Based on the same technology that lets Citizen’s high-end watches with Eco-Drive stay perpetually charged by the sun, Q&Q (a company founded almost 40 years ago as part of Citizen) has finally made its once Japan-only SolarSmile watches available internationally. So for just $40 — with free shipping — you can get a simple timepiece that never needs winding, charging, or a new battery.
All that’s required of you is to set the time, and decide which of the fifteen different colours and patterns you want strapped to your wrist. Made from partly recycled materials, the watches are all waterproof to an impressive depth of 164 feet. And after a full charge they will keep running for about three and a half months without seeing the sun again.
