Adjustable Opener Back Watch Case Holder Tool & Watchmaker Tool,Metal & Plastic

The Dofover Adjustable Opener Back Watch Case Holder Tool & Watchmaker Tool is a useful tool designed to help users hold watches firmly when opening the back cover to replace the battery. The tool is suitable for use with round, oval, and oblong watch cases. It features a grip that holds the watch securely, although some customers have reported it can slip, causing the watch to pop out. However, users have found it to be much safer than holding the watch in the hand while trying to use a knife to remove the back cover. The tool works well for larger watches, including Y 50MM Invicta watches, as customers have noted, though it may need to be put in a vice to hold it in place while turning to open. Customers have also reported success using it for pocket watch movements. However, it does not work well for smaller watches or even bigger thin watches when using a 3-point case removal tool used by professionals. The tool holds the watch with four posts that grip the watch at an indentation in the center of each post. There is no freedom to raise or lower the point on the posts where the watch is gripped, which means the watch must be thick enough so that the back raises from the gripping point to above the top of the posts. Otherwise, the indentations will cause the posts to overhang the watch case, blocking at least one of the dimples on the case where the 3-point removal tool is set. Secondly, the posts rising above the watch's back will block the turning of a 3-point case removal tool, which defeats the purpose of the tool. Overall, the Dofover Adjustable Opener Back Watch Case Holder Tool & Watchmaker Tool is an average piece of equipment that can be beneficial in a jewelry shop where larger watches with screw-off backs can be challenging to open. However, it may have limited use if you frequently work with smaller and thinner watches.
