Up for grabs is an Omega Speedmaster Perpetual Calendar
Reference BA 175.0037 (PIC 3650.10)
This watch was produced in 1991 in only 50 examples made to commemorate the 700th Anniversary of Switzerland. This was and still remains the most complicated Speedmaster Omega has every produced. This model was exclusive for the Japanese market only.
The case is 39mm with Cal. 1160 inside. Very sharp and mint condition remains unpolished.
The caseback is damage-free with very crisp commemorative markings.
The watch comes on unworn leather strap with original solid gold Omega buckle. A genuine Omega brown strap will also be included with the sale. The same one as would come on this watch originally.
No boxes or papers. The watch runs and functions as it should.
