I had a quick look on Facebook (?) but couldn’t see it, and you haven’t mentioned anything about price or what, if anything, the seller asserts.
I'm responding in a little more detail than I normally would because threads like yours may be read by other new watch aficionados and this may help them, as well as you.
First, you may find it helpful to read:

This is a useful resource that helps all buyers, particularly new vintage watch fans like you.
It’s regularly said that with old watches, you have to buy the seller as well as the watch. The absence of information or of movement and caseback photos suggest that unless the seller is completely unaware of the condition, you shouldn’t buy the seller.
The premise is also that if they have posted good photos on a website like Facebook, then they’re not grieving relatives selling grandad's watch.
Further, many watches of the age of the one you post have been re-painted at some stage. This significantly reduces the value of the watch, at least to a collector. I can’t say from the quality of your photo if this one has been re-dialled but I’m assuming it has been.
It’s a gold plated watch, the crown looks wrong, it probably isn’t serviced and parts may be hard to source. You don’t say if it’s running (accurately or otherwise) and a service will cost you around £150 plus parts if the actual movement is running.
So, unless you’re in love with it (and you say that the 'price isn’t your concern') or you fancy a gamble and you can afford to speculate for under £150, on the information you’ve provided, I wouldn’t go anywhere near it.
