FAQ
Is the Landeron 21 automatic or manual?
The Landeron 21 is a hand-wound mechanical movement: there is no self-winding rotor, so you turn the crown — usually once a day — to keep it running. It uses no battery.
What is the power reserve of the Landeron 21?
About 36 hours on a full wind — enough to run overnight off the wrist, though a day or two idle will let it stop until you wear or wind it again. Power reserve is how long the Landeron 21 keeps running once you stop wearing or winding it.
Does the Landeron 21 have a date function?
No — the Landeron 21 has no date complication, so every watch built on it runs a clean, date-free dial. That suits symmetrical and vintage-style designs, and means one less thing to reset whenever the movement is allowed to stop.
