Ralf Tech
WRB Original Automatic - Full-Set

“A professional watch is not noticed. It accompanies you, staying in its place whatever situation you are faced with.”

The RALF TECH WRB Original WRB-1006 is a limited series of 100 pieces launched in 2025. With its 39 mm steel case, black dial with highly luminous green indexes, its RTA 003 automatic movement and its crown positioned at 5 o’clock, it embodies a compact professional watch designed for real use, both underwater and in everyday life. This example is offered full set, in near-new condition.

There is in this WRB a form of immediate obviousness. A watch that does not try to convince, but to accompany. The black dial, clean, legible, structured by indexes filled with green SuperLuminova, imposes an instinctive reading, even in the dark. Nothing is superfluous. Everything is designed to serve. On the wrist, the WRB surprises with its balance. Its 39 mm make it immediately wearable, almost discreet, yet without ever losing its professional dimension. It slips under a sleeve, disappears in movement, then comes back into view at the precise moment it is needed. In the morning, it accompanies a training session, running, swimming, physical work. At midday, it integrates effortlessly into a more urban setting. In the evening, it remains present, legible, reliable. It is a watch that never requires adaptation. It follows. Always.

The WRB line marks an evolution in the RALF TECH philosophy. Where the WRX expresses raw power, the WRB proposes a more compact, more mobile, more everyday approach. Introduced in the 2020s, the WRB positions itself as a direct response to the needs of active users looking for a professional watch that remains wearable in all conditions. It retains the brand’s core values, robustness, legibility, water resistance, while reducing its size to gain versatility. The reference WRB-1006, produced in 2025 as a limited series of 100 pieces, fully embodies this logic: a watch of use, rare, coherent, built to last.

At the heart of this WRB beats the RTA 003 calibre, an automatic movement developed for RALF TECH. It operates at 21,600 vibrations per hour, with a deliberately lower frequency than modern standards, in order to favor robustness and stability in demanding conditions. It is equipped with 25 jewels, contributing to reduced friction and long-term durability. Its power reserve is approximately 40 hours after full winding, perfectly suited to an active daily use. This movement does not seek decorative sophistication. It prioritizes reliability, readability, and the ability to function without failure. A mechanism designed as a tool.

One of the most distinctive features of this WRB is its crown positioned at 5 o’clock. This choice is not aesthetic. It is deeply functional. In diving conditions, this position reduces pressure points on the back of the hand and wrist, especially when the wrist is flexed or when wearing gloves. It minimizes the risk of discomfort or injury over time. It also limits accidental manipulation, as the crown is less exposed to direct impacts. In everyday use, this advantage becomes immediately noticeable: the watch never interferes, even during movement or activity. It physically disappears, while remaining fully operational. The steel case ensures proven robustness. The black dial combined with green luminous indexes guarantees optimal readability both day and night. The black rubber strap reinforces this utilitarian purpose. Resistant, flexible, perfectly suited for water and perspiration, it extends the all-terrain logic of the watch. Each element is designed to endure, to absorb, to accompany without fragility.

What truly distinguishes this WRB is its ability to move beyond its original environment. it is designed for demanding conditions, yet it fully expresses itself in daily life. For a sports-oriented wearer, it becomes a natural extension. It fears neither water, nor shocks, nor changing conditions. It accompanies effort, but also rest. It requires no special attention. It functions. Simply. It is a watch one chooses for what it is, and keeps for what it becomes. 2025 example, offered as a full set with original box and papers.
