Our know-how

ethics
RALF TECH watches are designed and manufactured in France. They are developed in Switzerland and tested worldwide before going into final production. They are then manufactured either in France or in Switzerland… and are then distributed and worn all over the world. That’s how it goes! Here’s why….
Our RTA002 automatic movements and RTAC001 automatic chronographs are 100% Swiss. Our RTH002 Hybrid movements use a modified Japanese design platform in our workshops. The same goes for our automatic RTA003 and RTAC002 chronograph movements. For us, “Swiss Made” or “Made in France” is therefore not just a simple inscription on a dial but a tangible and inherent aspect of meeting the official standards that are the foundation of the watchmaking industry.
Beyond these standards, we are particularly committed to our values as citizens of the world. In this respect, we are very mindful of the situation with our planet and our oceans. We therefore pay particular attention to the quality and origin of the materials we use in manufacturing our watches.
All our leather bracelets are made from farm-raised animals that respect CITES regulations. They are cut, assembled, and sewn by hand while respecting the artisanal traditions of French saddlers in the city of Franois in the Doubs region of France.
RALF TECH watches are the result of two cultures – French and Swiss – and a global environmental awareness. This synergy makes our watches exceptional in both their design and production.

water resistance
One particular feature in RALF TECH watches is to indicate real depth readings and not theoretical measurements like most brands do. The “ISO 6425 Diving Watch” standard is not only respected, but now goes above and beyond thanks to comprehensive technical specifications and an exclusive testing process.
Our test tanks are able to simulate dives with the capability of altering their conditions: immersion time, water temperature, salinity, magnetism of the surroundings, etc… in order to get as close as possible to a real life diving situation, whether civil or military. All these “markers” allow us to work on our projects in complete serenity.
All these tests are of course supported by the feedback from our divers and various special forces units operators who use our watches on a daily basis.
In addition, it seems important for us to say a few words about the helium valves seen here and there on some diver’s watches. With less than 50 divers in France and less than 250 in the world, so-called “commercial” divers, i.e. those who work under oil platforms or repair cables and various connections that run through the ocean floor, may, under certain conditions, require a watch equipped with a helium valve. Our professional clients, combat swimmers, Navy divers, offshore divers, have no need for it. As for recreational divers, a helium valve is unnecessary and we think it could render the watch more fragile. That is why we do not equip our watches with helium valves.

RALF TECH has equipped itself with high-performance tools to optimize how it creates and manufactures “handmade” watch bracelets for every model in the collection.
This has allowed us to produce handcrafted watch bracelets in the French region of the Jura with a high standard of quality that matches our cases, aesthetics, durability, and wearing comfort.
Beyond the effort put into selecting the most suitable leathers and treating them according to tradition, RALF TECH is committed to respecting environmental standards. All our leather bracelets are made from farm-raised animals that comply with CITES regulations.
All our leather bracelets are cut, assembled, and hand-stitched with the utmost respect to traditions used by French saddlers in the city of Franois in the French region of the Doubs.
