The watch is slightly larger measuring in at 42.2mm, compared to the traditional 40mm case size, and the model is now composed of solid white gold instead of its signature steel construction. HODINKEE points out that is just the second version of the 5168G model, while the first and original version in blue debuted in 2017 to celebrate the Aquanaut's 20th anniversary.
The website also states that the arrival of this green version is actually significant since the original green-dialed Aquanaut, ref. 5167A in 40mm stainless steel, was extremely rare with a production of less than 10 units, and were made just for special clients sometime during 2010/2011.
In terms of what's inside the case, the watch boasts the same movement with the calibre 324, a three-hander with the date at 3 o’clock, the Patek seal and -3 / +2 seconds per day accuracy. The movement is also visible on the back, which beats at 4Hz and boasts 45 hours of power reserve. Lastly, the watch is paired with a matching green "Tropical" rubber strap that features a folding clasp.
The Patek Philippe Aquanaut 5168G in "khaki green" retails for $35,000 and will be available to purchase at Patek Philippe boutiques and online later this year.
