Common Questions

What are the dimensions of the movement and do the hands fit standard clock shafts?
The movement measures 72x56x19mm with a shaft length of 17mm and thread height of 8mm. The hands include an hour hand (65mm), minute hand (100mm), and second hand (100mm). Ensure your clock shaft is compatible; maximum press forces are 25N for minute and 10N for second hand.
What materials are the hands made of and how should they be handled?
The hour and minute hands are made of aluminum (0.4mm thickness), and the second hand is copper+aluminum. Handle them carefully to avoid bending or damage.
What components are included with this product?
The product includes the HD1688 DCF silent scanning movement (model HR9410+903) and a set of metal hands: hour, minute, and second hands. A battery (AA) is not included. No clock case or dial is provided.
Is this movement suitable for a beginner DIY clock maker?
Yes, it is suitable for DIY clock makers, repair technicians, and hobbyists. However, it is not for those wanting a complete clock, needing better than ±1 sec/day accuracy, chime or pendulum features, or a ticking second hand.
How long does shipping take and is there any special checkout process?
This item ships from China. Delivery typically takes 7–30 days depending on the shipping tier. Checkout requires human approval for cross-border orders.
