Notes
Note: Fine example of a watch fitted with a
frictional rest escapement of "chaff cutter" type,
drawn from that invented by Debaufre in 1704, with
two escape wheels and a single pallet on the
balance staff. In England, this type of escapement is
known as "Ormskirk verge" for it enjoyed in this
region a certain amount of success soon after 1800.
