Stopwatch HEUER ref. P6071

Vintage HEUER stopwatch ref. P6071 --- close-up shot ---

A very singular stopwatch

The HEUER ref. P6071 is a quite rare and singular timer. The reference number itself is unique and does not follow 70’s and 80’s HEUER nomenclature. Probably designed for a very specific purpose, this model is not either classified in any most known classical HEUER catalogs and commercial documentations, making the dial understanding a nice challenge.

A dial designed for … ?

With two colored and segmented scalings in its large central register, the dial is really special and uncommun in HEUER production. The internal register gradution has two 15-minute green parts separated by a 10-minute one. The external graduation is a set of four blue 6-minute sections spaced by 1-minute or 10-minute white ones. Despite long time searching, no sport and other activities matching with these configurations have been specifically identified. However it can be supposed it is designed for referees to help them to time sport meetings divided in two 15-minute half-times with a 10-minute break, or four-6 minute quarter-times with two 1-minute and one 10-minute breaks. This durations could be compatible with some old basketball reglementations or applied in universities or colleges. If you have any idea on the subject you are welcome to send a message here :).

Inside the P6071

The P6071 is built on trackstar range model featuring a 7 jewels pinlever cal. 412 caliber. The configuration is similar to the ref. 652.307.
