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

Close-up of a mechanical watch movement on a black background

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.

Titanium Case

Thanks to titanium's excellent strength-to-weight ratio, titanium cases are extremely durable yet incredibly lightweight on the wrist.

  • Lug-to-Lug Distance 50 mm
  • Case Height 13.5 mm
  • Case Material Titanium
  • Case Color Black
  • Case Finish Brushed

Sapphire Crystal

Nearly impossible to scratch, the sapphire crystal lens is as hard and clear as a gemstone. There are only a few materials known to the world that can scratch it.

Sapphire Crystal

Scratch-resistant

Sapphire is the hardest crystal available. Given its hardness it is near impossible to scratch, however, it can be prone to shattering if subjected to a heavy impact. Its scratch resistance is very desirable and as such there is a higher cost to sapphire versus other crystals.

Superluminova® On Hands And Indices

Super-LumiNova® in-fill is a photoluminescent pigment that acts like a ‘light battery,’ charging under natural or artificial light to deliver a brilliant afterglow in the dark.

Screw-Down Crown

The screw-down crown reinforces the case, enhancing water resistance with a secure, durable seal.

Screw-Down Case Back

Unlike other case back designs, screw-down case backs are threaded into the watch case, helping to create a secure seal that can offer added resistance to moisture, dust, and pressure.
