The photos are very poor and there are no photos of the movement. You should post more and better photos. Also it helps if you disclose the price. Frankly, looking at the photos you have posted, no one here will be interested in beating you to this watch.
The dial may be okay but hard to say with your photos. The gold plated case is, at best, very tarnished. The hands and crown may be okay.
If the seller has taken as much care of the watch as he has of his photos, you’ll need to factor in £100-130 for a service.
So, if the seller is asking £200 or less, it might be worth taking a chance and buying it.
A perfect example, and yours doesn’t look it, might be worth in pristine condition, about £350, £400 tops.
This is mine, for you to compare, with a 552 movement and serviced within the last year or so, probably worth £400
