Screw-down pushers
Screw-down pushers confer an additional mechanical aspect to our watches. In order to operate the stopwatch function, you have to first unscrew the collar and, then, close it again after stopping it. Chrono , screw-down pushers, caseback
Our display back case uses a blue anti-reflective sapphire crystal and thus allow for an unobstructed view of the pulsating calibre. One has the feeling that the soul of the mechanical automatic movement can both be felt and seen. The watch is alive. Together with the possibility of the custom labelled rotor, each watch becomes a truly personal gift – even to oneself. ETA 7750 Movement
After the takeover by ETA, the Valjoux 7750 was re-named the calibre ETA 7750. This is quite possibly the most successful automatic chronograph movement of all time. The calibre stands out due to its high degree of accuracy and robustness. It has 25 stones, a ball bearing mounted rotor and a uni-directional winding mechanism. The 7750 has a 1/8-second counter, a 30-minute counter, a 12-hour counter, 28,800 half oscillations per minute and has a power reserve of ca. 44 hours. The loss of accuracy is 1-6 seconds per day. Movement revisions are recommended every 3 to 8 years-TOP Execution

Stainless Steel
Not all steels are created equal. We use 316L stainless steel; one of the hardest premium steels in the world. In addition to its hardness and resistance, this high-quality steel stands out because of its finish as well as it very fine silver hue. 316L steel has a significantly lower nickel emission than, for instance, 904L steel, which is also a high-strength steel alloy. This is, for us, a reason to favour 316L stainless steel. 1

Modern
Every company has the mystique of its first employee, its first premises, its first product. The Chrono Modern is the founding mystique that has become a watch. It was the first "real" Maurice de Mauriac. What was revolutionary at the time was the dial designed by Daniel Dreifuss, which we now call the 0510 dial. The numbers from 0 to 55, rather than 1 to 12, indicated the time. The minutes are more important than the hours. An expression of the agility of its wearers. Since women also love this potent statement of time on their arms.

The team’s Lada Niva is the perfect symbol of the @dakarrally spirit. Not a polished promise of high technology, but an honest character. Angular, robust, reliable. A vehicle that doesn’t ask whether the road is comfortable, but whether it is possible. In the same way, the Lada moves through landscapes larger than any ego and through days longer than any comfort zone.

This watch rises from the sands of the Dakar. 🏜️🏁
Built on the Chrono Modern — the Oasis Rally Team watch carries our DNA within it: clear, honest, uncompromising. Its sand-coloured dial with fine texture feels as though the desert wind itself has shaped it. It captures the light of the Dakar and carries it forward — through the stages and into the everyday life of true rally enthusiasts. The tachymeter in the colours of blue flames evokes heat, energy, and passion.
The serrated bezel stands for resilience, reducing glare under extreme conditions; the heat-resistant textile strap is made for dust, heat, and constant movement. Sapphire crystal with double-sided anti-reflective coating, 100 metres of water resistance, and a robust stainless-steel case make this watch a companion that doesn’t ask questions — it simply goes with you.
Inside beats the ETA 7750. Visible through the sapphire case back, defying every movement. Here, mechanics become emotion. Time gains body and soul.
This watch is not a souvenir of the Dakar.
It is part of it.

Welcome to the toughest race on the planet: Dakar Rally 🏜️🏁 - and we are part of it @oasis_rally_team
It is not a race in the conventional sense. It is a trial that does not reward speed, but attitude. Precision. For us, this rally is a return to a feeling that runs deeper than motorsport. It is the sense of time as a companion, not an opponent. In the Dakar Classic, time is not chased — it is read. Stages are not won; they are passed. Every second matters because it tells whether human, machine, and moment were in harmony.
Sladi is back behind the wheel at the Dakar Classic. His Lada Niva has been refined with everything learned from the last Dakar, and there it stood — first vehicle on the grid, still in the dark, restless, tires clawing at the ground.
We are proud to be part of this years Dakar with the @oasis_rally_team 🏜️🏁
