But "31-day" movements are different from their 8-day cousins. They require more torque, more precise handling, and a slightly different set of habits. Whether you just bought one at an estate sale, received it as a gift, or have had it hanging silently on your wall for years, this guide will walk you through everything you need to know.

Tick tock. See you in 31 days.

Let’s get that pendulum swinging. Before we dive into the "how," let’s clarify what makes the Kassel 31-day clock unique. Unlike a standard 8-day clock (which is wound weekly), the 31-day movement uses a longer, stronger mainspring. This allows it to store enough energy to power the gear train for 720+ hours.

There is something deeply satisfying about a mechanical wall clock. In an age of smartwatches and phone notifications, winding a clock once a month feels almost like a meditative ritual. If you own a Kassel 31-Day Wall Clock , you have invested in a piece of engineering designed to run for an entire lunar month on a single wind.
