CASE Case in very good overall condition with light surfaces scratches and wear consistent with the age of the timepiece. In our view, the watch appears to have possibly seen one very light polishing in its past, still maintaining excellent proportions and thick lugs. There is some scratching underneath the lugs due to bracelet removal. The hallmark found beneath the top right lug is deep. The buckle displays scuffing and signs of wear, and is most likely not original to the watch. DIAL The dial is in good overall condition with damage to the outer rim spanning from 7 o'clock to 8 o'clock. The luminous hour markers have aged to a lovely shade of caramel. The seconds and 24 hour hand are replaced. MOVEMENT Movement number is 98044. The movement is running at time of cataloging, however it was not tested for the accuracy of time or duration of the power reserve and may need service at the buyer's discretion. Please note that Sotheby's does not guarantee the future working of the movement. ***Please be advised that the bands on this watch are made of materials derived from endangered or otherwise protected species (i.e. alligator and crocodile) and thus not sold with the watch, they are for display purposes only. We will remove these bands prior to international shipping.***

The present GMT-Master is a rare and early variant of the model, distinguished by the lack of crown guards on the case.  As the successor to reference 6542, the present reference 1675 features a rare transitional case with a matte brown dial and updated metal insert bezel.
