Please scroll down for photos...

The watch is in decent shape, with light scuffing on bracelet, and one light scratch on the crystal which can be sort of seen at 1 o'clock in the last photo. The bracelet fits an 8 inch or smaller wrist.

The dial is the star of the show here! I hand engraved the shark, the diver, the diver-down flag and the entire minute track into the mother of pearl. The engraving was filled with calligraphy ink, the exes wiped away. A light coat of laquer was applied as a final sealant over the whole dial. This process is an old technique called scrimshaw, and was practiced by sailors of old wiling away their time on their off watch.
It is a one of one dial, meaning it's the only one like it (I don't think I could reproduce it if I wanted to), and it is very well executed. It took me about 10 hours to make it....

Shipping within the USA is included in the price, and so is paperwork on the dial.
