I lost one of the watch pins on my Casio F-91w today. I don't have pins that match the remaining one and it might be a little tricky to find a replacement. Is there any easy way to find out what size replacement I would need? Or is it a case where just to cut bait and move on to another watch?:

A month late, but nevertheless for future reference . . .
Take it to a watchmaker, a real one in a real B&M jewelry store that does watch repair and jewelry fabrication in house, not battery and strap changes. They have buckets of various pins and springbars with which to repair watches and other jewelry. That said, unless there's strong sentimental value to your F-91w, you can buy a brand new one for $9.95 USD from Long Island Watch which rivals the cost of having a jeweler replace the pin (or springbar).
