If you have small wrist, I would really suggest you to try on different size & even same style but different leather.
Years ago, DH picked up Extra wide clic clac (S) & Epsom KDT (S) for me while on his business trip. I never got to try before (far from boutique) & thought size S was the smallest size anyway. However, I found the the KDT size S is still big for me & it turns so often. As for the extra wide clic clac is quite heavy & got quite a bit of hardware scratches on the GHW. So, I didn't bother to check on any bracelets for some times.
A few weeks ago while on a Europe Trip visiting several H boutiques. I took the time to try on different eye catching bracelets inside the cabinet. There, I try on a XS KDT in croc & surprising it's quite tight! Then, another one in size S & it fits so well. So I compared the length with my Epsom KDT size S with the Croc KDT size S, my KDT is actually a few cm longer!
Anyway, I didn't pick the croc KDT because when I compared with the Barenia CDC (S), I just love the combo of leather itself, the width of CDC, the light weight & the adjustable CDC strap that fit my small wrist! It was totally love at first sight!
Surprising after a couple weeks of continuous wear, except starting to have the smiley showing on the hardware, there isn't any other scratches. A few days ago, the Barenia caught on a few droplets of rain, there was marks in the beginning, but it disappeared at the end of the day. I also wear the Barenia during hot & humid weather & due to the natural skin of Barenia, it's turning a little darker already. In fact, I am looking forward to that day. Lastly, I feel the CDC is getting a little tight after a long hot & humid day, not sure if my wrist swell or the sweat or the leather shrink. With CDC, I can easily adjust a little bigger. Another bonus reason loving the CDC now!
