Vacheron Constantin Fiftysix complete calendar 40 mm Silver Dial Stainless Steel Leather Strap 4000E/000A-B439

Heir to a model from 1956, this steel watch features a precision moon phase that is accurate over 122 years. This poetic complication is finished with day, date, and month displays. Embellished with blue, the date hand and the moon phase disc contrast elegantly with the silver-toned dial. Its openworked caseback reveals an elevated oscillating weight in 22K gold, inspired by the Maltese cross.
