DuographFlieger
Duograph-Chrono
Guinand baut Pilotenuhren seit Anbeginn der Fliegerei, immer dem gleichen Funktionsprinzip folgend – präzises Uhrwerk, widerstandsfähiges Gehäuse und Zifferblatt und Zeiger mit bester Ablesbarkeit.
DuographFlieger
Early pilot or deck watches often had numbers or indices thickly coated with green luminous color for optimal daytime and nighttime readability. For our model DuographFlieger we use green luminescent color of highest luminous intensity and combine this with an absolutely matt black dial. In combination with the bead blasted and therefore matt housing, the DuographFlieger is a classic navigation instrument for daily use on the wrist.

The Watch
The 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.
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 Movement
The Valjoux 7750 is regarded as the most matured and reliable chronograph caliber ever - developed in the 1970s and continuously improved, it is probably the most robust power source for a mechanical Pilot Chronograph. ETA, the manufacturer of watch movements, supplies Guinand with the movement for this watch in a decorated version with Perlage, Geneva stripes, blued screws and Glucydur balance.
At Guinand each of these movements is regulated once again in 5 positions before the final control of the watch ends with an accuracy test of several days.
The Housing
We manufacture the Duograph Series in a well-proportioned and at the same time robust, stainless steel housing. 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.
