For what it's worth, I visited Lemon after the Hodinkee article and was kind of disappointed in their selection of vintage pieces. Great for Leica cameras and vintage toy trains but for us watch nerds, pretty disappointing. Now Jack Road on the other hand, you have to go there for a large selection of new / used and vintage pieces (they have an english version of their website).

Also, check out this hodinkee article if you're looking for something ultra collectible:

Never been there myself but looked amazing. Good luck!
