1977 Seamaster (quartz) - Authentic?

My first post here, so if this is the wrong spot for it, please feel free to delete or remove it. I recently purchased this quartz 1977 Seamaster on eBay for $320 USD (which, according to the Interwebs, is about 245 GDP or 430 AUD) from a seller who is local to me and offered a 14 day return guarantee. I'm still in that return window, so wanted to try to confirm authenticity as best I can and make sure I didn't overpay. The seller has a good reputation on eBay with a lot of sales, but mostly sells second hand jewelry. I got the sense that they probably don't know much about watches or about this watch's authenticity (hence the return guarantee).

Since receiving it, I've researched as much as I can. The watch has a lot of markings/numbers that seem correct and that I have attempted to photograph. I have only found two other examples online, though, of ref. 196.0072 with a grey dial (rather than white) and the word "Quartz" appearing near 6:00 below "Seamaster," rather than near 12:00 below "Omega" (and the two examples were just other watches that had been sold second hand several years ago).

It's a modest watch as far as Omega's go, but I love the style. I'm hoping to confirm everything looks correct and find out whether it might be a redial, as well making sure I paid a fair price. Thanks for taking a look, I appreciate any information, opinions, or red flags.

Watch looks fine, that movement is pretty fragile though so handle it with care. The bracelet seems a bit "modern" to me but looks the part.

Thanks, that's good to know.

Thanks, appreciate the info. I haven't found much info on the bracelet. It looks like one was for sale on this forum a while back, and there is one currently for sale on eBay that lists it as being from 1970. Though, that only tells me that some random person claims it is from 1970, so can't put much stock in that. Is there any source/reference out there that is helpful for identifying bracelets?

That's great to know. Thanks much!

Nice vintage band to match. Congrats...

Thanks!
