Got one of these and was amazed by the quality of it. I have a similar Hermes straps for the Apple watch and it feels the same!
The stitching of the strap is top notch, and smell of leather is amazing! I like that the offering comes in a variety of sizes to cater to smaller cases. It should be a standard for all straps to come with quick release spring bars, such as the ones that Delugs produce. Great product!
This is my 3rd strap from delugs and the leather is certainly premium in feel and so far in performance. My only negative comment is that the two straps designed to keep the tail in place are very thin and sometimes fold on themselves when trying to secure the tail.
Great quality strap that fit the wrist really well. Would suggest those with smaller wrists going for the size S instead of the M if adding a deployment clasp.
