L'Atelier D'Horlogerie

All items on LUXE & EM are put through a multi-dimensional authentication process. We inspect all goods for brand marking, date code, heat stamp, serial number and hologram stickers. Every detail must be checked under strict scrutiny before it is curated into daily sales.

Our watches are authenticated and appraised by our master horologists at our atelier and each piece comes with one year guarantee starting from the date of purchase. Jewelry items are thoroughly researched and validated by using the technical equipment at the lab which allows us to see details unobservable by the naked eye — details that are crucial in determining authenticity and value.
