical appeal of an exhibition caseback. Produced from approximately 1996 through 2002, this reference features a 42mm stainless steel case, matte black dial, black tachymeter bezel, Hesalite front crystal, and stainless steel bracelet.

The beauty of the 3572.50 is its unique “Hesalite Sandwich” configuration. From the front, the watch maintains the warm appearance and subtle distortion of a traditional Hesalite Moonwatch. On the reverse, a sapphire exhibition caseback provides a clear view of the manually wound Omega Calibre 1863. This gives collectors the classic Moonwatch experience while allowing the decorated mechanical movement to remain visible.

The black dial features luminous hour markers, white baton hands, and the classic three-register chronograph layout, including a small-seconds display, 30-minute counter, and 12-hour counter. Powered by the manually wound Calibre 1863, the watch offers an approximately 48-hour power reserve. Its relatively short production period, discontinued configuration, and balance of vintage-inspired design with an exhibition caseback make the 3572.50 a particularly appealing Speedmaster for collectors.

Condition

Please review the photos carefully for an accurate representation. Light scratches, bracelet wear, bezel wear, Hesalite crystal wear, or other signs of use consistent with age may be present and do not affect functionality. The watch presents well overall with expected wear for its age.
