The Timex Black Max is coming! a bold statement. Timex gave the name Black Max to multiple models of watch throughout the 1870’s and later as quartz models in the 1980s.
1970s
There were 4  variations of the Timex Black Max produced in the 1970s. US and EU models (featuring “Great Britain” on the dial) with and without a calendar (date window). The defining style of a Black Max watches was a black case surrounded by a white tachometer bezel. The 70s model being a plastic coating on top of a metal body.
1980s
Timex Black Max watches manufactured in the 1980s also had a black case however the composition had moved to an all plastic design.

Black Max Clones & Copies
Many attribute the design of the Black Max to be heavily inspired by the Porsche Design Chronograph 1 -1972 Limited Edition. It seems other manufacturers were also similarly inspired. However, i’m sure you’ll agree these are all closer to the Timex Black Max than the earlier Porsche.
