WatchOtaku : Diver extension

A diver's extension is so that a bracelet can be made longer without tools, so that a dive watch can be worn over a wetsuit. There are two major types, fixed length or adjustable. Here's fixed length extension from my Halios Holotype:

The silver slider on the clasp releases the extension while still on the wrist. Clever and comfortable, and nice on hot days when wrists enlarge.

Here's the fixed-length one on the Seiko Monster:
