The movement selbt runs very quietly and reliably - * if * you've made it because, to put the pointer at 12 clock. It took me a good 10 attempts (pointer on it, insert the battery, 12 Wait clock, 12 clock wrong end position, battery out, hands again, and the whole thing all over again). Pointer and shaft (s) are very delicate; if you are not going extremely cautious damage to the pointer. Finally, I have a "12: 00 o 'clock position: 00" a "11: 59: 45-position" accepted. As a precision clockwork that is not possible, of course, actually, though note the moderate price; Moreover, an exact time in seconds of the clock used by me is extremely important. It is interesting rather the independent switching from summer to winter time, and vice versa. The clockwork (the wavelength) is sufficient for dials up to 6 mm thickness. Shaft diameter: approximately 8 mm. Negatives: There is no catch available to hang this clock on the wall, but it's pretty easy to make something here. There are two small holes, through which you thread a thin wire and thus can produce a hanger. Conclusion: A technically good drive, which some but requires the commissioning of skill and patience. Therefore - and because of the lack of wall mounted 2 star deduction.
