Newbie trying to find his first vintage omega

Hey folks, first of all i´m really happy that i found this forum.

I´ve been looking for my first vintage omega (and first vintage watch in general) for quite some time now.
I´ve already nailed it down to two models.
Either a 1960s-early 70s Seamaster De Ville with a steel case and a silver sunburst dial (preferably with a crosshair but not a must have) or a dogleg Constellation also in steel with a silver dial.
I´ve mainly been looking on Chrono24 and Ebay so far. What i noticed: on Chrono24 the prices seem higher in general but therefore a lot of the watches are newly serviced and quite often come with warranty. Do you guys think it makes sense to only buy from professional dealers and pay the extra amount or would you also consider buying from private sellers on ebay to save sometimes a huge amout of money. My maximum budget would be around 1600€ (I´m from Germany btw) does that sound reasonable? How much does a service cost for these old omegas approximately? Are there other reccommended places to look for these watches?
Sorry for so many questions at a time but there is quite a lot yet to learn for me.

Here are two examples of price wise different watches. Maybe you can let me know what you think of them.

Is this one from Chrono24 overpriced?

I noticed that the bezel seemes broken but this is the exact dial i was looking for mainly.

Thanks in advance, Jan

Thanks for the answer! I can´t find a single SMDV that is still for sale at the private sales section here. Is this because they normally sell super fast or am i searching wrong?
Good to Know. I will study these threads.

@ErichKeane thanks for confirming that these watches are not the best deal and for showing some alternatives. They actually seem way more trustworthy. Though i am very sure about the stainless steel case and silver/white dial and hands. I´m just not a big fan of gold in general (unpopular opinion, i know). I was mainly looking for the SMDV because i just like the simple elegance and i think it is very timeles. The price was not really the reason.

Hey Folks, i read myself through the "learn how to fish"-thread.
Today i got a very spontanous offer.
This watch costs 350 €
Appart from the scratches at the case and the lugs i can´t see any visual problems with this watch.
the only problem is that it had not been serviced since 2006.
What do you guys think about this offer and the pictures?
Are these hands original? Since i haven´t seen these triangle hands on a Seamaster de ville before.

Thanks for confirming that the hands seem wrong. What exactly is suspicious about the sunburst finish?

I might have the chance to take a look at it since the guy selling it lives only half an hour away from my place. though i am not sure if i´m able to tell wether it is original in person since i have no comparison. The price is quite tempting to at least take a look though

A good way to know if th hands are not for that ref is in this case they have a black onyx strip on them but none of the indexes do. Generally they will have them as well.

@TIMElyBehaviour makes sense. Thanks for sharing your knowledge.

Today this watch was uploaded to C24:

Maybe you guys can tell me your opinion about this example.

Compared to a lot of similar watches on C24 it is a bit cheaper. Though still not very cheap. The seller has been around for quite some time now and has a lot of positive reviews. He´s specialised in vintage omega.
What i noticed: The dial, the hands, crown etc. all look authentic to me.
It says "SWISS MADE" on the dial but without the "T´s". Not sure if that would necessarely be a sign of a fake dial?!
Is the polishing a no go?

@Dan S Thanks for the quick reply once again. So the "T" stands for the Lume?
