One of the basic accessory facts that separate men and women is the fact that men wear very few accessories on a regular basis. A wedding band or class ring. A basic chain necklace with or without a cross or simple pendant. Maybe a single bracelet. If going out the bracelet and chain might match.
The one accessory we wear to make a statement is a wristwatch. Sometimes flashy if dressed up, sometimes monolithic and durable if worn daily for work. We wear different types of bands to match clothing or environment. So I guess it isn't surprising that one of the biggest categories of new Kickstarter projects is companies trying to reinvent something that was invented in the 1800s.
Divided by Zero started with two basic goals: to make a wristwatch that would comfortably fit anyone, and to base their designs on proven mathematical principles. They even went so far as to name each watch after the mathematician upon whose principles it's design was based.
Based on the geometry of Euclid, Plato, Kepler, and Gauss they have tried to ensure that every aspect from the size and shape of the hands to the placement of numerals and logo on the face reflect the mathematical principles of the timepieces namesake. As a stretch goal they added a Kickstarter limited edition version of the Kepler nicknamed the "Ancient Kepler" which features a weathered casing and khaki canvas band in an extremely limited edition of just 150.
So, does mathematical precision make a better wristwatch? I don't know if it is better than the rest (I'll leave that for you to decide), but I love the three they sent me (Plato, Kepler, and "Ancient Kepler"), and I will be wearing them all from time to time. You can get yours at their website.
