<s>[INST] I am in the market for a luxury gift for a groom.  I found a high-end boutonniere watch with an 18k white gold band, which is an underrated piece that I feel perfectly suits his style.  However, I don't know much about luxury watches and, subsequently haven't pulled the trigger on the purchase.  I don't want that buyer's remorse feeling.  Specifically, the watch is a pre-owned Jaeger-LeCoultre Master Moon and it is valued at $9100.  The retail price was significantly higher, around $20,000.  I know that luxury watches can hold their value pretty well but what other factors should I consider here to avoid buyer's remorse?[/INST]
