Hello tinbum, to RepGeek

Good advice above, don't bother with the waterproofing, it probably won't be done anyway. Some reps are highly water resistant because they're good copies of the very water resistant gens. i.e Rolex Submariner, Sea-Dweller, Breitling Steelfish. etc.
Other reps will never be very water resistant no matter what you do to them (all chrono watches).


Enjoy your stay
