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.
