Released in four different versions, the Reference 26574 comes in stainless steel or rose gold, with either a navy blue or silver Grande Tapisserie dial. The case has been enlarged from 39mm to 41mm, making the dial and its indication easier to read. The 52 weeks of the year are indicated by an outer chapter ring with a corresponding central hand. The new, automatic calibre 5134 runs inside the watch and is visible through the case back.
