SEIKTOS MOD

SEIKTOS MOD combines a square 38 mm case, NH35 automatic movement and sapphire crystal with light, blue, green, gold-toned or dark dials, plus a steel bracelet or leather strap by model. It is an independent MedoMods homage to Santos-style design, not a Cartier watch.

Compare SEIKTOS by dial and strap

Start with the dial effect: light, blue, green, gold-toned and dark options create different contrast against the square shape. Then compare the strap. Steel continues the case line, while black or brown leather softens it. The product images show each dial, finish and strap combination.

Shared base, model-specific details

The listed SEIKTOS models use a 38 mm case, an NH35 automatic movement and sapphire crystal. Details such as the exhibition back, clasp and dial layout apply to the selected variant only. See the NH35 guide for the movement's basic operation.

Shape in context

Choose SEIKTOS for a compact square silhouette. For a rounder, integrated-sport direction, compare NAUT MOD.

SEIKTOS uses 38 mm stainless-steel cases and a mechanical NH35 movement that runs without a battery. For an integrated-sport watch with automatic or chronograph options, compare OAK MOD. The Lady collection includes the 31 mm NH35-powered Women’s Two-Tone Gold and the quartz Carré Gold, offered in 27 or 31 mm.

The configurator offers base watches for a build with your choice of components.
