Great enhancement to my Black Bay 41mm

Great quality item, just make sure you have the tools mentioned in the description to ensure it is installed correctly. Once in place it works a treat and makes my Tudor Black Bay 41mm a comfortable option as a daily driver watch, as whenever on the fly extension is needed is now easily available.

Perfect for Tudor BB58

This is the best solution to provide on the fly adjustments to your Tudor BB58. Don't hesitate to add this to your Tudor bracelet. It is a perfect fit and works flawlessly.

Phenomenal

Genius. The BB58 is known to have fitment issues with lack of a half link and only 3 micro adjustments. This solved everything, and more. Not only that, but the quality of the link matches that of Tudor with extremely flush fitment. Absolute must have.

Works like a charm

A bit expensive but works as advertised. Initially a bit stiff but after some use becomes quite smooth to use. Not jangly or rattly either. Very useful in summer when wrist swells up. Would be great if a video tutorial for installation was posted on the website as it takes a while to figure out how to install.
