Diplomatico 191 Posted May 3, 2021 So your aluminium insert is flat and you're tempted to sand it down in order to fit the bezel. NO! There's an official tool for this but an Rolex watchsmith told me a DIY method: Use the long neck of wine bottle and use your thumbs to evenly apply force on the outer edge. Do in small increments and the taper will come back which will reduce the diameter and make it pressure fit properly again. It's genius to be fair and best of all, it works. 2 Share this post Link to post Share on other sites
