Movement 5711 v. 5712

[josephvman]

I've got an Aquanaut, so I'm pretty familiar with the characteristics of the 324 SC movement, though I've not had to have mine serviced yet.

Does the movement in the 5712 have any quirks or require any additional maintenance? Is it a hacking movement? Anything else interesting about the micro-rotor in the 5712? Any problem areas or strange characteristics to it?

[GB-man]

Not hacking so let’s get that out of the way.

I’ve never had the pleasure but I’d love to own one. It’s much more pleasing to the eye than the 324! Been in service for a good long while so no hiccups to be concerned about

240q is a beauty...5712 was the only nautilus with it and Patek uses same base movement in other watches including 5131 and other world timers.

Now 5740 will have the same base caliber too borrowing from its traditional perpetual calendar line

Another reason I like my 5712a better than the 5711a.....the 240 micro rotor is just beautiful and unique on the 5712.....you can see so much more of the movement as well versus the 324 rotor plate on the back of a 5711.

240 is possibly the best looking movement in micro rotor category. Much better than 324 looks wise

Both great movements, both old and non hacking, both due for replacement. Depends if you need centre seconds. My PM 240 is a much noisier movement (rotor) than my PM 324 but this very much depends on the case material.

Yeah I also agree the 240 is more beautiful than the 324. Not to say 324 is not pretty, but the 240 is just on another level.

I prefer the 240. It’s more interesting visually and the micro rotor allows you to see more. It’s my favourite looking movement for sure of what I own. It’s not datograph nice though

The 5712 does not have a seconds hand. So I would say that is a significant factor for some people. However just like the 15202, most people probably don't mind not having a seconds hand.

There is a seconds hand, just not at the centre.

That is correct. Seconds hand is off to the side at 4-5 o'clock area, which is an unsual place for a seconds hand. But the 6000/6002 Calatrava has it at the same place, which also has the 240 movement.

240 is a much more interesting movement and visually pleasing to the eye. 324 feels somewhat generic. Large part of the reason why I'm head over heels in love with my 5712!

Non-hacking doesn’t bother me with a small seconds hand, so it’s fine. The 240 movement is a thing of beauty. But even more so is the dial.

To the OP the maintenance on the 240 vs 324 is the same no add additional maintenance required.....

As other mention no hacking....

The only down side to the 240 movement on the 5712 is 60 meters water resistant vs the 324 movement on the 5711 which is 120 meters water resistant....

Agree & no doubt the 240 look nicer because you get to see more of the movement....

But the 324 have more GOLD...lol... Thanks to the big rotor.....

Not to be that guy but the 5712 has the 240 PS IRM C LU movement, not the 240 Q which is a perpetual movement used in e.g. 3940.

As you write it is the same base movement, 240, but with different modules.

As you also point out the 240 Q is used in the 5740.

I’m sure thomas won’t mind. This is afterall the place to be “that guy” as we obsess over the smallest of details.

Wish my 5711 had the micro, so cute.

240 Q:


240 PS IRM C LU:

Visually they are almost identical. I know the q has the PC modules but most remarks here were about the looks of the movement which is not different between the Q and LU units

That is correct. I love the 240 and has it in thee different references. The only drawback is that it does not exist in a version with central seconds hand.

[Calatrava r]

Well the good news is all the 240 base movements look the same from the back are, therefore, equally awesome.

The only thing I would say on the 5712 is the dial is incredible but the movement with external correction lowers the water resistance substantially somewhat defeating the Nautilus concept. On a rugged water proof sports watch, to me, less is better, so I only have the 5711.

The 5712 movement is bullet proof and has been in the line for years in many dress case iterations. It took off in the 5712 against the blue dial.
