Hi mate, yes I read the informatio, the Diver had been close properly, thanks for sharing
The diver's extension is a portion of the bracelet clasp that, when popped open, extends the length of the bracelet by 3.1 centimeters (about 1.25 inches). This allows it to instantly change from being sized to fit on your bare wrist to the larger size needed to fit over the sleeve of a wetsuit. While interesting, this is a feature that is of virtually no use to anyone who is not a wetsuit diver. Though it could be used to wear the watch on the outside of an elastic jacket cuff in cold weather.
One critical point to note when operating the diver's extension is to ensure you have closed it properly when done. The small [censored] on the extension must fit under the crossbar. Failure to close it properly can interfere with the main bracelet clasp--causing the clasp to pop open unexpectedly while you are wearing the watch.
thanks for the info my friend
