PanoMaticLunar 40 TPD & Winder Settings | Swiss Watch Store
Left unworn, the Glashütte Original PanoMaticLunar 40 will run down within a couple of days — a correctly set watch winder stops that happening. This model carries reference 1-90-02. It is powered by the Cal. 90-02 movement. Here is the TPD and direction this model calls for.
TPD and Winding Direction
The correct setting for the PanoMaticLunar 40 is 650 turns per day, bidirectional: 650 turns per day with the rotor turning in both directions.
| Turns per day (TPD) | 650 |
| Rotation direction | Bidirectional |
| Movement | Cal. 90-02 |
Why the Correct Setting Matters
The correct TPD mirrors what your wrist would do naturally across a normal day. It holds the mainspring at a healthy charge so the PanoMaticLunar 40 runs at its best and is ready to wear at a moment's notice — exactly what a watch winder is for.
Don't worry if you're unsure — you can't break a modern automatic with the wrong winder setting; the slipping bridle on the mainspring makes overwinding impossible. The right setting just keeps everything running at its best.
Choosing a Watch Winder for the PanoMaticLunar 40
For the PanoMaticLunar 40, look for a programmable winder offering a 650 TPD bidirectional 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.
