Pin & Sleeve Bracelets
Not all watches have screw attached links, many still use pin and sleeve or just pin adjustment. These are simpler to adjust than screws, but come with their own issues. The main issue is damage to the pin. These are quite fiddly and if bent, will not go back in. Make sure also that you push them out in line with the arrow and put them back in reverse, i.e. against the arrow. Watch my informative video showing the steps to adjust a Tissot Gentleman bracelet.
