I'm curious to hear about what people do with budget ($100 or so) automatics. I've been tempted by a few of these watches, in particular a couple from Seiko's 5 Series, but I've never pulled the trigger because it seems to me that they're essentially disposable watches... it's cheaper to buy a new watch than have one serviced, right? I'm certainly no watch expert so I'm wondering if I'm missing something? If not, how much time can someone reasonably expect to get out of a budget automatic (let's say a Seiko 5) before it's time to replace it?
