Condition: This watch is unworn in near-new condition with very minor shop-wear. Originally sold out of the original authorized dealer as a display piece. The watch was running slow, hence we sent it in to Roger Dubuis for a factory service, which was completed in 05/2026. We would be comfortable rating this watch in 99%+ overall condition. Delivered with a generic Roger Dubuis box, a Roger Dubuis archival certificate letter, and a copy of the factory service documentation. PLEASE NOTE: There is some deterioration/peeling of the black vinyl box interior, particularly on the cushion insert, which is typical of vinyl lined boxes.
