Best Swiss Patek Philippe Aquanaut Travel Time Ref.5164A Watch Replica

September 29, 2016

While BaselWorld 2012 Patek Philippe Aquanaut Travel Time watch replica from Patek Philippe in the past two years isn’t a Nautilus at all. You see, the Aquanaut has always been the other sports watch from Patek – considered by some “Nautilus light.” So it was with great pleasure that in 2011 we saw the launch of arguably the coolest Aquanaut to date, the Aquanaut Travel Time 5164A. The GMT hand is independetly adjustable via the pushers on the left hand-side of the case, making setting as easy as any travel time watch on the market.

Patek Philippe Aquanaut Travel Time Ref.5164A


Caliber 324 S C FUS has 294 parts, 29 jewels, and a power reserve of 45 hours.  It’s interesting to note that this is same power reserve as found in the non travel-time movement (324 S C) – one would expect the fourth hand and home/local apertures to take up at least some power.  But, these are automatic watches meant to be worn every day, so a power reserve isn’t a huge deal either way.

For the first time, the Aquanaut had a complication! And a good one! The 5164A is a casual Patek Philippe Aquanaut  copy watch with a second-timezone function shown via a fourth hand and two apertures on the dial that indicate whether you are reading local or home time.

At 6 o’clock is a traditional Patek Philippe date indication register tied to your home time. The case dimensions are 40.8mm, but due to to the case shape, it wears a little bit smaller (which is a good thing).

The dial on the Aquanaut is black embossed with gold applied numerals and luminescent hour markers, that could look very cool as this watch ages.  You will notice the date register at 6 o’clock has subtle globe theme – which is neither here nor there.  The bezel has your standard Aquanaut brushed finish, which is truly lovely against this black / grey dial

The movement inside the new 5164A is the caliber 324 S C F US, which is built atop the caliber 324 S C, that you will find not only in the larger Aquanaut model, but also the 5711 Nautilus – which of course prompts us to wonder “why not put this new travel-time caliber in the Nautilus?” That’s another question for another day, and this movement is finished as beautifully as you would expect any Patek movement to be – which is to say, it’s absolutely gorgeous.


The strap on the Aquanaut is composite rubber that Patek calls “Tropical.”  I’m not sure if that is an allusion to the “Tropic” straps found on many 1960s dive Patek Philippe Ref.5164A  replica watches, or if there is any technical similiarties here.  Either way, the strap does its job and looks the part.  On the underside, you will find an Aquanaut double deployant clasp.
