A true revival of a 70s prototype, the Chronosport Blue Petroleum is a vintage-inspired automatic chronograph with a modern twist. Its matte petroleum blue dial features a granulated texture, creating a striking visual effect alongside the embossed black sub-dials. The dial is enhanced with Super-Luminova-coated baton indices and hands, ensuring excellent readability.
Powered by the Valjoux 7750-ETA automatic movement, this timepiece delivers 42 hours of power reserve and features a tachymeter scale for speed measurement. The 38mm stainless steel case is topped with a domed sapphire crystal and features a bidirectional fluted rotating bezel with a yellow dot accent at 12 o’clock.
Water-resistant up to 200 meters (20 ATM), the Chronosport Blue Petroleum is available with Tropic rubber, leather, and steel straps, offering versatility for any occasion.
At the heart of this watch beats a Valjoux-7750-ETA automatic movement, offering a 42-hour power reserve and complete functions: central hours, minutes, seconds, and date. The 38mm stainless steel 316L case, with a thickness of 12.7mm (without the crystal), is protected by a domed sapphire crystal with an anti-reflective coating, ensuring both durability and clarity. The Chronosport features a stunning bidirectional fluted rotating bezel, without clicks, just like the original, made of aluminum and adorned with a yellow dot at 12 o’clock for a pop of color and elegance. It is equipped with a tachymeter scale to measure speed over a known distance, a practical and aesthetic function particularly appreciated by racing drivers. Finally, it is available with a variety of straps: Tropic rubber, leather, and steel.
