Mechanical Automatic Movement
Automatic watches have no battery. Instead, these "self winding" movements use the natural movement of your wrist as a power source.
Mechanical Automatic
Powered by You
A mechanical automatic movement winds itself using the natural motion of your wrist — a rotor inside spins as you move, storing energy in a mainspring. This spring slowly releases power through a precise series of gears and an escapement, driving the hands in a smooth, sweeping motion. It’s a self-sustaining engine, no battery required. When worn daily, it stays powered continuously — keeping perfect time without needing to be reset.

Acrylic lens are a specialised form of plastic akin to Plexiglass and were commonly used in early to mid-20th century watches. It is a softer material that can be more prone to scratches but conversely is very shatter-resistant. Given its softness any scratches though can be buffed out. Acrylic lens are synonymous with vintage-inspired timepieces and thus can be found on our Marlin and Q Timex collections.
