Automatic or hand-wound – what is the difference?
Automatic and hand-wound watches are both mechanical: a mainspring stores energy, while the balance wheel and escapement regulate the rate. The only difference is how the spring is wound.
Hand-wound: the ritual at the crown
With a hand-wound watch you tension the mainspring by turning the crown – usually once a day, at the same time. Many enthusiasts love exactly this ritual. Without a rotor, hand-wound movements are often slightly thinner and offer an unobstructed view through a display caseback.
Automatic: energy from movement
An automatic watch additionally has a rotor – a semicircular oscillating weight that turns with every movement of your wrist and winds the mainspring via a gear train. Worn regularly, it keeps running on its own. Most automatic movements can also be wound via the crown.

Which suits you?
If you wear your watch daily and like it uncomplicated, an automatic is the natural choice. If you enjoy the ritual of winding or want a particularly slim, classic watch, a hand-wound model will make you happy. If you set an automatic aside often, a few turns of the crown before putting it on help.
