content: This is a reprint of a book first issued in 1930. It does have some fascination, for instance in the comparison of gas vs. oil lighting for your workspace. For my purposes as a beginner looking for basic methods for mechanical watch cleaning and repair, it was practically useless.It gives equal time to fusee and Geneva watches and may well be of interest to an experienced person looking for a glimpse into the past, but not reccomended as a "practical handbook."
