A handsome triple cased watch made for the Turkish market, the outer case is unusually made of green-dyed ray skin, rather than the more traditional tortoiseshell covering. Interestingly, the movement pillars are crested Egyptian in design, such as one might expect to find at the beginning of the century, though very much smaller in size.
