Patek Philippe Aquanaut, commonly known as “grenade”. In Patek Philippe’s on-sale series, there are two major sports models, one is NAUTILUS and the other is AQUANAUT.
Patek Philippe launched the Nautilus in 1976 and the Aquanaut in 1997. Patek Philippe Nautilus is a luxury sports watch that combines sports and formal wear. In the words of Patek Philippe, “it can be matched with a diving suit or a tuxedo”. At the same time, the Nautilus was designed by Gero Zunda, not Patek Philippe itself. Therefore, Patek Philippe decided to launch Aquanaut.

It is currently recognized that the first watch in the replica Patek Philippe Aquanaut series is the 5060A launched in 1997, with a size of 36 mm. Although in 1996, Patek Philippe launched a gold shell 5060S, but because the 5060S has obvious nautilus features, it does not have the characteristics of a modern Aquanaut on the disk, and it uses a belt and no tape. So the 1997 steel-hulled 5060A is considered the first Aquanaut.

Patek Philippe 5065 and 5066 are the first mass-produced models of grenades. Someone may ask, why are there two models, 5065 and 5066? Because the size is different, one big and one small. The 5065 is 38 mm, and the 5066 still maintains the original 36 mm. From 5065 and 5066, Aquanaut is officially independent and becomes the Aquanaut series. In 2007, Aquanaut was updated, and now Patek Philippe is selling Aquanaut 5167. Compared with the previous 5065, 5066, 5167 has changed a lot from the inside to the outside (the 5165 was launched at the same time as the 5167, but the 38mm 5165 was discontinued after 5 years).

The size of Patek Philippe Aquanaut 5167 has been increased to 40 mm, which is in line with the current trend and is of moderate size. The dial of the watch has changed from the previous “square grid” to “square shape and dashed lines”. Although 5167 still uses the time scale with squares and numbers, the time scale at 3 o’clock has been completely replaced by the calendar, without the number 3. 5167 uses the Patek Philippe 324 automatic movement. For many players, 5167 has become an “alternative” to Nautilus. Although Aquanaut was originally positioned as a pure sports watch, because of the changing trends, Aquanaut is also sporty and formal wearable.

In 2011, Patek Philippe launched Aquanaut 5164. 5164 is the GMT model of Aquanaut, with a steel case and a rose gold case, and a size of 40.8 mm. 5164 adds two buttons on the left side of the case to operate two places. The two buttons on the case form an arc, which is symmetrical and coordinated with the crown shoulder guard on the right side of the case. 5164 also uses 324 automatic movement. In 2017, Patek Philippe launched the large-size 5168G. The size of 5168G has been increased to 42.2 mm, which further fits the current trend of large watches. There is only one model of Patek Philippe Aquanaut 5168G, which is a platinum case with a blue or green dial, and there is no steel model. Therefore, the advent of the large 5168G will not affect the steel case 5167. 5168 is also a 324 automatic movement. In 2018, Patek Philippe launched Aquanaut 5968. 5968 is the chronograph model of Aquanaut, using Patek Philippe CH28 automatic chronograph movement. The biggest appearance feature is that it uses orange color, the central chronograph second hand, 60-minute chronograph dial at 6 o’clock, and the dial scale are all orange. Plus it comes with orange tape for a stylish look. More replica Patek Philippe Aquanaut watches.
