Pilot Chronograph

Duograph

The Duograph-Chrono

The model 40.50.04 Duograph-Chrono is a chronograph with an especially clearly arranged dial in the tradition of our series 40 Pilotchronographs and the legendary Chronosport 351 model - 2 stop counters together with the central stop second do enable stop time measurements up to 12 hours. We designed this watch without the permanently running small second - in favor of the size of the two stoppcounters.

Duograph-Chrono

The model 40.50.04 Duograph-Chrono is a chronograph with an especially clearly arranged dial in the tradition of our series 40 Pilotchronographs and the legendary Chronosport 351 model - 2 stop counters together with the central stop second do enable stop time measurements up to 12 hours. We designed this watch without the permanently running small second - in favor of the size of the two stoppcounters.

The new model is optionally available with discreet matte black dial or distinctively white totalizers. Today, as in the past, it is known for its optimum readability, robust design and good wearability. In the cockpit and in everyday life. The light metal pilot bezel features bidirectional rotation and thus enables you to time short intervals without starting the chronograph. Protected pushers and a screwed crown with double O-ring seal enable reliable pressure resistance of 20 bar. Both the front and back feature scratch-proof sapphire crystal. The fact that the case design has barely changed in the past 50 years pretty much speaks for itself –– a true classic needs no improvement!

Duograph-Chrono RPanda

The model Duopgraph-Chrono RPanda is in the tradition of the 1960s sports chronographs with the distinctively color-coded totalizers from the rest of the dial. In contrast to the Panda optics (white dial with black totalizers) the readability of the time at the "Reverse Panda" dial of the Duograph Chrono RPanda is also optimal in low light conditions and darkness thanks to the black main dial and the indices coated with luminous color.
