Sea water leakage to a Rolex - what to do ?

[mg1953]

I have a question, for which am curious to find an answer:

Suppose you are in Maldives, enjoying blue sea and sun. You forget to lock the crown of your Rolex, and you observe that sea water has leaked into the watch.

There is no RSA at the holiday spot and the earliest time for your return home is one week.

Which is the right action to keep the watch safe until you take it to your Rolex service in your town ?
