I'm sure you're found yourself in this position. You have an inexpensive watch that you like and use, but the battery has died. To replace the battery will cost you about $6. (that seems to be the going rate here in NYC) But for $10 you can buy a BRAND NEW WATCH! 

Thus, the dilemma -- Do you invest $6 in an old watch or pay a little more for a brand new one?

It's not a simple decision. I've had a dead Rolex knock-off on my kitchen table for over a month now. All it needs is a new battery, and it will be good as new... (well, good as a cheap Rolex copy can be). But I leave it on the table, thinking I will buy a replacement instead. But when I look at the cheap watches for $10, I think "Maybe I'll just replace the battery on the one back home." And months pass in this state of indecision.

I suppose one solution is to buy a quality watch, then the decision to replace the battery is a no-brainer. I'll think about it for six months or so and get back to you.
