Nivada Grenchen Autochron 38mm Orange Chronograph Black Dial Rubber Mens Automatic Watch 77004A27

The Nivada Grenchen Autochron Automatic Orange 77004A27 combines a 38mm 316L stainless steel case with a matte black dial framed by a gradient orange chapter ring. Applied Super-LumiNova indexes provide contrast against the dial, while the three sub-dials display the chronograph functions. A date window sits at 3 o’clock, with the double-domed sapphire crystal protecting the dial. The case measures 12.75mm thick without the crystal and 15.20mm including it, with a 44.30mm lug-to-lug measurement.

ETA Valjoux 7750 Automatic Movement

The Autochron Automatic Orange 77004A27 is powered by the ETA Valjoux 7750 automatic movement, operating at 28,800 vibrations per hour with a 48-hour power reserve. The movement provides hours, minutes, small seconds, chronograph functions with a 30-minute counter and 12-hour counter, plus a date display. A screw-down stainless steel caseback and 200-metre water resistance provide additional protection.

Aluminium Unidirectional Bezel

The Autochron features a black aluminium unidirectional bezel with a 120-click mechanism and white markings for elapsed-time measurement. Its black finish works with the orange chapter ring and keeps the focus on the chronograph dial. The bezel also adds a practical timing element to the watch while retaining the compact 38mm case proportions.

Orange Tropic Rubber Strap

The watch is fitted with an orange Tropic rubber strap that continues the colour scheme of the chapter ring and dial details. Its textured surface and perforated design give the strap a sporty appearance suited to the Autochron's chronograph layout. The 20x16mm strap is secured with a buckle, completing the orange-and-black configuration.
