Any of our TDs CAN source a bracelet only for you. Whether or not they WILL depends somewhat on you having an established relationship with them. It will help if you order a watch too. "I'll buy this watch and oh I need a bracelet too". Now you've given them incentive to not say no.
Some TDs have better contacts with certain factories. Some factories are less willing to sell parts than others. In a worst case scenario, buy the watch with the bracelet on it you want, then sell just the watch head or put it on a strap and sell it or on your oyster bracelet, etc. Be creative.
