Overseas Chronograph TPD & Winder Settings | Swiss Watch Store
The Vacheron Constantin Overseas Chronograph 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 49150. It is powered by the Cal. 1137 movement. Below you'll find the exact TPD setting and winding direction the Overseas Chronograph needs.
TPD and Winding Direction
The correct setting for the Overseas Chronograph 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. 1137 |
Why the Correct Setting Matters
An automatic watch is only as accurate as its power reserve allows. Keep the mainspring properly tensioned and the Overseas Chronograph will hold its rate and be ready to wear the instant you pick it up — no resetting the time and date. Set the TPD too low and the watch can run down between wears. The movement will not be damaged (modern automatics have a slipping mainspring that prevents overwinding), but an under-wound watch is simply not doing its job. Correct settings are about accuracy and readiness, not safety.
Choosing a Watch Winder for the Overseas Chronograph
For the Overseas Chronograph, look for a programmable winder offering a 800 TPD clockwise programme. One watch? A single winder. Two or more automatics? A double or triple winder keeps the whole rotation ready. You'll find suitable models in our watch winder collection — check the programme list before you buy.
