I'm going with the AP 5279 caliber 2120.... again. It keeps jumping onto my wrist whenever it matches the colors of the day's outfit. There's an IWC and a Longines that are getting very jealous. Here's why it's my favorite:
I'm still slightly too fat to fit into it at the moment, but I'm wearing it until my hand turns bright read and goes numb.
Couldn't resist the call of the Flagship caliber 341 even though it's only getting a couple hours of wrist time tonight.
