I’m not amazed by this – Seiko has had this sort of thing since I was in diapers – but leave it to a Swiss company to make this a big fat deal. Essentially, it’s a digital watch with a microgenerator and a unqiue Ventura style that the kids seem to love.
The MGS version will look exactly like the Sigma watch except the Lithium battery would be replaced by a micro-generator powered by the movements of the user’s wrist and the case would use an even more hardened material called Titanox. The generator will be located on the top of the case and will be visible through a sapphire crystal glass for posterity purposes.
