replace mechanism on battery clockEven though there were no instructions, It was very obvious on how to do it. I had 3 wall clocks that were quite expensive and installing thrse movements, I was able to keep all 3 and they work great!The product specs show the measurements for each of the eight sets of hands that come with this product. The ornate hands (the very bottom set in the picture) are shown to measure 57 mm for the minute hand and 45 mm for the hour hand, which is exactly what I need. Unfortunately, these hands measure 92 mm (minute hand) and 65 mm (hour hand). These are way too big for my clock. I checked some of the other sets. Some are at least close to the shown measurements, others are not. That is not helpful as most people need a very particular size. Very disappointing that this seller can't get something as simple as a measurement correct.I broke one try to make it shorter, I could not make it shorter, I had to remove the glass on the watch to make this fit, works fantastic now but the glass made it look betterReplaced a ticking clock mechanism with one of these silent mechanisms. Kept time fine for three months then the time got WAY off. Even with a brand new battery. No warranty other than Amazon’s 30 policy. Would not buy this item again.Great price, quick deliveryReplacement for Quartz clocksVALUE FOR MONEYThey do the job but the old saying you get what you pay forReplaced broken drive.Easy to fit & good choice of hands. i used the larger black ones but spread them gold. Looks fantasticExcellent value for money with a good selection of hands.Easy to fit.cheaper than buying a new clock.Schnell geliefert, nicht hörbares Uhrwerk.Leider sind die kurzen "Schnörkelzeiger" nicht wie angegeben 57mm und 45mm sondern 92mm und 65mm lang (siehe Foto) und somit für meine Uhr zu lang.Zusätzlich fehlt für das zweite Uhrwerk das zweite Befestigungsset (Mini-Zubehör: Scheibe und Mutter).
