Turn-ons: big (44mm and up, the bigger the better) round/square/rectangular on leather, metal. Not blingy, or very little. Inside or outside, not loose.
Turn-offs: small watches, digital, sports .... these can actually classify as major turn-offs.
Great finds man! However, you think maybe those Apple watches can get a topic/thread of their own? There seems to be enough material out there to warrant that.
