The principle most likely finds its origins in similar concepts, such as Leonardo da Vinci's "Simplicity is the ultimate sophistication", Mies Van Der Rohe's "Less is more", Occam's razor, , or Antoine de Saint Exupéry's "It seems that perfection is reached not when there is nothing left to add, but when there is nothing left to take away". Colin Chapman, the founder of Lotus Cars, urged his designers to "Simplify, and add lightness". Rube Goldberg's machines, intentionally overly-complex solutions to simple tasks or problems, are humorous examples of "non-KISS" solutions.
KISS is an acronym for "Keep it simple, stupid" as a design principle noted by the U.S. Navy in 1960.
The KISS principle states that most systems work best if they are kept simple rather than made complex; therefore simplicity should be a key goal in design and unnecessary complexity should be avoided. The phrase has been associated with aircraft engineer Kelly Johnson (1910–1990). The term "KISS principle" was in popular use by 1970. Variations on the phrase include "keep it stupid simple", "keep it short and simple", "keep it simple sir", "keep it super simple"…
Watch itself sometimes goes back to the basic: just to tell time…
Recently there are a lot of features that makes watch super complex to read the time and super difficult to use. Well, if a Watch is Simple enough, I believe that the focus on the watch would be on the dial, Rolex has produced once for all the simple watch with the super dial that is super difficult to make.
Those are no printed one. They are all either precious stone, gems and special rocks. Hmm.,.. go and see, if these are falling into the KISS principle!?
