[Curved] King Hybrid Rubber - Black with Deployant Clasp

Does not operate as advertised . Would not recommend this strap.

Excellent watch strap, it’s my 2nd purchase. I pair it with my Tudor Black Bay to give it the rugged tool look, would highly recommend as this a quality watch strap

Good fit with small gap to case if you don't like the bracelet.

Fits a Black Bay 58 perfectly

Tried to fit to my SRPD55K. Got it to fit with the modified spring bars, but due to excess material at the curved end of the strap (where it meets the watch case) and the thicker part at the top 1" of the strap, it made the strap angle immediately down at about 90deg from the case. So when fitted to the wrist, the watch would sit "up" off my wrist. leaving a gap of about 10mm between my wrist and the bottom of the watch. I tried to remove some of the excess material, from the curved end of the strap, to allow the watch to fit "flatter" against my wrist but this is hard to do and keep the original curve correct. I did manage to get it "sort of ok". But then I found the clasp, when closed, sits on the under side of the strap. Makes it bulge and sit uncomfortably. I would also suggest the material it is made from is a little stiff, I was hoping it would be more flexible. More like my Samsung smart watch, would have been preferable. At this point I decided to give up. The strap itself is beautifully made, looks great and is excellent quality, and on the right watch would be a really nice addition. but for the Seiko SRPD5...its just not right.
