A friend of my father custom crafted a wooden clock from curly maple lumber many years ago, it may be a "one of a kind design". My father died 14 years ago, I've had the non-working clock stashed away since.While doing some clean-up, the clock resurfaced and I decided to research new battery operated clocks and had a fairly tough search to find the exact size needed...so when Bear Woods popped up with the exact size, I ordered it.It did spend longer than anticipated in the postal system(s), but once delivered I installed the new clock and it has not needed re-set since - perfect time keeping, it appears to be a quality product. Hopefully it will last years and years.Thank You Bear Woods
