The Citizen 0705 watch movement is similar to the 283 movement but features a flat hairspring instead of a Breguet hairspring. It shares the same functions as the 281 movement, such as a manual-wind chronograph with 60-second and 30/45-minute counters, a subsecond hand, and the option for a 12-hour display and calendar. The 383 movement utilizes a pillar wheel design for its chronograph function. This movement was introduced in 1932 and is distinguished from the 381 movement by its different pillar plate size.
