Only quartz versions, and cheap not ultimate reps.
I have been there a couple of times, always nice to come back, beautiful and chaotic city
Rep Cloths and suits not bad at st/ Takkeciler numbers 48-50.
You can find just one store close to the central market "Gran Bazar" with cheap but not worse reps, just mineral glass and so... St/ Yerebatan Cadessi nº 37/A. adn also Galery Boncuk.
