Historical background
The strangely familiar yet unusual look of the California Dial originated in an era when clear orientation was vital for survival: pilots and sailors in the 1930s appreciated the combination of Roman and Arabic numerals because it remained easy to read in all lighting conditions and under stress. This design, which was later given the name “California” in Japan, still carries an aura of practicality and style today – lending the new WRB edition a historical claim that does not come across as mere nostalgia.

Origin and identity
The WRB was originally developed for divers in the French army and was first used for military purposes in 2019; since 2020, the model has also been available to civilian wearers, revealing its true identity: compact, robust, and unadorned. The current limited edition combines this tradition of use with meticulous craftsmanship and demonstrates how to seriously continue a proven concept without diluting the character of the watch.
Dial and readability
The matte, deep black dial of the California version uses a warm-toned luminous material so that the hands and indices stand out clearly at night; the Old Radium coating also conveys a subtle vintage aesthetic that makes the historical reference tangible. This makes the dial not only a reading surface, but also an atmospheric element that reinterprets the connection between form and function with every glance.
Case construction and wearing comfort
The satin-finished 316L stainless steel case measures 39 mm in diameter and, with its moderate height, fits comfortably on the wrist; The crown at 4 o’clock reduces contact and protects against accidental operation, which significantly improves the wearing experience. Together with the domed sapphire crystal with anti-reflective coating on the inside, the design offers a combination of solidity and everyday practicality that you can feel immediately when you put on the watch.
Functional details
The WRB retains its diving DNA: the unidirectional rotating bezel clicks into place in 120 steps and serves as a reliable instrument for measuring time underwater, while the screw-down crown and ISO-certified water resistance to 200 meters promise practical safety. The package is complemented by a screw-down, engraved, and numbered case back that documents the limited edition and identifies the watch as a collectible item.
Mechanics and reliability
Inside, the RTA003® automatic movement, based on the Seiko NH35 and with a power reserve of around 40 hours, is a technically pragmatic concept that prioritizes durability and ease of maintenance. This reliable heart fits in with the idea behind the WRB: a watch that performs just as confidently in everyday use as it does in demanding situations.
Straps and versatility
The accompanying hand-stitched vintage calfskin strap with beige stitching gives the WRB a warm, classic look, while the additional Tropic rubber strap instantly transforms the watch into a waterproof, sporty instrument; the quick strap change makes switching between everyday life and adventure incredibly easy. This strap combination underlines the watch’s dual role as an elegant companion and a genuine tool.
Conclusion
The WRB Automatic California achieves the rare combination of historic design and modern usability: it takes the iconic dial motif seriously, dresses it in contemporary materials, and complements it with thoughtful details without abandoning its role as a tool watch. Anyone looking for a compact, characterful watch with a genuine background and solid technical values will find this limited edition to be a well-rounded and harmonious offering.
