RALF TECH is a family owned brand created by professional diver Frank Huyghe in 1996. Before designing their first watches, RALF TECH was dedicated to manufacturing diving equipment for both civil and military professionals, including the French Navy - equipping their combat swimmers with RALF TECH  diving equipment which they found to be reliable enough to meet the challenging requirements of their missions. The brand's shift towards watchmaking began in 2003 with the WR project.

In 2005 RALF TECH specially designed a watch for the world record dive by Pascal Bernabé. This watch was aptly named WR1 (World Record 1). Off the coast of Corsica on July 5th, 2005 Pascal Bernabé set a new world record for the deepest scuba dive - three hundred and thirty meters. With the ascent back to the surface lasting more than nine hours, pause after pause, alone in complete darkness. To calculate decompression times, Pascal used two dive computers and a watch… a RALF TECH WR1. No other watch has ever been able to rival it since the record set by RALF TECH on July 5th, 2005.

A second watch followed, the WRK1, and 330 watches were made to commemorate the 330 meters reached during the world record dive in the previous year. In 2006, the watchmaking world discovered this “out of the ordinary” company which, at its first attempt, shattered the world record for scuba diving. No watch ever before had gone so deep in the world of diving.

The interest aroused by the success of the WR1 and WRK1, not only in the world of diving but also among watch collectors, was immediate. As nature ran its course, two passions were now linked, that of scuba diving and watchmaking. Frank Huyghe decided in 2008 that RALF TECH would cease its other diving equipment activities and would devote itself exclusively to watchmaking with the ambitious project of designing, developing, manufacturing and distributing timepieces with character, both accurate, reliable, and robust, tested by professionals.

In 2010, the French Navy's Commando Hubert operators tested a RALF TECH watch model, the new WRX, during one of their missions in treacherous outdoor terrain. They had helped to develop the RALF TECH WRX in response to specific operational difficulties.

In a mountainous environment, with ever changing weather conditions and particularly violent terrain, the watch proved its solidity, reliability, and its water-resistance (not only to water but also to sand and mud).

The extreme world in which the first RALF TECH WRX watch was born foreshadowed the extreme uses that one encounters in an outdoor terrain, on land or at sea.

Since then, the RALF TECH WRX has equipped most of the French Special Forces units as well as the elite units of the French National Police and the Police Brigade.

Switzerland, Great Britain and Italy – among many others, have also equipped a number of their Special Forces units with RALF TECH watches. Mostly with the WRX model but also the WRV and the new WRB watches. In addition, RALF TECH has a NATO approval number allowing their watches to be supplied to the military in countries that are members of NATO.
