Frequently Asked Questions

Q: Is the Sunon SL28 quartz movement compatible with 2115-20Z clocks?

A: Yes. The Sunon SL28 and SL28-6 quartz movements are designed as a direct, cost-effective alternative to the 2115-20Z movement, sharing the same compact dimensions (Ø23.70 mm diameter, 4.15 mm height) and three-hand day/date calendar functionality, making it a straightforward drop-in replacement in most compatible clock cases.

Q: What tools do I need to install this clock movement?

A: Most standard clock movement replacements require basic clock repair tools such as a hand-removal tool, hand-setting pliers, and a small screwdriver. The process typically involves removing the clock hands, unscrewing the old movement, fitting the new SL28 module, and reattaching the hands. No specialist workshop equipment is usually needed.

Q: How accurate is this quartz movement?

A: This movement is rated at ±60 seconds per month, which is standard accuracy for quartz clock movements in this class. For most wall clocks and desk clocks, this means you may need to adjust the time by up to a minute each month, which is typical for everyday timekeeping applications.

Q: Does this movement include clock hands or a battery?

A: This listing is for the quartz movement module only — clock hands and battery are not included. Please check your existing clock hands for compatibility with the movement's shaft dimensions before ordering.
