Heuer Autavia price?

Hello.
I'm fom Portugal and I have a tag heuer autavia that i believe is a 2446 M, second execution.
It bellongs to my father (watchmaker for more than 50 years).
I'm having dificulties in avaluating the watch and possible seling him...
I saw other watches in the Internet and values but i'm not sure if its this model.
Can Anyone help me?
Thaks.

I'm sorry for the mistake in the original post.
Like i said it's my father watch and i'm not an expert in the matter. I'm Just trying to help him in avaluating this watch for sale.
Thanks for the help.

This is fairly simple to evaluate -- you are correct that this is the First Execution Autavia Reference 2446, with the second execution dial (sometimes called the "Dots and Dashes" dial). You can see this execution here -- https://www.onthedash.com/chronograph/autavia-2446-second-dial/ This is a well-known execution of the Reference 2446 Autavia.

At the peak of the market for vintage Heuer watches (say, circa 2017), this watch might have sold for $30,000, assuming that the watch was all original and in excellent condition. In the current market, I suspect that the watch is worth about half that amount -- say, $15,000, in top condition.

I'm happy to follow up with any additional questions, etc.

I will try in Portugal but the marketing its bad. Im thinkin to pu'it on chrono24 and see how ir goes for a literatura less because its not in perfect condicons.
👍👍

You will want to be careful with Chrono24 - fees, taxes and tariffs can add significantly to the price of the watch.

In your opinion what is the best way to sell this watch in the correct price?

I would list the watch for sale here and also in various vintage Heuer Facebook groups -- there are several Facebook groups where the vintage Heuer collectors hang out, and transacting with other participants is relatively easy (and safe, if you are careful).
