Standing at a beefy 45mm in diameter with a 15.5mm thick case, there’s no forgetting the Heuer calculator is on your wrist. It’s big,  It essentially looks like a cushion case Autavia took a large dosage of steroids and bezel. The two-register subdial design and the orange hands are very recognizable for ’70s Heuers. You’ll mostly find black dial Calculators (with and without orange accents), but Heuer also produced a blue dial version such as the one we are featuring here. Over its decade-long run, the Calculator was powered by the calibers 15 and 11, and the Valjoux 7740 – all of which place the crown on the off side of the case to the pushers.
