Barcelona!
Visit Passeig de Gracia!
A lot of gen watch shops
Near the Barrio Gotico you can find a small market....a lot of seller and some nice Tudor/Rolex used watch, vintages, etc...
I didn't remember on which days you can find this small market
I would suggest to visit the beach: Barceloneta
Great walk, nice buildings, sun and sea smell
Then, check the inside Port Vell: nice restaurant where to eat sea food. I suggest Paco Alcalde.
I liked it a lot! It's reasonably priced for the quality... about 25-30
