Ralf Tech

Every exceptional watch has its feat, and the one achieved by the WR1, the first Ralf Tech watch, is quite simply exceptional. Initially dedicated to the manufacture of professional scuba diving equipment since 1998, the Franco-Swiss brand beat the world depth record in 2005, with an immersion to -330 meters for almost 10 hours, where the diver had on his wrist... the famous WR1 watch. This was all it took for Ralf Tech to dedicate itself to watchmaking, offering watches with exceptional features since 2008. Constantly improved thanks to the advice of experts, from the elite units of the Commandos de la Marine Nationale to the skippers of the Vendée Globe, Ralf Tech watches are designed by enthusiasts of fine watchmaking above all else, independent since time immemorial, who put quality before quantity. An insider's secret that we at Jane de Boy are delighted to share with you. > More about Ralf Tech

Frequently asked questions about the brand Ralf Tech

  • Where does the brand Ralf Tech come from?

    Created in 1996 by Frank Huyghe, a French professional diver, Ralf Tech was originally a brand of diving equipment for civilian and military professionals. It was not until 2008 that the brand began designing watches, thus abandoning its other activities.

    The name of the brand refers to "technical" diving, where the depths are greater than those of recreational diving. In 2005, the brand equipped diver Pascal Bernabé with a watch that accompanied him to a depth of 330 metres. To date, no other watch has equalled such a record.

  • Where are the watches made? Ralf Tech

    The watches Ralf Tech are first designed in France, before being manufactured in France (Paris and Morteau) or in Switzerland (Losone and Le Locle), depending on the model. The leather straps are made in France, in the Doubs region.

  • How to set an automatic watch or chronograph Ralf Tech ?

    The automatic watches of the brand Ralf Tech are equipped with an RTA movement.

    • To adjust the date, unscrew the crown and pull it out to the first click. Turn the crown upwards to set the date.
    • To set the day, unscrew the crown and pull it out to the first click. Turn the crown downwards to set the day.
    • To set the time, pull out the crown to the 2nd notch (2nd click) and turn the hands clockwise until the desired time is reached.
    • Once the date and time have been set, push the crown in until you feel a slight resistance, then push it back in, turning it gently upwards until you reach the stop.
  • How to set a hybrid watch Ralf Tech ?

    The Hybrid watches of the brand Ralf Tech are equipped with an RTH002 movement.

    To set the date, unscrew the crown and pull it out to the first notch (1st click). Then turn the crown upwards to change the date.

    To set the time, pull the crown out to the 2nd notch and turn it clockwise until the desired time is reached.

    Once you have made your settings, push the crown back in until you feel resistance, then gently turn it upwards until you reach the stop.

    In case of jerky movements of two seconds, you have to recharge the Hybrid system. To do this, simply wear the watch on your wrist for a few hours. When worn daily, a hybrid watch Ralf Tech is calibrated after about a week. The power reserve of the watch therefore increases the longer it is worn.

  • How to maintain your watch Ralf Tech ?

    Regularly cleaning your watch Ralf Tech will help to preserve its appearance and ensure that it works properly. To do this, you can use a soft brush to gently scrub the watch with soap and water. Then rinse it with clean water before drying it with a soft cloth.

    Before cleaning, make sure that the crown of the watch is screwed down.

  • How to get a watch repaired Ralf Tech ?

    Ralf Rech watches are guaranteed for 2 years from the date of purchase. The brand recommends a water-resistance test every 2 years and a complete inspection of the watch every 5 to 6 years. To do so, please contact the Service Centre Ralf Tech or an authorised dealer.

    Each intervention by the authorised service centre comes with a one-year guarantee. The workshop warranty excludes damage caused by improper use or misuse, as well as repairs carried out by an unauthorised third party.

    The warranty does not cover bracelets, clasps or normal wear and tear of the watch.

  • Are Ralf Tech watches waterproof?

    The Ralf Tech watches are suitable for scuba diving and are therefore fully waterproof. Some models in the WRX collection are even waterproof to a depth of 1,000 metres!
