Netatmo is slowly creating a reputation for itself of combining smart sensors with neat design, having recently teamed up with Philippe Starck to produce a sleek wireless thermostat. Now, it's joined forces with Louis Vuitton to produce a bracelet that'll keep you safe in the sun.

The June bracelet—designed by Louis Vuitton and Harry Winston collaborator Camille Toupet—wraps around your wrist and uses a gem-like sensor to measure sun exposure. While it doesn't have its own display, it syncs with an iOS app to tell you how much sun has beaten down on your skin, what SPF sunscreen you should be using, and if you need to be wearing sunglasses or a hat.

Niche, sure, but skin cancer is very real and present threat, and it's all too easy to lose track of the time you spend in the sun. Netatmo plans to start shipping the bracelet in the second half of 2014 at $100, and it will be available in platinum, gold or gunmetal. [Netatmo via Mashable via Engadget]
