Ranthony...er...Anthony...what you do is borrow the watch and tell "Rick" that while you were doing charity work unloading food and medicine parcels on the docks, you were jumped by 17-18 armed men who stole the watch.
Possible answers to questions:
1. You needed a 100K watch to do charity work because you really believed in this project but it was for only hideously rich people to pay back to the community they've stepped on all these years and you needed to fit in.
2. You don't have a bruise or a mark on you and didn't fire a shot in return because the armed gang threatened to shoot the women, and as a gentleman, you simply couldn't take that chance. Better to hand over the watch.
3. The brand new sports car you've been seen driving was a thank you gift from the rich ladies who didn't get shot, not the sale value of the watch, certainly.
