Laco automatic watches: how they work and how accurate they are
Archive (2020): Laco watches are no longer in our range, and the 40% discount previously mentioned in this article has ended. The article remains as an explanation of how an automatic watch works.
Laco is a German watch brand known for pilot’s watches and automatic watches.
German precision
Laco is a German watch brand with a long history, making watches for German pilots as early as the Second World War. Many current models follow the designs of those pilot’s watches.
A watch’s accuracy depends on its specific movement and adjustment, however, rather than its origin. The permitted deviation of a mechanical watch is usually around ten seconds per day, while a quartz watch gains or loses only a few seconds per week. Exact figures are in the description of the watch’s movement, or calibre.
Automatic watches
An automatic watch is a mechanical watch without a battery. A rotor inside turns with your arm movements and winds the mainspring. If you wear it every day, it keeps running by itself. If you wear it rarely or move little, automatic winding may not be enough. Many automatic watches can also be wound manually using the crown, depending on the movement.
Seiko Kinetic also uses a rotor, but differently: an automatic watch’s rotor winds a mainspring, while in a Kinetic, the rotor’s movement generates electricity stored in a rechargeable battery. Conventional battery changes are unnecessary, but the rechargeable battery ages over the years.
