Caliper Slide View MKII BST

$375.00 USD

Thanks for taking a look at the second version of the Caliper Slide View, a wristwatch with a legible and practical slide rule calculator.  
  • Made in Germany
  • Black Dial
  • Blue second hand and details
  • Steel Case (316L Steel)
  • Mineral crystal scratch resistant glass
  • Water resistant to five atmospheres
  • Swiss Ronda quartz movement with five-year battery life
  • 43 mm case diameter, 10.5mm height, 22mm band width
  • Super Luminova lume
  • Leather strap with blue stitching and quick release pins

 

The Slide rule index is at 12 – at the top of the dial. This is the conventional ‘starting point’ on a watch dial.

There are no conversion factors on the dial. This reduces clutter and lets you focus on the setting that you have selected.  We have a large number of conversion factors on the back of the case that you can easily refer to, and memorize over time!

Is this just a historic curiosity? Why would you want to use a slide rule? And why would you want one on your watch?

Here’s why: a slide rule is faster than a calculator when you need to multiply or divide many numbers by the same factor. This would be the case for units conversion or currency conversion. Set a slide rule to a particular factor, and you can read back and forth across the dial to get results for any value almost instantly. Doesn’t that sound like something useful to have on your wrist?
