Roffle at cufflinks being stealth bling. Tie pins are for yuppies though.
I know rosaries shouldn't be worn round the neck, but if someone feels strongly enough about his faith to want to wear one then I can tolerate it.
Re watches... I don't wear one at all, and think they look bloody awful incongruous on women dressed up. Watch on your wedding day looks like you forgot to take it off, IMHO. That said, I don't have the same sneering feeling towards women's metal straps that I have towards men's. Silver can be very stylish if it is effectively a nice bracelet with a watch face.
