Gassan 

Built in 1879, Gassan Diamonds is Amsterdam’s oldest diamond factory. It is also home to a Rolex Boutique, where visitors can delve into the magical world of this famous Swiss watch brand via an exclusive Gassan VIP Tour. After enjoying a welcome glass of champagne, guests are led through the historic factory and learn about diamonds and the craft of diamond polishing; visit the Rolex Service Workshop to see Rolex-certified watchmakers at work and hear more from the experts there; and view the Rolex collection. And should anyone already own a Rolex, they can have their strap cleaned for free. The Gassan VIP Tour costs €35 per person (maximum six people per group) and also includes a unique Rolex goodie bag.
