Manual wind pocket watches and watches have been produced and distributed since the late 1700’s. Little has been added to the formula that makes up a fine timepiece since that era. Masters of watchmaking, such as Breguet, worked magic to produce their small machines that told time in the same manner it does today. Manual watches are mainspring driven pieces that use a series of gears, progressing to a balance (tick or heartbeat of the watch). No automatic wind unit is present. Manual wind watches typically are wound daily for use, hence Manual or wound by hand. Shop for mechanical watches
