Instructions for fitting and shortening a metal watch band

This video tutorial explains how to fit a metal bracelet to a Sinn watch, using the Sinn 104 model as an example. The process applies to both drilled and standard lugs. Included with every Sinn bracelet are Allen keys, Loctite, and a two-ended tool. The flat screwdriver end is used to attach the bracelet. It’s recommended to separate the links beforehand to make the process easier.

After unscrewing the bracelet using the Allen keys (twisting gently if Loctite causes resistance), ensure the Sinn logos on the watch and bracelet are aligned for correct orientation. Work from the back of the watch to avoid front scratches. Position the bracelet’s end links onto the lugs and use the tool to depress the spring bars into place. Repeat for both sides.

Once attached, adjust the bracelet length to fit your wrist by removing links with the Allen keys and applying Loctite when reattaching. Ensure the watch head and clasp are centred on the wrist. The clasp also includes a toolless micro-adjustment feature for on-the-go fit adjustments.
