Omega Constellation 14381 Originality Check (c.1961)

Hi,

I'm relatively new to vintage watches and thinking of buying my first Omega Constellation. I've been reading through this forum for a few weeks and trying to learn how to fish, but would love a second opinion on this ref. 14381 with serial number 1803XXXX (~1961).

The lugs/bezel look sharp and mostly unpolished to me. From my research, the text on the dial also looks correct for this reference and I think the dial and cross hair are original, but not completely sure.

Do you think there's anything I should be concerned about on this watch? The 3 o'clock lug looks a little crooked maybe, but I'm not sure if that's the camera angle. Would around $1500 be a reasonable price for this non-dog leg version?

Thanks

Thanks everyone! Here's a picture of the case back but it's a little hard to see. I'll see if I can get more photos.
