About the Fiftysix family
This heading holds further references from the Fiftysix family, written with a capital S in some sources, including the steel and pink gold self-winding, day-date and complete calendar models such as the 4600E, 4400E and 4000E.
The line was introduced in 2018 and is inspired by ref. 6073 of 1956, with lugs shaped after the Maltese cross. Dealers identify the function and metal from the full reference, as in the main Fiftysix heading, and check the strap, box and papers.
