The link Defy Extreme is the rare watch I can imagine appealing to link both vintage heads and technophile hypebeasts, alike. It has the same sort of appeal that a fully kitted-out G-Shock does, and I mean that in the absolute best way possible. (Hat tip to my roommate for first identifying the similarities.) It's link the type of watch that makes you feel adventurous.

The second link approach, which has become increasingly common in the last decade, is to create a movement which has an openwork configuration from the very beginning. This doesn't have quite the mesmerizing high-wire-act fascination of the traditional approach, but what link you gain is much better control over the final design, as well as better reliability and, often, a broader canvas on link which to deploy decorative techniques.
