Seiko Presage Zen Garden Automatic. Apparently it's inspired by a traditional Japanese garden - the green represents the foliage and the textured grey batons represent the stepping stones - which is the kind of nonsense that appeals to me. Some mechanical watches have an industrial looking dial, but personally, I prefer a beautiful face that you can then turn over and peer into the workings.
Being an automatic with a 40 hour reserve, there's a gauge to show how much incidental winding I've given it. Thus I call it the gesturemeter.
