Ball Trainmaster 120

Ball Trainmaster 120

This timepiece is a tribute to the sixties version of Ball's Trainmaster, once the official watch of the American Railway Association. Clean and retro, it uses the best of modern tech, including scratch-resistant sapphire crystal and an automatic movement – though by the looks of it, you'd never know. And that's the point. [$6,000; ballwatchusa.com]
