Coming soon: Winder for NSWCC Clocks!

February 25, 2016 by Ken Reindel

This year, in celebration of our 10 year anniversary of supplying No. 6 renewable batteries, we are introducing a product meant for use with National Self Winding Clocks. It is most unusual because it provides the winding pulse timing AND 1900G-like performance needed to drive these very stubborn clocks.

The NSWCC clocks are unlike any other self winding clock inasmuch as they require about double the impulse power due to a combination of low coil resistance and high coil to armature gaps. Our 1900G-4.5VN will drive them, with no problem at all. However (and rather unfortunately), the NSWCC design has unreliable contacts. The 1900WG-4.5VN NSWCC will eliminate the need for the contact, and connects directly to the coil. Every 7.5 minutes, it outputs the proper pulse with enough impulse power to wind the clock fully. A special thanks to Ray Brown for his help in clarifying coil configurations for the variety of NSWCC clock movements out there, and for test running our product for us.
