A heritage Maison since 1912
History
Since its founding in 1912 by Jean-Pierre Kayser, the Maison Kayser-Reinert has embodied fine jewellery and watchmaking craftsmanship in Luxembourg. From its beginnings in Esch-sur-Alzette, the family house grew over generations into a distinguished address: 46, Avenue de la Liberté in Luxembourg, a place that continues to reflect elegance, excellence and artisanal savoir-faire.
Carried forward by Jean Kayser and later by Norbert Kayser and Monique Reinert, the family business has preserved its values while continually refining its expertise. Today, Kayser-Reinert brings together tradition and contemporary refinement, with the same attention to detail, the same care in selecting each piece and the same trusted relationship with every client.
Craftsmanship & personal guidance
At Your Service
At Kayser-Reinert, every client is welcomed with attentive, discreet and personal guidance. Whether you are looking for a piece of jewellery, an exceptional timepiece or a gift of lasting value, we accompany you with experience, sensitivity and the highest standards. Our selection includes carefully chosen pieces from renowned houses such as Chopard, Breitling, Longines and TAG Heuer.
In our ateliers, qualified goldsmiths and watchmakers carry out the care, repair, adjustment and restoration of the pieces entrusted to us with the greatest precision. Each intervention is performed with respect and meticulous attention — for a lasting service worthy of the elegance and standards of Kayser-Reinert.
