The Caliper Slide View MKII Slide Rule Watch offers a way to calculate quickly on the go. If you thought the first version of this timepiece was cool, you’ll love what this one has to offer. The Caliper timepiece has a calculator on the side that’s both legible and practical. Incorporating the minimal design of the slide rule into this timepiece delivers impressive computing power. By adding and subtracting logarithms, the slide rule lets you multiply and divide many numbers by the same factor. Designed to focus on clarity and legibility, the Slide View MKII has a useful, minimal look. The slide rule index sits at 12, and you won’t have cluttered conversion factors on the dial. Finally, using Swiss Ronda quartz movement, the watch runs on a battery that lasts about five years. Once you put it on, you’ll never want to take it off.
