This is a genuine Breitling rubber diving strap. I removed this strap from my abyss after about 2 weeks of wear whilst I waited for my deployment clasp to arrive. It is in worn condition, this must be mentioned, it is not brand new. However it is in good condition, only worn during the day to the office. So light surface scratching on the buckle where the wrist rests on the desk and light rubber marks on strap from placing on and off. If you wear a strap you will have the same wear within 24 hours. It will fit Breitlings with a 20-18 strap. I also have another Breitling strap listed which is brand new. I will start the bidding at 99 pence, good luck with your bidding.
