This bi-compax chronograph layout works wonderfully with the design. J880.4, which is based on the Swiss ETA 2824-2 automatic movement, fitted with a chronograph module produced by Swiss Dubois-Depraz.
Under t he hood you will find the Junghans Cal. It's very clear, legible and relatively utilitarian.
The design dates back to 1955 when Junghans made a pilot watch for the German Bundeswehr. The Junghans Meister Pilot Chronoscope Black 027/3794.00 is an incredible pilot chronograph watch.
