What time is it?

In search for a new watch, as if I really need a new watch. The time is all around us, with clocks, phones, tablets, computers, TV, in the bus, on store receipts, and I still wear a wristwatch.
Beyond the beauty and fashion element of a watch, I like the idea of using a modern version of a portable timepiece that was created more than 500 years ago. Yes, the first portable clocks appeared in the 15th century!
