GMT-Master II Batman TPD & Winder Settings | Swiss Watch Store
GMT-Master II Batman — Winder Setting Overview
A Rolex GMT-Master II Batman (reference 126710BLNR) deserves the right care between wears. That means a watch winder programmed to its exact turns-per-day requirement and winding direction. The GMT-Master II Batman runs on the Cal. 3285 calibre. Here's the correct configuration for the GMT-Master II Batman.
TPD and Winding Direction
The correct setting for the GMT-Master II Batman is 650 turns per day, bidirectional: 650 turns per day with the rotor turning in both directions.
Why the Correct Setting Matters
Why does the exact number matter? An automatic watch relies on its mainspring staying charged. The right TPD keeps the power reserve topped up so your GMT-Master II Batman is running and on time the moment you pick it up — no hand-winding, no resetting, no faff.
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 GMT-Master II Batman
Any programmable watch winder that offers 650 TPD with bidirectional rotation will suit the GMT-Master II Batman. If it's the only automatic in your collection, a single-watch winder is the neat choice; collectors with several pieces will get more from a double or quad winder. Browse our watch winder collection to find the right fit — just confirm the winder lets you set TPD and direction individually.
