Need advice on a watch!

Hey guys, I need some help with this watch I recently purchased in online bidding from private seller.

I'm seeing its a 166.002 on the case back but to be fair it doesn't look exactly like the other models online and I don't know why that is. I'm not sure if its normal or not but I don't see a swiss-made symbol, it seems that the hour markers are slightly misaligned (to the left) to the minute markers. It would be super helpful if people let me know what they notice about the watch, or any tips! Should I get it serviced, and is it worth the price i'd pay?

Overall it runs super smoothly and find it really beautiful! This is my first watch so not familiar at all with movements and designs but definetely looking to get more into it.

Would also be keen to hear how much people would be willing to pay a watch like this - to see if i got scammed haha!

Drunken magic marker application?

Also escape wheel bridge is from another movement of the same cal or a service part. The plating doesn’t match.

yea absolutely, kind of an impulse buy but now aware of the help on here!

No indeed it wasn’t disclosed, will see what I can do regarding return. It was only 450 euros so I guess it’s still reasonable as parts look nice.

Yes, I did have worries, but was mislead by the description. To be fair I don’t have any watch buddies and wasnt really familiar with subs like this. But gotta make a mistake once to learn
