I puchased a customized leather strap for my Breitling Chronomat41, and I have to say, the quality and appearance easily exceeded my expectations, it's excellent in every way! It took a while for them to make it, but after getting it in my hands, I have to say that this was definitely worth the wait! Even their deployant clasp impressed me, it has to be one of the more impressive aftermarket clasps I've ever purchased, very high quality. I'm very happy with the purchase, and I'll definitely be a repeat customer with Delugs in the future.
