I'm servicing a French Clock with smallish Barreled Mainsprings. When I opened the Timeside Barrel I found it full of Dry Graphite. The dry graphite seems to have worked very well in this clock. I'm wondering if I should order graphite & return it to what seems to have worked well in the past, or use synthetic oil as I usually do? Most of my repairs have been on American Clocks, and this is the first I've encountered which was lubed with Graphite. My brain is sayin............If it aint broke don't fix it...........stay with graphite. But there are repairers on this board far more experienced than me. Pictured is the strikeside barrel prior to dis-assembly.
