This is my first Patek Philippe wristwatch (Ref 3760), and would appreciate any information. This has a cal 177 movement stepped rectangular case. 18 kt yellow gold, with an aftermarket PP band with 18kt yg buckle and tang. I've been told this is from the 80's, I'll try to send photos once I figure out how?? I'm new to this, and trying to figure this out (lol).....
Any info will help, this is my first Patek.
