Iconic timepieces
In 1996, professional diver Frank Huyghe created the brand RALF TECH. TECH as in “technological”, relative to professional equipment, and in reference to what is called “technical” or “tek” diving, which is deeper than recreational diving and requires specific equipment.
RALF TECH is a family owned brand created by Frank Huyghe in 1996. Dedicated to manufacturing diving equipment for professionals (civil and military), the brand has been shifting towards watchmaking since 2003 with the WR project. In 2008, RALF TECH permanently focused on watchmaking and ceased its other activities.
