I am researching the beginnings of the self-winding watches and am looking for early examples. I am looking also for any information (except published within the last few decades) about their inventor, Abraham-Louis Perrelet. He was spelled on occasion Abram-Louis, Perelet, Perlet, Breguet spelled him once Perrellet.
Among them a special place hold ones with center rotor (like on the enclosed photo).
So far, all known early center-weight watches without bumpers (all five of them!) are based on a fusee movement. However, a watchmaker with over forty years of experience told me that in 1973 he repaired a center-weight pocket watch without a fusee for a collector from NAWCC California Chapter 56. He recollects that the rotor wound the watch only in one direction, the other direction was idle, the watch had going barrel, the plates and the rotor were mercury gilded but not the wheels. I would love to find and to examine the watch.
Hope someone can help. Thank you.
