I've just recently started maintaining my own watches, but my Pierre Cardin 3738 is presenting a problem with the bracelet. It was my first good watch and I've had it for 10 years now. It is filthy and scratched and I'm trying my hand at cleaning and polishing it. I've got an ultrasonic bath, but no idea how to detach the bracelet. All the guides online say to get between the lugs, but I don't have any (or at least not the traditional kind). The pins in the side of the band don't respond to a pin-push either. Please help!
