Ralf Tech WRB Full Lume

All about the Ralf Tech WRB Full Lume

RALF TECH, known as a specialist for emergency and diving watches, has established itself particularly with its professional collections WRX and WRV. The brand is now expanding its range with the new WRB Full Lume, which impresses with its compact size and eye-catching look.

design and housing

The WRB Full Lume comes with a diameter of just 39 mm, making it ideal for wrists of all sizes, even without a diving outfit. The housing is made of 316L stainless steel in a matt finish and has a classic, cushion-shaped shape. Thanks to a screw-down crown at the 4 o'clock position, which is deeply integrated into the case, there is no need for additional side protection. The watch is waterproof up to 20 bar (200 meters), which makes it perfect for diving and other adventures.

dial and luminosity

A special highlight is the dial, which is completely coated with C3 Superluminova®, which ensures excellent readability even in complete darkness. The hands are also made of 316L steel and feature bright Superluminova® C5 inlays, while the matt black indices provide a clear contrast. A robust, 2.5 mm thick sapphire crystal with an anti-reflective coating on both sides ensures optimal visibility underwater.

movement and functions

The heart of the WRB Full Lume is the proven automatic caliber RT003 (Seiko NH35). This mechanical movement offers a power reserve of up to 40 hours, which ensures reliable timekeeping even during longer periods of use. The rotating, unidirectional 120-click bezel ring conforms to the ISO 6425 standard and features a black anodized aluminum insert.

bracelets and equipment

For maximum comfort, the watch comes with two interchangeable straps: a robust black silicone strap and a classic Zulu strap in black. Both straps have a lug width of 22 mm and are secured with a 20 mm pin buckle. As a special extra, the WRB Full Lume comes in a waterproof polycarbonate explorer case, which is ideal for on the go.

Limited edition and availability

This exclusive watch is limited to only 50 numbered pieces, making it a sought-after collector's item. It is available in two versions: the classic stainless steel version for 1,600 euros and a PVD-coated Black Edition for 1,700 euros.
