The ref. 652.307 allsports : a HEUER trackstar stopwatch for referees

In the very late 60’s, HEUER adds to its catalog a set of economical stopwatches, built on pinlever movements. The popular plastic case trackmaster timers (ref. 8041, 8042 and 8047) are a commercial success (190 000 units sold in 1970) and HEUER decides to extends its “less expensive” offer. In the second part of the 70’s, the trackstar are released with other new ranges of pinlever movements timers (trackmate, supertrack…). While most of HEUER “economical” devices features a one jewel mecanism, trackstar ones are powered by a more accurate 7 jewels caliber (which is explictly mentionned on the dial, a quite unusual thing) .
Trackstar could be considered as an intermediary between economical and professional devices. By the way depending on the commerical documentation Trackstar is introduced as a category of its own or classified in economical section.

Trackstar stopwatches cover a large set of purpose from general to very specific like sky-diving or yacking. The ref. 652.307 is a pinlever version of the allsports ref. 502.907. Its dial is designed for referees, to time a set of 9 collective sport events, including the pretty confidentional “Australian football” !

The Tag-HEUER box

Like the 512.902 of this collection, this HEUER 652.307 is packaged in a Tag-HEUER box. As ever mentionned in the article on the 512.902, a manufacturing in the mid 80’s, while HEUER changes for Tag-HEUER is a probable explanation.
