The atelier’s Ultimate Vingt-8 announcement set December 31, 2025 as the final date for orders involving the movement and its related models. That deadline has passed. It should not be presented as a current buying opportunity or as proof that every outstanding watch has already been delivered. For collectors researching the family, the announcement is a useful primary document marking a production transition. It also illustrates why product announcements, order books, delivery schedules and secondary-market availability need separate treatment.
