The ref. 5135 was introduced in 2004 and remained in production until 2011. Made with incredible attention to detail by Atelier Réunis, it uses one of the most complex cases constructed in the 21st century. Its large size and ‘useful’ complication of an annual calendar make this an interesting value proposition to the modern collector.
