Are there are any guidelines for the type of watch that should be worn with a certain outfit for men? For example, a digital sports watch (e.g.a Timex Ironman or a Polar heart rate monitor) does not exactly go with a suit.
I'm just looking for general guidelines regarding chronographs, metal watches, leather straps, etc. for these types of outfits:
Business formal (e.g suit and tie)
Business casual (e.g. buttoned-down shirt and khakis/dress pants)
Casual (e.g. polo shirt and jeans)
Summer (e.g. T-shirt and shorts)
I realize people will wear just about anything with anything, but I'm presuming there are some guidelines, right?
