I think they don’t know why they wear them other than maybe they think its elevates their importance. If they were to wash their hands and dry thoroughly this would minimise fingerprints. Agree badly manicure fingers offers no aesthetic! But I’ll keep my eye on the watch. It is all opinion of course. 

I don’t mind a little (quick) bit of history especially when pertaining to some particularly  notable history as with the Cartier Santos. What does grate me, a lot, EVERY time, is people wearing silly gloves to handle a watch! increasing the risk of dropping it, protecting it from literally nothing (it isn’t ancient paper scrolls) and generally being distracting. Its like an appendage in a sock flapping about a watch face. Just stupid. I have even seen one glove on and one glove off!! 

Second to the glove wearers are those who literally get nothing right when discussing anything about the watch they are talking about, like they make it up. Closely followed by those with silly music.
