Own a ZF Tudor Black Bay it has come in contact with a small amount of water, a splash on the crystal .Obviously as waterproof as a sponge ( That's why i laugh when i read threads , just purchased an Arf Submariner can i take it diving LOL) . The water was quickly wiped off , however have now noticed a have a small amount of condensation under the crystal . Anybody got suggestions on how to clear ? Many thanks in advance ?
