Series 40
Our Serie 40 is the classic among modern pilot chronographs. The design is based on Guinand predecessor models (Guinand-Ref. 361, from the 1970s/Sinn 102) and the classic design of the early Heuer pilot chronographs, updated to the requirements of the present day.
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. A protected pusher 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!
