Opens most modern water resistant watch cases with notches.
Maximum bit width 32 mm. E.g. a Sandoz 40 mm (case width without crown) has a distance of 29 mm between the notches,
thus this opener will fit.
Even this tool is slightly more difficult to use for beginners due to the higher distance from the bits to the handle
(tilting risk when applying torque).
It is milled entirely out of brass.
Even if you are only "collecting" watch tools (rarely use them), this one is a very nice collectible watch tools in my eyes
