NAUTILO line is a contemporary reinterpretation of the famous ANONIMO diving watches designed by the military engineer Dino Zei at the start of the 2000s. The new NAUTILO watches underwent numerous technical and aesthetic developments, maintaining a distinctive design, perfect dial readability and proven robustness. One of the most important features is the new ceramic bezel, with a dot and the numerals 20 and 40 engraved on it. The dial features the special brand's characteristic 'The triangle', represented with double baton indexs at 12 o'clock, 4 o’clock and 8 o’clock. This triangle is like a capital A, the brand logo. Another feature is an innovative structure protecting the crown at 4 o’clock and DLC (Diamond like carbon) finish, providing hardness, resistance and low friction . This watch comes with 2 different straps, the rubber one and the dual-color OTAN style strap.
