Heuer "Bundeswehr STERNZEIT REGULIERT", Case No. 3888, Ref. 1551 SGSZ, Cal. Val 230, 43 mm, circa 1968
A large military flyback chronograph of the German Air Force (Bundesluftwaffe), stock no. 6645-12-148-2298, in near mint condition - with leather portfolio stamped BUND 6675-12-308-6782, sky chart and astronomical yearbook for troop surveying in 2001
Case: steel, screwed back with military engraving: BUNDESWEHR 6645-12-148-2298, turnable bezel. Dial: black.
This watch is a measuring instrument rather than an aviator’s watch. The chronograph is regulated for sidereal-time and was part of the supplementary equipment "surveying theodolite"; it was used for the determination of time during azimuth evaluations (determined angle sizes). Sidereal-time comes from the fact that the Earth makes a full rotation in its axis every 23 hours, 56 minutes and 3,5 seconds. Sidereal-time is used when determining a location's exact co-ordinates on the Earth's surface. It was for this purpose that this watch was regulated to sidereal-time. As it also keeps normal time, "STERNZEIT REGULIERT" (sidereal-time regulated) was printed on the watch's dial face to prevent it from being mistaken with the standard chronograph.

The Bundeswehr’s Heuer flyback chronographs were made for the German armed forces from the 1960s to the early 1970s; Heuer produced the flyback chronographs according to the specifications of the different units of the troop, so that several variations of the model exist.
This watch is one of those models that only very rarely appear on the market - it is also in outstanding condition.
