The very first pocket watches up until the third quarter of the 19th century had
key-wind and key-set movements. A watch key was necessary to wind the watch and
to set the time. This was usually done by opening the case back and putting the
key over the winding-arbor (which was set over the watch's winding-wheel, to
wind the mainspring) or by putting the key onto the setting-arbor, which was
connected with the minute-wheel and turned the hands. Some watches of this
period had the setting-arbor at the front of the watch, so that removing the
crystal and bezel was necessary to set the time.
This watch includes a reproduction of the correct size key, it is not the
Verge Fusee Escapement
Used in antique spring-powered mechanical watches and clocks, a fusee is a
cone-shaped pulley with a helical groove around it, wound with a cord or chain
which is attached to the mainspring barrel. Fusees were used from the 15th
century to the early 20th century to improve timekeeping by equalizing the
uneven pull of the mainspring as it ran down. The mainspring is coiled around a
stationary axle (arbor), inside a cylindrical box, the barrel. The force of the
spring turns the barrel.
