Hey Dirk57, yep, het is een:
Revue Thommen 17061.6537 Slide Rule Watch
This Revue Thommen, 17061.6537, equipped with a 7750 Valjoux movement is a slide rule watch. In every other way, its a chronograph.
Zijn er verschillende van en van verschillende bekende merken. Meestal uitgebracht als "Aviationwatch" , en altijd gezekerd tegen onderdruk, waren jaren geleden verplicht voor piloten op lijnvluchten.
Aan u de keuze voor een nieuw :?:

Ontwerper/fabrikant was Nederlander.

geen idee?????
iets uit de militaire entourage?
(zit roel hier soms achter????)

yep
yep
nope, roel was er nog niet toen dit ding gebouwd werd.
Ah Max, gezien je vraagteken dacht ik dat het een vraag was...
Maar je hebt het goed!
The Norden bombsight was a bombsight used by the United States Army Air Forces (USAAF) and the United States Navy during World War II, and the United States Air Force in the Korean and the Vietnam Wars to aid the crew of bomber aircraft in dropping bombs accurately. Its operation was a closely guarded secret of World War II; however, Herman Lang, a German spy working at the factory, leaked the design to the Abwehr in 1938.[1] The Carl Zeiss Lotfernrohr 7, or Lotfe 7, widely deployed by the Luftwaffe, was an advanced mechanical system quite similar to the original Norden bombsight.
The Norden sight was designed for use on United States Navy aircraft by Carl Norden, a Dutch engineer educated in Switzerland who emigrated to the U.S. in 1904 and worked on bombsights at the Sperry Corporation before starting his own company. The Norden was later adopted by the USAAF
Ook gebruikt boven Japan, hoewel veel nauwkeurigheid daar vlgs mij niet vereist was...
Beurt aan Max!

Yep, is om drift te berekenen met ingebouwde weergave voor de aangepaste richting en tevens een rekenliniaal, gemaakt omstreeks 1920!:
26/3 This beautifully engineered instrument allows the navigator to determine how many degrees the aircraft is pushed off course by the wind and as far as can be determined it also calculates the ground rate and the airspeed needed to compensate. Constructed from aluminum (or duralumin) this instrument is made in the form of a circular disc of which it's outer chapter is divided into the degrees of a compass. Around the edge is a moveable pointer which allows the navigator to set (and then lock) the intended direction of travel. Another lockable marker can be fixed in the direction of the wind. The wind speed can then be set. Once this process has been completed, the instrument by ingenious means, calculates the wind drift and ground rate. The very upper scale can then be adjusted so that the airspeed needed to compensate can be calculated. This scale also swivels so that it can be set to the new course. Fixed to the end of this scale is a notch which presumably locates into a separate instrument which possibly transfers the course direction on to a map. In the centre of the instrument is a separate smaller disc which rotates, acting as a slide rule type calculator. Engraved into the reverse is a m/sec - km/st (km/h) conversion scale.
This piece was made in Czechoslovakia for the German market. The reverse bears the the makers mark, a biplane with the name "V. Hodek - Praha VII" (V. Hodek - Prague VII) above it. All the writing and scales are in German. Diameter of instrument : 133mm.

ja... maar hatelijk om ermee te werken .... tegenwoordig geukkig computers/FMS/MCDU die het werk uit handen nemen
Ik ga er eens over nadenken.
