Has anybody seen this:
"The ESEMBLO-GRAF series, originally produced in 1949, is a complete set of volumes detailing with clear and concise directions the disassembly, reassembly and servicing of many of what were (and to some extent still are) the most popular and complicated chronographs. Volume 24 "Chronograph Repairing: Functional Adjustments to the Chronograph Mechanism" was the perhaps the most important of the entire series."
It's sold HERE
Or...via subscription HERE.
Is it worth looking at?? Does anybody have it?
