HEUER Chronosplit Repair and Modules

HEUER Calibre 100 LCD-LED Chronosplit - Main Page

The beautiful & iconic Heuer Calibre 100 Chronosplit LCD-LED wristwatch was originally launched in 1975, for the period it represented a brilliant marvel of cutting edge technology.


The bold design was modern and fresh, even by today’s standards. The bezel was wonderfully accented by the bright six digit LED display. Heuer utilised a LED display in the lower chronograph as it was fast and responsive and could easily display "live" 1/10 second timing, whereas early generation LCD display technology was too slow and laggy.
