First Vintage Omega, Looking for Opinions

Hey there, new member here.

I recently purchased my first Omega (and my first vintage watch in general) a few months ago off eBay.
It has been recently serviced, runs well, and keeps good time.

Based on research I did from the serial number off of the movement, it's a Cal. 266 from ~1952-1956, hand winding mechanical movement. I couldn't find any other Omegas of this caliber with a similar watch face so I don't really know how much it's worth. I paid about 400 USD for it.

I don't know too much about what would tell me if it's 100% authentic or not, besides the small amount of research I've done on these forums and other places online. I know the crown isn't original, which kinda sucks.

Basically what brings me here is I'm wanting to know people's opinions on if it's a fake, and a ballpark estimate on how much it's worth. I have absolutely no intention of ever selling this watch as I love it and wear it all the time, but if I were to get it insured for example I think I might need to know how much it's worth.

Also, when I wind it, I can usually get up to ~15 "winds" before I start to feel resistance. Is there any risk of damaging the movement if I over-wind it?

Anyways, thanks for your time reading this, if people require other photos I'll do what I can.

It's a redial.

That alone destroys most of the collector value.

Can you or someone else elaborate on what features distinguish it as a redial?

Also, is a redial just when they re-paint the dial part?

Hello and welcome, it's sadly a redial, you can see it best on the subsecond. Compare the one in the
picture with yours that has no circles.
And there are other details that are off.

And yes, you can overwind a mechanical watch.

The easiest tell IMO is the black paint climbing up the hour markers. The good news for you is that no one except watch nuts will ever know the dial finish isn't original. You can see it in one of two ways - distinctly expensive for a vintage Omega, or distinctly cheap as learning experiences go.

Great watch for daily wear. It’s just not as collectible. Enjoy it.

Even disclosing the redial someone will probably pay over 300€ for it on ebay, most people don't give a damn if it looks "pretty" and shiny.
