was "how to clean".. How did they

Women, hmm but don't kid youself, many men are capable of this task because in old days and still is repairing mechanical watches even still make them and produce replacement parts by hand. Those mechanical wind up and analog quartz watches still require cleaning and lubing. Been there and have shirt for clocks and watches on making precision parts and also for computers. With more practice and proper tools, I can on more diffcult parts of certain parts in timepieces. But I can't yet due to no funds available for those tools I can machine fine parts by hand. Smallest wind-up watch that you can buy is (out of it's casing) size of 4 dimes stacked by seiko or russian made (cardial). Cheers, Wizard PS: Asolute master clock-maker can produce very accurate time-pieces suitable for nav. Beauiful piece of work! :-)
