This is a very rare collector watch. AI-CAT155-08te Key-wind/Key-set Movements
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 original. Cylinder escapement
The horizontal or cylinder escapement replaced the verge escapement was much thinner than the verge, allowing watches to be made thinner.
Clockmakers found it suffered from excessive wear, so it was not much used during the 18th century, except in a few high-end watches with the cylinders made from ruby.
The French solved this problem by making the cylinder and escape wheel of hardened steel and the escapement was used in large numbers in inexpensive French and Swiss pocketwatches and small clocks from the mid-19th to the 20th century.
Instead of pallets, the escapement uses a cutaway cylinder on the balance wheel shaft, which the escape teeth enter one by one.
Each wedge-shaped tooth impulses the balance wheel by pressure on the cylinder edge as it enters, is held inside the cylinder as it turns, and impulses the wheel again as it leaves out the other side.
The wheel usually had 15 teeth, and impulsed the balance over an angle of 20° to 40° in each direction.It is a frictional rest escapement, with the teeth in contact with the cylinder over the whole balance wheel cycle. Bridge Style Layout
The metal bar which bears the pivot of wheel and is supported at both ends. The bridge style watch has two or three fingers to hold the wheels in place and together are called a bridge. The term bridge (horologically) is one that is anchored at both ends.
