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 Crystal

A lightweight plastic polymer with excellent impact resistance and a warm vintage appearance that can be easily polished to remove scuffs.

Acrylic Crystal

Highly impact-resistant

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.
