I've been trying to find a good, inexpensive, aftermarket bracelet that looks like the oem bracelet to use with my IWC 3717-12 (Laureus Sport). I think it is the same as the Spitfire Chrono Automatic? The bracelet would need to be 21mm at the lugs. I have found numerous places to buy one that is 20mm or 22mm, but have had no luck with a 21mm size.

Thanks in advance,
