Hanhart AMT5100 M

The AMT5100 M is a Swiss manual-wind column wheel flyback chronograph manufactured by Sellita's AMT division and used by Hanhart. It measures 30mm in diameter and 7mm thick, beats at 28,800 vph with a 58-hour power reserve, and features 23 jewels with Incabloc shock protection. The bi-compax layout pairs the column wheel mechanism with flyback functionality, allowing instant reset without stopping the timer. The movement remains in production and powers the Hanhart 417 ES 140th Anniversary models.
