NOTE: This product is specifically designed for National Self-Winding Clock Co. movements and is not intended for Self Winding Clock Co. Style A, B, C, or F movements. To power these movements, please see the Model 1900L, or the Model 1900GS or RS Kits.
The Model 1900WG-4.5V is specifically designed to drive the rare, collectible and very unique National Self Winding Clock Company (of Champaign, Illinois) movements. Most NSWCC movements have intermittent problems with contacts by design. The Model 1900WG-4.5V overcomes this issue with its built-in timing pulse which activates the coils every 6 minutes. This assures full run between winds and absolutely certain winding every time--without deteriorating the contacts. No modifications to the clock movement are needed; simply connect the Model 1900WG-4.5V to the clock's coils with the included vintage cloth-covered wires.
If you prefer the "conventional" approach of utilizing the NSWCC movement's internal contacts, simply connect the device as instructed, and it acts as a conventional "super battery" with increased current output capability provided by its special ultra-capacitor output.
Other versions of this product can be made available for special clocks such as Landis. Please inquire.
Normal run time on typical NSWCC clocks with the Model 1900WG-4.5V has been found to be nearly 2 years in most cases.

A special thanks to Ray Brown for his help in evaluating prototypes, determining the proper parameters needed to drive the NSWCC movements, the company history, and for the great picture included below.
Important Note: Please allow standard 1-2 week delivery ARO unless otherwise noted in product description. Many products are built to order; all are handcrafted to assure impeccable quality. Timing products (such as the Model 1900S and 1900W series) require pre-shipment calibration and verification which requires time to validate quality performance (2 weeks).
Unless otherwise noted at Checkout, a handling fee of $5.00 is included in each order (also covers packaging material) in the continental United States. Therefore the total shipping number shown in Checkout is the sum of the actual fee (from the carrier, usually USPS) plus this handling fee. Our standard carrier is USPS Priority in the USA and USPS International outside the USA.
We try to maintain a policy of "no minimum order dollar amount," but handling fees cannot be avoided.
Policy on return shipping: Customer assumes responsibility for shipping and handling costs, regardless of reason. Restated: Customer pays for return shipping and handling in all cases, including warranty returns.
Ken's Clock Clinic reserves the right to adjust shipping fees or carriers to accommodate order size. If an adjustment is necessary you will be notified prior to shipment. This especially applies to international orders, although we strive to provide and adhere to best estimate possible at time of order.

We make every attempt to provide information needed to choose the right product. We encourage you to contact us if in doubt. Restocking charge is 20% of product purchase price on most models. We do not pay return postage if you choose the wrong product. We no longer carry non-renewable batteries to avoid problems with returns.
If you change your mind and don't want the product, you will receive a store credit.

We have terms on our generous warranty to avoid our generosity being exploited. We do NOT warranty product that has been disassembled, tampered with, modified, or abused. Our products are not hobby or experiment platforms and are not meant to be used for this purpose. You will pay replacement price if you modify or disassemble the product, damage it, then attempt to return it for warranty repair.
We strive to learn from any defective product. If a unit is modified or disassembled, this destroys the root cause traceability and an opportunity to improve product is lost.
There are some products (for example, the Model 1900WG-4.5V) which are non-returnable due to their low sales volume or custom nature. These are noted in the product description. Please contact us to verify application before purchase.
