Launched in 1976, the Nautilus today is more than just a popular sports timepiece - it is a cultural icon in itself and a cornerstone in Patek Philippe's catalog. Following the launch of the reference 3700/1, the model has re-invented itself in many iterations such as changing the dial colour or including complications. 

By 2018, Patek Philippe had diversified its Nautilus line up to include a vast array of complications – from a simple date to a chronograph to an annual calendar. As such, it finally came time to introduce one of their signature complications - the perpetual calendar - in the Nautilus line, and at Baselworld Patek Philippe launched the 5740G. With a lustrous 18K white gold case and bracelet, the caliber 240 Q – Patek’s ultra-slim perpetual calendar movement stamped with the Patek Philippe seal – beats within so that the case itself remains a mere 8.42mm, which is even slimmer than the reference 5712.

This immediately captivated the market with its combination of sporty/elegant aesthetics boosted by the incredibly attractive and refined metallic navy/royal blue of the dial and the intrinsic scarcity dictated by the complex movement. Combining all of the above with the practicality of an automatic perpetual calendar - theoretically ensuring no need to set or wind the watch, assuming one always wears it, until the year 2100 - results in what some consider the ultimate Nautilus, an “everyday grail” equally suitable for a charity gala as it is for scuba diving in the Caribbean.

Preserved in excellent and barely-worn condition, the present watch is accompanied by its Patek Philippe Certificate of Origin dated December 01, 2022, product literature, wallet, presentation box and outer packaging.
