   The Tsuki-Yomi A.T. is a watch that I bought to prove that quartz is cool. It succeeds in every way in doing this. I am a sucker for accuracy, so to have a watch that automatically syncs up every night (which it does, every night without fail) is very important to me. The only important thing to note is that Citizen seem to be pretty bad when it comes to the colour accuracy of their advertising images. The red dial is only even slightly red when the light hits it in a very specific way. To me, the reality is better as one of my biggest concerns was that the bright red dial shown in the pictures could prove to be too distracting. While I am happy with the product itself, it's important to be aware of the difference between advertising and reality. The watch itself packs in as much information as possible, but never feels cluttered or hard to read. Beautifully designed, a masterpiece of engineering, and proves that quartz can be cool.

   • The shiny parts of the bracelet adds flair without being too distracting or flashy
   • The watch is light (thanks to its titanium case) and comfortable to wear
   • Guaranteed to be the most accurate clock in any room

   • The lume is slightly too weak to be useful
