Researchers advise keeping your brain in shape by issuing it little challenges, e.g., "complete Sudoku before finishing coffee", or "regain motor skills by 9am". Test your brain with your watch, with STORM of London
Built from materials like scratch-resistant mineral glass and tenderly brushed high-grade steel, Storms utilize innovative displays that, while no likelier to make you be on time, at least make the process of telling time a little livelier. Both the ultra sleek Vibe (horizontal display/rubber strap) and futuristic MK 2 Circuit (vertical display/tri-band steel strap) utilize rows of LED dots you'll count to discern the hour; a button click switches the display so you can decipher the date -- if you do so before tomorrow, you're right. Seemingly familiar faces are equally diabolical: the square, all metal Montecristo has you look to hypnotically overlapping circle segments for minutes & seconds, while the seemingly helpful Remi obscures all numerals but those immediately useful -- then inverts the hour and minute display, outsmarting your years of conditioning, unless your dyslexia outsmarts first it
Some pieces don't require mental calisthenics, like the simple, skinny-banded Onis, and the MK V, whose analog hands're shielded by a shutter shaped like a shuriken -- time your puzzle-solving with it, and no matter how long it takes you to finish, you'll still be The Sudoku Ninja.
