The best way to get a valuation is to search for actual sales prices at auctions, on eBay, and in forum listings. Perfectly fine watch, but not amongst the most desirable Constellations to collectors.

Yes, it takes some experience and knowledge to do an appraisal. You need to learn how to find comps (takes practice), and then make adjustments based on condition (takes experience and knowledge). When I make the effort to look, I can generally find enough sales to determine a value. But it takes some work, so I think it's reasonable to do it for yourself and not ask strangers to do it for free. Or hire a professional.
I do my research, but other watch enthusiasts knowledge is valuable too. It’s just that sentence ”check eBay” that pops up all the time. Checking eBay has never really given me much confidence in determining prices. And the auction results on eBay? Ridiculous, imo.
I check Chrono24 and deduct 25-35%, auctions houses, pawn shop auctions etc. But there are regional differences. I’ve sold watches pretty much dead on the market here, fir full price to the continent. And vice versa.
Respectfully, I think you have a lot to learn. How are auction results on eBay ridiculous? They are auctions ... people bidding against each other. Auctions on eBay are extremely valuable data, and it's a large marketplace so I often look there first for lower value watches. Look in the sold items search, sort by value, and you can often get very useful information, even about best offer sales.
Auction houses and forum listings are also useful, especially for higher value watches. It can help to have login accounts at the auction houses and consolidator sites to view their sold prices, as well as watch charts and similar sites that archive sales data. Research isn't trivial, it takes some knowledge and practice, but you need to have a good attitude about it, and common sense.
On the other hand, deducting some arbitrary amount from C24 listings (or dealer sites) is silly and pointless, IMO. Some asking prices there are close to market value, and others are 3x market value.
If you or the OP wants other enthusiasts to help you, I'd suggest cultivating relationships with a back and forth by sharing information. Develop a network. Then, if you develop credibility, people will reach out to you for advice, and you can ask the same in return.
That’s a lengthy, bit snarky and patronizing response and jumping to conclusions.
But thanks anyway.

Haha, I just noticed this other thread where you are asking members to evaluate seven watches for you.
How dare we not give you free appraisals! It's so unfair!

Thread 'Seven Omegas, what do I have here? Valuation.' ·Curiosity hit me.

And?
The point is that this forum isn’t a free appraisal service. Watch prices fluctuate regularly. What may be true last year or earlier this year may not be true today. What may be true in Europe, may not be true in the USA. You’re essentially asking forum members, many of whom are busy and have jobs/families, to either guess or research the values of your watches. Sorry but that is not anyones job except yours.
After reading some of these replies it reminds me why i left a couple years ago, why people feel the need to reply with negative comments rather than just keeping quiet is beyond me, the comment from masteroftime is just baffling the whole perpose of forums is for people to share knowledge if i already had that knowledge i wouldn’t be asking and if i could find that out myself i would, but i dont know 10s of thousands of Omega enthusiasts to ask advise hence why i reached out here. It really does give forums a bad name and you really dont make people feel comfortable when asking for advice.
It's always appreciated when people first do their own research, an easy act of good faith. Asking the experts here, at almost no end, the value of this watch and that watch ... it's not their jobs, right? We can agree appraisal services can do that for a cost? And if you need the value of 7 watches you intend to sell that's probably the best route, if you don't have the knowledge base or inclination to actively learn. The members here are very knowledgeable and more than happy to give advice, I have learned a lot myself. Take what they give you as an addition to your own research.

What do you mean by authentication papers BTW?
It looks like a nice original gold cap watch in good condition, I think you will realize between 800 and 1000 USD on EB if you take lots of good quality photos and describe it well. Maybe more. I would list as no reserve starting price 1.00 and let it achieve market price. Many Omega constellation collectors out there and many others just looking for a nice looking vintage watch.
If you are not in a hurry and want to put a fixed price on it you can try Chrono24, but if you put even a slightly high price it will likely sit for long time as collectors know the market.
There are many new members who make "fly by" appearance asking for appraisals without doing any sigificant research on their own, and this is not well appreciated as you can see. Don't take it personally. Good luck with sale.
