Heuer Calculator Watch Review

The watch offered here is named the Calculator, and was produced in 1972. This line of watches targeted professional users. They were big – and wear big, at 45mm in diameter and 15.5mm thick (that as huge at that time). This chronograph has a two-register subdial layout and is powered by an automatic calibre. The design is purely 70’s. You’ll mostly find black dial Calculators with and without orange accents (The later in our case), but Heuer also produced a blue dial version. Despite its size, and the characteristic layout of the crown and pushers (the crown on the off side of the case to the pushers) due to the automatic Calibre 12, the most important element of the watch was the incorporation of a slide rule on its bezel http://www.d4l.co/tag-heuer-replica.html.
The slide rule was analogue computing at its finest and was a product of an era where people did not have smartphones, loaded with applications. It was used primarily for multiplication and division, and also for functions such logarithms and trigonometry. Slide rules existed in a diverse range of styles and generally appeared in a linear or circular form (as in our case) with a standardized set of markings (scales) essential to performing mathematical computations. Slide rules manufactured for specialized fields such as aviation or finance typically featured additional scales, which helped in calculations.

The calculator is hugely impressive, offering enough “vintage” appeal, but at the same time having a contemporary size, sitting at 45mm. Also, it is an excellent conversation starter and why not a cool analogue gadget to impress your friends, while it comes from a company with a great pedigree in the creation of chronographs and tool watches in general.
