Analog purists tend to scoff at the very idea of any sort of digital technology invading their mechanical timepieces, but even the most diehard will find it hard to ignore what Frederique Constant has done with their new Hybrid Manufacture. On one side you have a traditional movement with a 42-hour power reserve, but when you activate the Connected functionality, you get features like activity tracking for fitness and sleep, but you also get a worldtimer and a watch analytics function that lets you view rate, mplitude, and beat error right from the Frederique Constant app. The digital component has seven days of battery life and both the digital and analog components can work independently from each other.

For those who can't totally leave the analog world.
