Did you acquire your bracelet from a boutique? If so, did they offer to exchange or refund your purchase?
Something must be off, because the Speedmaster lug width has been constant at 20mm following the introduction of the 105.012 case reference, and all 20mm endlonks, beginning with 16, 516, 633, and onward are interchangeable with the case. They are all 20mm, and designed to work with the Speedmaster Professional case. In fact, the 1171/633 is also the bracelet for the 20mm Seamaster 300 165.024 cases.
Any other comparable experiences from OF family members, either positive or negative with an 1171/633 bracelet on their ST?
