hi, for those of u that have a j12, just wanted to ask if u wear it everyday? is it quite a durable watch, being scratch proof ceramic etc.? have had my tag for 8ys now, and my cartier is quite delicate so i keep it for formal events. I'd really like to upgrade my tag for either a j12 or cartier roadster? what do u guys think of these 2 watches. i'm a dentist, so would need something quite hardwearing and water resistant as an everyday watch. would appreciate any opinions? thanks
