Ralph Tech, a French concept

Frank Huyghe, a professional diver, created the brand Ralf Tech in 1996. RALF TECH watches are imagined and designed in France. They are then developed and manufactured in Switzerland or in France.

Uncompromising "Toolwatch" spirit

One of the main characteristics of RALF TECH watches is that they indicate real depth values and not theoretical ones as most brands do. The "ISO 6425 Diving Watches" standard is thus not only respected, but exceeded thanks to exhaustive specifications and an exclusive control process.

About Ralf Tech

Conquering the Deep


As early as 2003, Franck Huyghe develops a watch made to withstand the pressure of great depths: the WR1 is designed to accompany the diver and explorer Pascal Bernabé in his world records, hence its name: World Record 1. It is in 2005 that the record is beaten, a WR1 on the wrist: Ralf Tech watches are now sold in stores specializing in diving. In 2008, the company turns exclusively to watchmaking for professionals and works in collaboration with them: from 2010, Ralf Tech begins to equip the units of the French special forces.

Ralf Tech: quality and know-how


RALF TECH automatic movements and automatic chronographs are original ETA or SEIKO movements or modified in-house. Due to the significant size of their watches, it was essential to modify the structure and mass of the rotors to compensate for the inertia generated by the weight of the cases. RALF TECH has equipped itself with powerful tools to optimize the creation and manufacture of "handmade" bracelets for all the models in their collections. This is what allows them today to produce high quality bracelets in the French Jura region that are in line with their cases.
