Hanhart 115-MS

The Hanhart 115-MS is a manual-wind Swiss movement measuring 25.97mm in diameter. It features 17 jewels and an anchor escapement, with a stop seconds complication that halts the seconds hand when the crown is pulled out for precise time-setting. The movement includes a hacking mechanism and was primarily used in mid-century chronograph and field watches. A known issue with this caliber is the fragile setting lever screw, which can break if the crown is forced.
