No, it’s not. Under no circumstances should you follow my lead and jump into the river with it still on. Neither should you go for another shower only to realise in a frustrated panic that you did it again. Our watches should be able to handle a few drops of water here and there, but if that happens, wipe off any residual moisture with something absorbent and leave them in the sun until any remnant water marks have disappeared. If your watch isn’t dried immediately, the wood may retain that water, expand and later crack. Wooden watches can be susceptible to cracking, as they are often cut pretty thin in places, so care should be taken to avoid getting them wet.
