The movement in detail
The movement’s idea
It all starts with a spring: it stores the energy that drives the movement. In a manual watch, the crown winds it. An automatic adds a rotor that turns with wrist movements. No battery participates in this arrangement.
Take two Grand Seikos: the manual 9S64 and automatic 9S65. Both have about 72 hours of power reserve and run at 4 Hz; the 9S65 can also be wound with the crown. Once off the wrist, they can therefore run for roughly the same time. The word “automatic” itself promises no extra reserve.
For a single everyday watch, an automatic does make life easier. Wear it, and the rotor replenishes its energy. A quiet office day may nevertheless be insufficient for a full wind. If the watch stops, restart it according to the instructions for that model: there is no universal number of crown turns.
Practical meaning
Manual winding has its own appeal: a brief ritual that brings a tangible connection with the mechanism. You replenish the energy yourself, without relying on wrist activity. Daily winding is not always necessary; it depends on the reserve and the brand's recommendations.
In a collection of several watches, the automatic loses part of its advantage: its rotor cannot help on a shelf. A watch taken off will stop when its reserve runs out. Count how many days it usually waits between outings, and consider how easy you find resetting the time and calendar. That is more useful than arguing over which winding method is “correct”.
Turn the crown during a fitting: is it easy to grip, do the guards obstruct it, and is it easy to unscrew? This small detail becomes part of every winding session. If you feel unusual resistance, stop and consult the manual. Movements have different limits; “wind to the stop” is far from universal advice for manual watches.
