I bought the Gehäusedeckelöffner to open a Hilfiger and a Casio clock with six opening grooves. Unfortunately, the T-Bar will not open far enough - is estimated close to 3.4 cm, while the distance at my watch is approximately 3.7 cm between eg the first and the third recess.. Two adjacent grooves I can not use because then the 3rd socket is no groove. FFor odd number of grooves, or more than 6 recesses of openers but should also work with larger watches.
Therefore, I can not open any of the two clocks - CAUTION eg for large watches!
