This is the first mechanical cellphone done by extraordinary watchmakers Richard Mille and the Confrerie Horloger. Amazing! Mind you, it is not just a concept, you can actually own it if you have spare $275,000. If you think it is little too much, this may convince you - the name of this masterpiece is Celsius X VI II Remontage Papillon. It must be worth it with such name!
