H4 Panis-Barthez


The "H4 Panis-Barthez Compétition" is a high-tech timekeeping instrument which delivers outstanding performance in all environments, both day and night. In this timepiece, a green fluid loaded with fluorescent nanoparticles moves inside a jet black case, framed with a notched bezel in satin-finished titanium.

HYT and Panis-Barthez Compétition have designed the centre of the watch to express all the power of the endurance racing world, by picking up the colours of the steering wheels on their cars. The seconds indicator and the power reserve are therefore adorned with blue, red and green. The minute track is topped with a sapphire bridge, over which passes a red hand, guaranteeing the high level of legibility demanded of sports watches. Each bridge on the H4 is cut out to reduce its weight, just like a race car.
