The white gold Nautilus Perpetual Calendar reference 5740/1G is the first ‘Grand Complication’ to be introduced to the Nautilus collection. Combining the sporting appeal of the Nautilus with the technical sophistication of a perpetual calendar, many collectors consider this model to already be a modern classic. The present example is preserved in very good overall condition and is accompanied by its full set of accessories.

The reference 5740/1G Nautilus Perpetual Calendar is a fascinating creation with recognisable ancestry from not only the Nautilus model itself but in using the famous ultra-thin automatic caliber 240 Q movement Patek Philippe have immediately connected it to some of the great perpetual calendar watches of the past, such as the reference 3940. The layout of the classic blue Nautilus dial with horizontal ribbing, applied luminous indexes and hands is also a familiar Patek Philippe design classic, with the month, day, date, leap-year indication 24-hour indication and moon phase. The solid white gold 40 mm. case is perfectly sized, being neither too big or too small and has the brushed and polished finishes that make the most of the play of light across the surfaces. The model is completed by the solid white gold bracelet with Nautilus fold-over clasp.
