I suppose the answer has to be ... it depends if it's waterproof or not.
Or, I could have answered "Yes, I always wear a diving watch, fnaar fnaar" or something like "Only if it matches the Batman outfit" or even "No, the chickens tend to be scared by the ticking".
I could have made onanism jokes like "Only if they need winding, then I wear three on my right wrist" or "No, the ticking might wake her up".
Even worse, I could have made a paedo joke like "Yes, the kids love my Mickey Mouse dial" or an adultery one like "Of course, I need to know when her husband will be back" but no, people have to mention practical matters like diamond vs sapphire.
An interesting thread, for sure.
