Need help identifying my Omega

Brand new poster here!

I bought an Omega when I admittedly knew very little about watches, just really liked the appearance of the below watch, pictured.

I have a box for it, no papers. Wondered whether anyone could identify it for me, beyond it being a Seamster Aqua Terra?

I never see these for sale so have very little sense of what it is worth - I am likely to sell it soon as I don't wear it enough.

Extra info:
36mm
18ct gold
About 9-11 years old from what I remember seller telling me

Thanks in advance!

Hey, I've seen this watch on the omega website : https://www.omegawatches.com/watch-omega-seamaster-aqua-terra-chronometer-26035037
although its a 38mm version. Hope this helps as it provides you with the serial number, but did not find any example for sale thus i could not provide you with the price of the watch.
