This is a quartz watch testing unit that has line release function.
Line release when used makes quartz watch hands turn very fast. This shows the gear train is ok and clears any particles or gumming stopping a watch from running.
You can often find this alone is enough to fix many non running quartz watches, so I would say this a must have tool.
We sell a range of great value tools and parts for watch, clock and Jewellery craft. Please see in shop.
