Sinn 'On the Fly' Folding Extension H-Link

SINN 104W

Good stuff. It is a replica of the "easy link system" from Rolex and works perfectly on my Sinn 104 bracelet. Note that you should be familiar with bracelets and links replacements to set this Extension properly. I had to remove the diver extension to install this one but that's not a problem for me. For my size of wrist, I did place the easy link on the last micro adjustment, and you can notice a slight gap then between the clasp and the H link. Nothing to worry about. If you place it on the second micro adjustment, the gap simply disappears. Overall, very positive, I can now use my bracelets comfortably even if my wrist changes during the day.

Excellent fit and quality
