Replacement 1-day cuckoo clock chain, 0.90mm wire diameter, 61 links per foot (LPF — the trade measure of chain pitch) — the standard spec for German Black Forest cuckoo clocks fitted with Regula 1-day movements.
This chain fits Regula 25 1-day (30-hour) movements, and is also sold as the correct chain for the related Regula 35 and 70 movements.
- Regula 25 (1-day / 30-hour)
- Regula 35 (1-day)
- Regula 70 (1-day)
Confirm the movement backplate is stamped Regula 25, 35 or 70 before ordering, or count the links in a 12-inch section of your old chain — 61 per foot confirms this Regula spec, not the near-identical but incompatible 59 LPF chain used on Hubert Herr 1-day movements.
Fitting notes
- Supplied as a loose 180cm length, not pre-joined into a loop — cut to size once fitted over the chain wheel.
