Omega Seamaster Calendar – 2627 sc

Hi everyone,

I'm following this bid currently for a semaster calendar. I understand the the crown might no be original / a replacement. Here's what I would love your help with:

1- is the case in good condition/ not too overpolished?

2- is the dial in original condition/ refinished?

Is is a good buy for 1200usd – 14k solid gold.

Thank you!
