How to confirm if they're real or fake? Any certificate of authenticity or confirmation from the brands themselves?
Yes Of course, every brand is being sold via Authorized dealer. Each watch comes with proof of authenticity.
its hard to identify which one is the original because of our technology nowadays. They can copy almost 100% of the original one. Specially in luxury stuff they make it in their bussiness. The materials used was cheaper than the original one and they sell it expensive as original one.
