A friend of mine is looking for such a gift to her (non-WIS) fiancee. I might suggest getting something on Ebay and getting it engraved. That might fit inside $100. Any other suggestions?
She sent me a link to pocket watches, with custom engraving, from Things Remembered. They fit in her budget, but from the descriptions I cannot learn much about the watches themselves. At least some appear to be mechanical (skeleton). Anyone know about the quality of these watches?
