Case opener for screw backs "Precision"

Universal key for water-resistant watches. The width of the key can be adjusted and locked with a single knurled screw up to a diameter of 57 mm. The case opener can thus also be used on Big-Size watches, where normal case-openers do not open far enough. The transverse to the mounting jig enables precise and powerful opening or closing of the watches.
