which one do I like more?

Sometimes on Sundays there is an empty moment and I had it today. I took out both of my Nautilus sisters and tried to understand which one I like more - forgetting the case construction, rarity and value.

Here are the two sisters:

On the left is 5712 and on the right 3712. Look at the bracelets. The one of 3712 is somehow "finer" and more flexible.

Then I wanted to check the thickness of the case. Officially 3712 a little bit thinner but what is the situation in reality.

Here is 3712:

Never mind how many times I measure it, the thickness is 8.87 mm.

And 5712:

It is thinner! In reality 8.87 mm vs. 8.63 mm.

But what about the weight?

Here's 3712:

And here is 5712:

So in reality 5712 is 2 grams heavier than 3712. No difference in reality.

The shapes of the watch cases are a bit different and so are the dials. Looking from the left.

3712:

5712:

And from the right.

3712:

5712:

My verdict:

If we forget the case construction, the differences are very small. If we forget the rarity and value, the differences are basically non-excisting.

But which one, just as a plain watch I like more? If I would have both in front of me and I would not know what the watches are, I would most probably pick up 3712. Why?

- The dial of 3712 is somehow more "sober".

- The bracelet of 3712 feels somehow "finer" and it is more flexible.

But again, if I would not know the watches and I would be asked: "would you pay 10% more for your pick?", my answer would be NO!

What's your opinion?

Best,

Kari

Key Points from the Discussion

The 5712 is preferred for its bolder presence on the wrist, despite the subtle differences between the two references.
The author's measurements revealing the 5712 as thinner and heavier than the 3712 were unexpected.
The 5712's more rounded casing and dominant date/moon phase complication are preferred by one contributor, while expressing caution about measuring directly on the case.
The 3712 is considered a good investment due to its original case construction, rarity, and low production numbers, suggesting future appreciation.
The 5712's rounded hinge and crown side are preferred over the straighter versions of older references like the 3712, contributing to its appeal.
The smaller subdials and thinner hands of the 3712 are seen as more elegant, fitting its overall thinness and comfort.

Amazing post

I would never have guessed the 5712 would be thinner and heavier! If I was completely unaware of rarity and asked to pick one to go I would have grabbed the one closest to me hoping the offerer would not have time to change his or her mind But if it was a real offer based on me rationalizing the choice, I probably would have gone 3712 simply as dial is more sober, as you noted. But agree differences are so subtle. Love the fact that you have both! I suppose you do not like to take the easy path.

In the morning I will

take from the winder the one my eyes are hitting first. There is no real difference on the wrist. But in a way I would compare 3712 vs. 5712 to 3940 vs. 5140. The newer models are a bit bigger but when the sizes of numbers were increased on the dials, the watches lost something from their elegance and the dials become more crowded and messy. But that's just my opinion. Best, Kari

It's a bit of a coin flip for me ...

But with a slight nod to the 5712. I think the differences between the 3940 and 5140 were more stark, with a resulting loss of elegance in the 5140. Comparing the 3712 and 5712 though, I think the sporty nature of this watch suits well the 'upgrade'.

I would be happy with either or

and if I would know nothing about 3712, I would call 5712 "perfect". Best, Kari

So subtle differences...

...that I can't tell there is one that I prefer more than the other, and clearly no I would not pay the present premium for the 3712 today. Am I mistaking about the 1 red dot difference in the reserve de marche ? 3 dots for the 3712 and 4 for 5712, is it correct? I am not sure on the pics, Best, Mike

I'm not sure but weren't there 2 versions of the 3712? One with 3 and one with 4 dots?

Or am I mistaken between the 3712 and 5712? Anyhow: I would pick the 3712. The dial is more balanced and that extra tiny lume index gives it a little quirkiness. Wish I bought one before the price explosion.... #fail
