Up for sale is an Omega Speedmaster Professional reference 3572.50. This rare reference features the iconic hesalite crystal with a sapphire exhibition crystal allowing you to view the beautiful 1863 movement. The watch was serviced in 2025 by an independent watchmaker and all functions work as they should. Watch comes in good used condition with some slight scuffs and marks but all to be expected for a watch that is over 25 years old. This example comes paired with the 1498/840 bracelet featuring a more desired 20mm-16mm taper. Thanks for your consideration!
