Royal Oak Offshore Chronograph 42 TPD & Winder Settings | Swiss Watch Store
Wondering how to programme your watch winder for the Audemars Piguet Royal Oak Offshore Chronograph 42? You are in the right place. This model carries reference 26470ST. It is powered by the Cal. 3126/3840 movement. Below are the correct TPD and rotation-direction figures for this model, so your watch is always ready to wear.
TPD and Winding Direction
The correct setting for the Royal Oak Offshore Chronograph 42 is 600 turns per day, bidirectional: 600 turns per day with the rotor turning in both directions.
| Turns per day (TPD) | 600 |
| Rotation direction | Bidirectional |
| Movement | Cal. 3126/3840 |
Why the Correct Setting Matters
An automatic watch is only as accurate as its power reserve allows. Keep the mainspring properly tensioned and the Royal Oak Offshore Chronograph 42 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 Royal Oak Offshore Chronograph 42
The key feature to shop for is programmability: independent TPD and direction controls that cover 600 TPD bidirectional. Single-watch winders are ideal if the Royal Oak Offshore Chronograph 42 flies solo; multi-watch winders make sense the moment you own two or more automatics. Our watch winder collection covers both.
