1858 Automatic Date 39 TPD & Winder Settings | Swiss Watch Store
The Montblanc 1858 Automatic Date 39 is an automatic watch: it winds itself from the motion of your wrist, but on the days it sits unworn a watch winder keeps the mainspring topped up. This model carries reference MB134351. It is powered by the Cal. MB 24.15 movement. Below you'll find the exact TPD setting and winding direction the 1858 Automatic Date 39 needs.
TPD and Winding Direction
The correct setting for the 1858 Automatic Date 39 is 800 turns per day, clockwise: 800 turns per day with the rotor turning clockwise.
| Turns per day (TPD) | 800 |
| Rotation direction | Clockwise |
| Movement | Cal. MB 24.15 |
Why the Correct Setting Matters
Too few turns and the 1858 Automatic Date 39 stops between wears; the right figure keeps the mainspring in its sweet spot, where the movement runs most consistently. And there is no risk in experimenting: a modern automatic cannot be overwound on a winder, because the mainspring's slipping bridle releases excess tension. Getting the setting right is about convenience and accuracy, never about avoiding damage.
