William Holme Twentyman (31 October 1802 – 7 May 1884) was a silversmith in Cape Town, who amassed a considerable fortune on Mauritius and retired at the age of 39. Whilst on Mauritius he created a sealed case for a pocket watch to be worn under water. After trials soldered lugs were incorporated and a "strong canvas" band was tied to the wrist for ease of use. Twentyman also painted the dial orange as to be more clearly seen underwater. This creation was known as the Twentyman "orange gorilla" due to its large size.
