Speedmaster Professional 3572.50.00 “Hesalite Sandwich”

From $3,990

Around 1996, Omega phased out the reference 3592.50, and replaced it with the near identical reference 3572.50. The primary difference between the two watches was the movement that was fitted to them. The reference 3572.50 received Omega’s caliber 1863 movement, which ditched the golden-color of the caliber 863, and replaced it with rhodium finishing and Geneva stripes. 

This model was simply known as sapphire-back Speedmaster Professional watches; however many collectors now frequently refer them to as “Hesalite Sandwich” Speedmasters.
