“Some watches follow the terrain, others seem designed never to leave it, whatever the conditions.”

It immediately evokes open landscapes, mineral reliefs, and places where time is measured as much by effort as by movement. The Ralf Tech WRB Tundra belongs to that world, a watch designed to accompany without failing, wherever reference points shift and reliability becomes essential.

There are watches chosen for a specific moment, and others kept because they adapt to everything. The WRB Tundra belongs to the second category.It feels at home in varied environments, on a rocky path, beside a river, facing wind, under rain, or simply within the dense rhythm of an urban day. It does not change its nature according to the setting, it remains constant.The green dial evokes natural landscapes, forests, open ground, the palette of rawer and more authentic environments. It catches light differently depending on the surroundings, at times deep and restrained, at times more vibrant.In such conditions, time must remain immediately readable. The generously sized indexes and hands impose themselves naturally. One glance is enough.

The bezel, operated with a firm gesture, becomes a simple reference point. A starting mark, an interval, a duration. Nothing unnecessary, everything useful.It is a watch that follows movement without ever slowing it down.With the WRB collection, Ralf Tech affirms a direct vision of the contemporary tool watch. The Tundra is a more organic, almost instinctive variation, yet still entirely faithful to the same demands for robustness and legibility.All-terrain watches follow a simple logic, they must work everywhere. Humidity, impacts, temperature changes, immersion. They must never become a constraint.The WRB Tundra embraces these fundamentals through a modern approach, resistant materials, genuine water resistance, a reliable movement, and ergonomics designed for real use.

Produced in 2025, the WRB-1004 reference belongs to the continuity of the WRB range, as a version oriented toward nature and exploration.At the heart of the watch beats the RTA003 automatic movement, developed to accompany intensive daily use.It runs at 21,600 vibrations per hour, offering a stable and regular reading of time, with an approximately 40-hour power reserve after full winding.This movement favors robustness and consistency, in a spirit perfectly aligned with the identity of the watch.The 39 mm stainless steel case offers an ideal balance. Compact, legible, and perfectly proportioned, it adapts to all wrists without ever losing presence.The unidirectional rotating bezel allows precise timing of intervals. Its action is firm and reassuring, true to a watch designed for action.The green dial, signature of this Tundra version, stands out through its depth and readability. The indexes and hands are treated with high-performance luminous material, ensuring a clear reading in all conditions.The sapphire crystal protects the watch with durability, while the 200-meter water resistance confirms its ability to perform in aquatic environments.The strap, robust and comfortable, supports the watch in all settings, from everyday life to more demanding conditions.

This Ralf Tech WRB Tundra is a watch of continuity. It does not belong to a single use, it moves through situations with ease.It is made for those seeking a reliable, legible and resistant watch, capable of adapting without compromise.This example is offered as a full set, in near mint condition, carefully inspected in our workshop. A recent watch, produced in 2025, ready to be worn immediately.
