RALF TECH WRB Automatic “Slim” Purple Mood
 
The RALF TECH WRB Automatic “Slim” Purple Mood is a professional diving watch with a warmer, more unexpected personality.
Originally developed from a model designed for French Army divers, the WRB has become one of the most versatile watches in the RALF TECH collection. Compact, robust and genuinely capable, it offers the seriousness of a true tool watch in a size that feels natural for everyday wear.
With the new “Slim” generation, RALF TECH has refined the case profile to make the WRB even more comfortable on the wrist, without compromising the durability and 200-metre water resistance that define the brand.
The result is a watch that feels ready for the water, but equally at home far away from it.
 
Purple Mood
The Purple Mood dial is what gives this WRB its character.
Its sunburst and smoked purple finish creates a constantly changing play of light, shifting from deep and moody tones to brighter, warmer reflections depending on the angle and surroundings. It gives the watch a sense of movement even before the seconds hand begins to sweep.
This is not a colour chosen simply to be different.
It brings a new emotional dimension to the WRB: more contemporary, more expressive and more connected to the light of summer, while still preserving the technical identity of a serious RALF TECH diver.
The contrast between the purple dial, white Super-LumiNova markers and black bezel gives the watch excellent legibility, while the 39mm case keeps it balanced, practical and wearable.
 
A Slimmer Professional Diver
The WRB Automatic “Slim” has been redesigned to sit more comfortably on the wrist. Its reduced profile makes the watch easier to wear throughout the day, allowing it to move more naturally between sport, travel and everyday life. The off-centre screw-down crown at 4 o’clock also improves comfort by reducing pressure on the wrist.
This is where the WRB Purple Mood becomes especially appealing.
It has the technical credibility of a professional diving watch, but the elegance and wearability to become a genuine daily companion.
 
Mechanical Performance
Inside the WRB Automatic “Slim” Purple Mood is the RALF TECH RTA003 self-winding mechanical movement, offering a power reserve of up to 40 hours.
The watch is equipped with a unidirectional 120-click rotating bezel compliant with the ISO 6425 diving standard, allowing precise measurement of immersion time. The screw-down crown and engraved screw-down caseback help ensure water resistance of at least 200 metres / 660 feet.
This is not a watch styled like a diver.
It is a real RALF TECH tool watch, built to perform underwater and on land.

The Sincrono Perspective
At Sincrono Luxury, we have always admired RALF TECH because the watches are not decorative interpretations of tool watches.
They are tool watches.
The WRB Automatic “Slim” Purple Mood is fascinating because it keeps that professional credibility while introducing something more emotional. The purple dial changes the entire mood of the watch. It softens nothing technically, but it gives the WRB a warmer, more expressive identity.
That balance is what makes it special.
A professional diver does not usually feel this elegant.
A colourful summer watch does not usually feel this capable.
The Purple Mood sits between both worlds — technical enough to respect, refined enough to wear every day, and distinctive enough to remember.
That is why it belongs in the Sincrono collection.
