Need a good watch (strap) shop in Turin or Milan

My wife and are in Turin for the ATP tennis finals this week. She is here for tennis and I’m tagging along for part time tennis and part time car museum enthusiast. During the train ride from Rome her watch strap broke on her Breitling Colt, leaving me with watch strap purchasing duties as well. Anybody know of a good place to purchase a strap preferably in Turin near the Porto Nova train station? Will be in Milan in a weeks time. I will try the Breitling Boutique, but am not holding my breath.

Can't help with shops but hope you both enjoy the tennis!
