Vintage Charm Meets Modern Design With its brushed/polished steel case, the Grand Prix offers a balanced, sophisticated aesthetic. Its domed dial – in Champagne, Silver, Black, Blue or Green with a semi-glossy sunray finish – is enhanced by polished hour markers, adding a touch of timeless refinement that catches the eye. With a diameter of 39mm and a thickness of 12.70mm, the watch is perfectly balanced. A vintage touch: the Grand Prix is equipped with a double-dome sapphire crystal with anti-reflective coating, ensuring optimal legibility. It is water-resistant to 5 ATM or 50 meters, underscoring its versatility, not just in formal settings. The choice of brown or black leather strap with topstitching adds a touch of subtle style. The watch is powered by a Landeron L24 Swiss automatic movement for exceptional precision with a 40-hour power reserve.
