Rolex GMT Master 'Pepsi' 16750 40mm 1982 Case and Bracelet This previously polished Rolex GMT-Master ref. 16750, 40 mm, presents in great condition for its age. The stainless steel case retains well defined lugs and even brushing, with light hairlines visible in normal light and no dents or deep marks noted. The bidirectional bezel turns cleanly; the red and blue insert shows an attractive fade. The acrylic crystal is clear and free of distracting scratches. The oyster bracelet shows little stretch as expected with age, links articulate smoothly and the clasp closes securely.
