Asking $5600.
To pay that amount, I would expect a good condition watch running well and without problems - OR a lesser condition watch with another good reason to pay the high price. For example a one owner history.

Now I am not trying to say look how clever I am (I am not it - was an open auction) just that see the difference for $2000.
I believe it is often better to pay less for what might initially look like a basket case, but be in control of how it is brought back into commission. Rather than pay a high price for a dubious history that may turn out to be hot air, and need that $600 anyway.
The OP watch might look really nice - I suspect it does, but the photos are not giving me what I need to be sure.
The dial might be clean and attractive - but only one photo shows that, the rest show a washed out dial. Could be the light.
The bezel is good in place and bad in others. Not great, not what I think of as a bezel that could push the price.
The hands are correct, these chrono hands were fitted toward the end of production. However they look dirty or grey.
So much depends on service history and actual appearance in natural light, and if those hands look ok or not, and if the dial has a nice colour to it.
On the evidence presented, its more money than I would pay.
However I could see that it might be if there was a better photo showing an attractive dial, hands that matched, the bezel went with the rest of the watch, and that it has had a recent service.
That's a lot of "if"s
