Ralf Tech WRB Automatic California WRB 1007
The French brand Ralf Tech continues to expand its WRB collection with a limited edition called the WRB Automatic California. This model incorporates the main technical features of the range while adopting a California dial, an iconic configuration in military watchmaking. Produced in a limited run of only 100 pieces, this watch combines a design inspired by historical timepieces with a contemporary construction intended for everyday, nautical, and professional use. True to the brand's philosophy, it prioritizes functionality, robustness, and legibility, while remaining consistent with the watches developed by Ralf Tech for the most demanding environments. It is available for around €1,700.
A brand closely linked to maritime professionals
Founded in France in 2005, Ralf Tech specializes in professional diving watches. From its inception, the brand has focused its development on military divers, combat divers, intervention units, and professionals working in maritime environments. Unlike many brands that simply draw inspiration from the military, Ralf Tech develops its models in collaboration with field users to meet real-world requirements for robustness, legibility, and reliability. Over the years, several of the brand's watches have been worn or tested by members of special forces, marine commandos, bomb disposal units, intervention groups, as well as various French and international government agencies. This close relationship with operational users is one of the cornerstones of Ralf Tech's identity and explains the highly technical focus of its collections. The WRB range adopts this philosophy in a more compact format, while retaining the essential characteristics of a true tool watch.
A California dial directly inspired by military watchmaking
The main distinguishing feature of this edition is its California dial, instantly recognizable thanks to the combination of Roman numerals at the top and Arabic numerals at the bottom. This type of display appeared during the 1930s on several military and professional watches to improve instant time reading and reduce the risk of confusion in challenging conditions. Even today, the California dial remains associated with historical military watches and the first diving watches used by certain specialized units. Ralf Tech has adopted this visual signature, adapting it to a modern watch. The hour markers and hands are coated with Super-LumiNova Old Radium, offering excellent legibility day and night while evoking the color of vintage luminescent materials.
A diver's watch designed for everyday wear
The WRB Automatic California retains the compact 39mm case characteristic of this collection. Crafted from 316L stainless steel, it features a unidirectional rotating bezel, a screw-down crown, and a screw-down case back ensuring water resistance to 200 meters. The entire assembly is protected by a domed sapphire crystal with an anti-reflective coating. Beneath the dial lies the automatic caliber RTA003, a reliable mechanical movement providing hour, minute, and second functions with a power reserve of approximately 40 hours. Ralf Tech has opted for a proven solution, consistent with the watch's utilitarian purpose. This edition comes with two interchangeable straps: a Tropic rubber strap, suitable for water activities, and a hand-stitched calfskin leather strap, offering a more classic alternative for everyday wear.
A limited edition of 100 pieces
Produced in a limited run of 100 pieces, the WRB Automatic California completes the WRB collection with a variation that emphasizes historical heritage rather than technical evolution. Its California dial evokes the first military watches of the 20th century, while its design remains true to the current standards of dive watches developed by Ralf Tech. Offered at a retail price of €1,700, this limited edition is aimed at dive watch enthusiasts seeking a timepiece with a historical design, as well as those who have followed Ralf Tech's work with professional divers, special forces, and intervention units for several years.
In short, about the WRB Automatic California by Ralf Tech
With the WRB Automatic California, Ralf Tech isn't trying to reinvent its dive watch, but rather to offer a contemporary interpretation of an iconic display from military watchmaking. This limited edition retains the fundamentals that have contributed to the brand's reputation: a compact size, robust construction, excellent legibility, and a design conceived for demanding environments. Drawing on its experience gained working with professional divers, marine commandos, special forces, and various intervention units, Ralf Tech continues to develop tool watches where functionality takes precedence over style. The WRB Automatic California fully embodies this approach, combining a historical heritage with a modern dive watch intended for both demanding users and collectors who appreciate military-inspired models.
