- Before the arrival of the integrated circuit and the computer, the slide rule represented quite the pinnacle of technology. Allowing the user to perform complex calculations quickly and being able to use one was quite a skill; for working out anything from the service to pay at a restaurant to the amount of fuel and range remaining for an aircraft. Although Brietling were probably the most well known for producing slide rule equipped watches, the Calculator joined the Heuer range in 1972 and was powered by both the calibre 12 and 15 movements during its production run.
