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.

The Revival of a Legend

Gentlemen, step back in time with style with the new Chronosport from Nivada Grenchen. A jewel from the ‘70s revisited for the modern gentleman with only 20 copies of this watch were produced at the time making it a real treasure for collectors. A find, just the way we like it!

ORIGNAL CHRONOSPORT PROTOTYPE 1970’S

There is a lot of talk now about ‘prototype’ watches. We are, however, very happy to sell this as a genuine test piece by Nivada in as-new condition ( only a few tiny hairline scratches from storage !)– it has never been worn. We believe that these watches were made in only around 20 examples and were never commercially available. To us, the most interesting element of this watch is the singer dial that shares some of the details of the Rolex Daytona. The lume on the dial and hands has taken on a stunning, rich patina. Additionally the watch features a bi-directional rotating bezel, date feature and red depth rating. The steel bracelet is in outstanding condition. This watch is in completely untouched condition and we have decided to not even open this time capsule. The watch is running fine, but for everyday wear a service might be recommended.

With a Granulated Effect

The new Chronosport edition has retained its advanced technical characteristics while presenting a refreshed look. It now features a matte petroleum blue dial with a subtle texture and an innovative granulated effect that highlights the two embossed black sub-dials (minutes and seconds) positioned at 12 o’clock and 9 o’clock. A tachymeter scale encircles the dial, adding a touch of sophistication.The pointed baton indices, coated with white Super-Luminova and a cream dot, bring refinement to the design. The hands, also filled with cream-colored Super-Luminova, enhance the elegance.The thickly printed white logo and typography create remarkable visual depth.

Tachymeter Scale

How Does It Work?

Start: When the object or vehicle starts moving, start the chronograph. Stop: Stop the chronograph after the object or vehicle has traveled a known distance (1 km or 1 mile). Reading the Speed: Read the average speed directly on the tachymeter scale where the chronograph second hand has stopped. For example, if a car travels one kilometer in 30 seconds, the second hand will stop at the 120 mark on the tachymeter scale, indicating an average speed of 120 km/h.
