JHP stands for Jean-Pierre Hagmann, and Svend Andersen is one of the great names of independent watchmaking. When a watch made by Svend carries a case stamped JHP, it deserves to be regarded as a grail piece.

Svend Andersen is a founding member of the AHCI and one of the finest watchmakers of his generation. Jean-Pierre Hagmann was one of the great casemakers, responsible for some of the most celebrated cases made for Patek Philippe, among them the 3974, 3979, 5016 and the Star Calibre. The two worked in close association and were close friends.

Jean-Pierre Hagmann died on 7 March 2025. We were fortunate to know him, not only as the finest casemaker but as an exceptionally kind man and a friend. We hope Svend will be with us for many years to come, to create more watches and to join the legendary dinners in Geneva, where the old stories are told.

It is from the past that we learn for the present and the future. Craftsmen like Jean-Pierre and Svend should not be forgotten, and anyone who has the chance to spend time with them should listen to every word.
