Sure, I have a mobile, but I feel a bit silly digging in my pocket when I just want to check the time. Plus, there aren't many non-tacky forms of jewelry for men. Finally, there's just something neat about a completely mechanical solution which is simultaneously old-tech (concept) and high-tech (execution).
Searching for "Seiko 5" on Amazon turns up a lot of options, and the core mechanism has been around since the 1960s. My absolute favorite automatics are the Seiko SKX007 and 009 dive watches, which seem to be unrivaled in value for money.
I'm very curious if this old-tech option appeals to the 20-somethings as much as it does to me, a guy who grew up when digital watches and (gasp) calculator watches were the coolest thing on the planet.
