Master Ultra Thin Date TPD & Winder Settings | Swiss Watch Store
An automatic like the Jaeger-LeCoultre Master Ultra Thin Date only stays accurate while its mainspring holds charge. This model carries reference Q1688420. It is powered by the Cal. 899 movement. Set your winder to the figures below and the Master Ultra Thin Date stays wound, accurate and ready to pick up.
TPD and Winding Direction
The correct setting for the Master Ultra Thin Date is 800 turns per day, counterclockwise: 800 turns per day with the rotor turning counterclockwise (anti-clockwise).
| Turns per day (TPD) | 800 |
| Rotation direction | Counterclockwise |
| Movement | Cal. 899 |
Why the Correct Setting Matters
An automatic watch is only as accurate as its power reserve allows. Keep the mainspring properly tensioned and the Master Ultra Thin Date 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 Master Ultra Thin Date
The key feature to shop for is programmability: independent TPD and direction controls that cover 800 TPD counterclockwise. Single-watch winders are ideal if the Master Ultra Thin Date flies solo; multi-watch winders make sense the moment you own two or more automatics. Our watch winder collection covers both.
