Thanks for your advice; but of course everything is possible but who shall pay for that much work??
and if it would be so simple, why does tag-heuer dont offer such a job and does not give any garanty anymore ??

You should not go in the water with such a old watch anyway, would be a pitty if you kill it what way!!
Their where a lot of messages posted but heuer lovers with watch fell into water and got big damage!
think about it before you do any action.
greetings jasper
