REFERENCE 5001 In the case of the Portuguese Automatic with date display, the railway track-style chapter ring, feuille hands and appliquéd Arabic numerals give the dial the classic appeal of the first Portuguese watches of the 1930s. The IWC-manufactured 51011 calibre integrates all the finest features ever to grace an automatic movement, such as the highly efficient Pellaton winding system and a seven-day power reserve.
