Pocket watches need special care
The first reference to a pocket watch is found in a letter written by Italian clockmaker Bartholomew Manfredi in 1462. By 1510, pocket watches were being manufactured in Nuremberg, Germany by a master locksmith named Peter Henlein. The manufacture of these watches spread across Europe during the 16th century.
These watches are of two types. The lepine has a winding stem that is in line with the seconds-marking dial on the face of the watch. The savonette watch has a winding stem that is at right angles to the direction of the seconds dial, on the face of the watch.
A lepine’s winding stem is commonly found at the 12 ‘o’ clock position and points straight up. The winding stem of the savonette is usually found at the 3 ‘o’ clock position and points to the right.
A savonette watch usually has a “consular”, or “hunter” face, with a hinged lid over the face. A consular watch case has a lid on the back also, to allow the movement to be removed. A lepine watch has an open face with a scratch-resistant crystal.
Modern watches may not follow any of these traditional designs, especially those with a quartz movement. They often use a combination of the designs.
The mainspring is meant to be fully wound every day. You cannot over-wind it. Most watches that have been fully wound will run for 26 to 30 hours, though a few can run for 60 hours. A few can even run for as long as 8 days! Usually watches are wound clockwise, though there are exceptions. Some antique watches use a key to wind the mainspring and to set the time.
