Comments about the data

repeater: pendant operated, chain driven, 2 hammers on spiral gongs, hook-lever regulator
The example movement was applied in a watch which would today be called private label product; it is only signed with Paris on dial and movement, and thus the (Parisian) retailer needed just to add is name.

Example, year: signature; shock device
ca. 1780: N970, A Paris
