Ruud van der Knaap, commercial director, is delighted that GASSAN Diamonds is officially linked to Feyenoord from the 2025-2026 season. 'The bond between GASSAN Diamonds and Feyenoord goes back a long time and is ironclad. Owner Benno Leeser stood at the cradle of the Feyenoord Business Club and was its chairman for many years. And when there is something to celebrate, GASSAN likes to think along with us. We look forward to working together on great projects within the club in the coming years.'

Industries fit together
Benno Leeser, owner GASSAN Diamonds: ‘We are a primal Amsterdam family business and I myself am a born Amsterdammer. Yet I have been a fanatical Feyenoord supporter all my life. I have been coming to De Kuip for decades and rarely miss a home game. So for me personally, it is great that we are now officially associated with the club. But it is also a great step for GASSAN Diamonds. We work with many professional football clubs, our industries fit together. I hope we can celebrate many sporting and business successes together in the coming years.'

Official Timekeeper
Part of the partnership is that GASSAN Diamonds will be Feyenoord's Official Timekeeper for the next few years. As such, the jewellery house will be visible on various time elements during home matches at De Kuip in the coming years, such as on the scoreboard and the LED boarding. This involves a project-based collaboration with watch brand Breitling.
