Notes

This watch has a high grade finish and an escapement, balance and balance spring intended for high precision adjustment. This is quite an unusual feature in a watch with chronograph and repeating mechanisms because these functions inherently affect the timekeeping of the watch adversely, and therefore such watches are not usually made as high-precision timekeepers.
C.L. Weidemann The firm registered its name in 1883 with a trade mark for horological products of its own make.
