The BOLDR Expedition Enigmath Schwarzland is a great watch suited for all of your mathematical adventures! 

With the Enigmath BOLDR goes back to the pre-digital age with this slide rule bezel math-wizard watch.  BOLDR has managed to capture a ton of practicality in this 41mm case, featuring a rotating internal bezel that can even be used as a slide rule to make calculations on the go.

A quick multiplication example of 9 x 12: align the unit index (red marker ‘10’, outer bezel) with ‘9’ on the inner scale. Locate ‘12’ on the outer scale and read the results directly opposite on the inner scale; ‘10.8’. Then, adjust decimals based on the expected value of 108.

All the goodness in this watch is being powered by the Japanese Miyota 9039 movement. Amazing lume? Got it. Of course the watch has sapphire glass (with an AR coating), 200m water resistance, sandblasted stainless steel case and a fine leather and canvas strap. Whether you're a math pro or not, it's simply a cool watch!

• We're an authorised dealer of all of our brands, unless otherwise noted. In this day and age there are also many 'grey market dealers' that compromise. What are the main benefits of buying from an authorised dealer with regard to the warranty?

  2 year warranty

  We offer a 2 year warranty on all watches. This covers all mechanical malfunction arising from parts failure and/or assembly errors. Excluded are parts that by their nature may not last 2 years, like batteries and leather straps, damage/problems caused by improper use and wear and tear. We stand behind the brands that we sell and the quality that they offer.
  Some of our brands also offer an international warranty, which will also apply.

  Service and parts

  In the unfortunate event of a problem with your watch, you simply need to send it to us (or take it to another dealer if the brand offers an international warranty). We have access to the official service centers, where only original parts are used and the watchmakers are qualified and experienced with your type of watch. Not every watch movement is the same, so it's best if it's handled by people who know what they are doing.
  After your 2 years warranty has expired we are able to offer service in most cases.
