Tools & Supplies Needed to Assemble a Watch

Beware of Cheap Tools made in India and China sold at certain websites. Cheap tools are cheap because they are cheaply made of poor quality materials. We do not supply cheap poor quality tools.

Your going to need a pair of Tweezers to hold the hands while setting the hands. A hand setting tool is needed, some people make their own by hallowing out a piece of pegwood or something else. Hand remover is certainly useful and so is dial protection while installing and removing hands. A movement holder is needed when installing stem, dial and hands. The stem in the movements needs to be removed, some watches have screw others a pin hole needs to be press in. The stem then need to be measured and cut to length needed. A file is need to file down flat any burs left over after cutting the stem. When installing the stem into the crown a pin vise is needed to hold the stem tight, so it can be screwed in tight into the crown. Before screwing the stem in some like to use just the smallest amount at the tip of loctite, crystal glue or crazy glue. Case opener/closer, dust bower, eye loupe and screwdrivers are all basic tools of the trade.
