What to do for a flooded Sub?

[8850]

Last week I went in to my local AD to have my 15yo sub pressure tested as I was going scuba diving in the caribbean. The AD completed the pressure testing and replaced the gasket without any issue. Today, after diving in relatively shallow water I noticed that the watch was completely flooded with water and, obviously, not running. I'm on the island for the next 7 days and while there is a dealer here there is not service. I have sent e-mails to the servicing AD but they are closed on Sunday.

Anyone got any ideas on how to get the water out? I don't want to try and open anything myself without the consent of the servicing AD as I hope they will be good enough to help out when I can reach them.

Thanks for the advice.
