I have managed to get another Heuer 1550 sg Bund. This one is in all its glory PERFECT. I have no other words. Doesn't have fighter jet pilot background like the last one I sold here, but this one is ALL original and in perfect working condition, and just been serviced, by my trusty watchmaker and a friend, never polished. Results from watch timing machine are, amplitude 292, beat error 0.1, and it is regulated to +3s per day. It comes with its genuine Heuer red leather box. And that is rare, really rare trust me :) It is manual wind Valjoux 230 Flyback chronograph, with column wheel, 44mm in diameter without crown. It is standard Heuer logo, no 3H-symbol only small T-Symbol, regular font version of the dial non cut, which tells that it is from late 60's early 70's. So I look for 2200 euro. I don't have Paypal here in Serbia, but I have sold three watches here already and have a good feedback's from forum members who bought them from me via bank transfer. In that price you will get genuine leather Hirsch Knight strap, watch will be shipped via Fedex or EMS and insured. Everything is in that price. I know it is not cheep but just look at it :) Thanks guys

Description from Konrad Knirim book
The first chronograph of Heuer-Leonidas for the Bundeswehr was Leonidas (cal. Valjoux 22) in relatively rare items and accordingly interesting for the collector. Next came Heuer and Sinn (cal. Heuer 1550 equal to Vx 23) in the same steel case like the Leonidas but with a somewhat different movement. The models of Heuer and Sinn are identical. The reason is that Sinn was the German supplier for Heuer of Switzerland. The chronograph of Heuer was supplied in a very interesting variation together with a theodolite for astro navigation, but regulated in sidereal time (cal. 1551 SGSZ). Vers.-Nr.: 6645-12-148-2298.
Movement: Valjoux MN 230, flyback function, 36 h 17 jewels, max. + 10 s/day, max. pressure: 3 bar, working temperature: -18 C to 6o C, Incabloc-shock resist, anti-magnetic, H3- luminescent, year of introduction: 1968, weight: 50 g, producer: Heuer-Leonidas S.A. Biel, Switzerland.
Application:
All hand-worn models had the fly back function similar to those of the Third Reich Air Force and to those of the French Air Force, which allowed the chronograph to be pushed back to zero while running, with the capability of immediate restart.
This chronograph is regulated to sidereal time and is part of an equipment for astronavigation ‘Vermessung Theodolith 6675-12-140-9136’ and to ‘astronomische Richtungsbestimmung,Vers.Nr. 6675-12-308-8782 ’ in a nice leather case.
The chronograph was used to get the time while observing the azimuth in astronomic measurements. A sun year has 365 days, a.sun day has 24 hours, because of the earth moving around the sun in one year a sidereal year has 366 days starting in spring and a sidereal day has 23 hours, 56 min.and 3,5 seconds. So for fast astronavigation a watch or clock regulated in sidereal time saves the calculating effort.
This watch has a separate reg.-no. and reference and is marked on the dial. The amount of pieces produced may be 50, so they are very rare
