Seamaster Calendar opinion

Hi guys,
I’m looking for a Seamaster calendar with date at 6, I think one of the most underrated Omega’s references at the moment.
I found this example:
Ref 2627-1
Cal 353 bumper
SS case with a decent shape (it not seems too polished for my poor experiences)
Wrong crown (and seems after market)
Nice original and aged dial
Made in 1950’s from the serial number
Original glass with logo
The price request is 700€.

What do u think about its conditions and price?

Thank u so much for your time 🙂

I think it’s a nice watch and a fair price. Crown shouldn’t be too hard to find.
