RALF TECH has stood for professional diving watches since it was founded in 2005. Special Forces and diving service providers rely on the indestructible diving tools from France. Tested up to a diving depth of 3,000m and equipped with a French manufacture caliber, Ralf Tech also sets new technical standards with The Beast.

Tested under real conditions at -3000 meters and under static conditions at -4000 meters, it is one of the three deepest series watches in the world.

For everyone who is looking for an absolutely special diving watch. TBM1101.

NEW & original packaging. Comes with 2 additional bands in a huge case. With tool for changing the strap.

LIMITED EDITION only 77 pieces worldwide.


RALF TECH has held the depth record (330m) on the arm of a scuba diver since 2005 with the WR1. With The Beast, however, the average depth of the oceans (3,682m) was taken as a target and the bar was set a little higher: in static tests with the submarine manufacturer Triton, depths of up to 4,000m were achieved.

The Project The Beast was initiated in 2019 - with countless tests in compressed air chambers and with civil and military diving robots, RALF TECH left nothing to chance: The Beast is unmistakably a RALF TECH: cushion-shaped and yet round. With a diameter of 47.7mm and a case height of only 17mm, the Tool-Watch surprises with good wearability for professional divers and watch fans.

RALF TECH The Beast Manufakture First Edition Black

The housing walls made of matt stainless steel have a thickness of 12mm in critical load zones in order to be able to “take” strong impacts. The unidirectional rotating bezel was developed with professional divers. Not only is it particularly easy to grip and can be operated precisely with 120 “clicks” for diving and decompression times, but it is also extremely resistant thanks to the matt Ceramfine ceramic inlay. With a thickness of 6mm, The Beast has one of the strongest sapphire crystals on a series-produced watch.

The Beast has a new encapsulation systemdeveloped by RALF TECH, in which the base is anchored extremely deeply in the housing. This ensures long service intervals and, above all, a certified pressure resistance of up to 3,000m.

The new dial is very open, has a large surface area and is extremely legible. The indices have been specially deepened to accommodate a particularly large amount of “Old Radium SuperLuminova”. The Beast celebrates another premiere with the new French caliber from the Pequignet manufacturer: It is the first automatic movement that is completely developed and manufactured in France. With bi-directional winding , 28,800 oscillations/hr, high efficiency and stop-seconds, the new caliber achieves a 77-hour power reserve.

The Beast is available in a limited edition of 77 copies each with a steel case (6,800 euros) or black PVD-coated steel (7,000 euros) in my shop.

My conclusion:

David Drilling

"RALF TECH proves with THE BEAST that, despite the international, monstrous-sounding name, you can build a thoroughly French diving watch. Once you let the beast off the leash, it is breathtaking in every respect. RALF TECH claims to have achieved certified water resistance of up to 3000 meters with its black diver - In cooperation with the submarine manufacturer, it was even tested up to 4,000m. THE BEAST is enthroned in the list of the 18 best diving watches of 2022 & 2023 at the top. The edition, limited to 77 pieces, is powered by the elegant in-house caliber RTM001, which is manufactured for RALF TECH by Pequignet. The French automatic caliber offers a power reserve of 77 hours! This sets the next record. No wonder ...."
