From memory, with a bracelet and in strong condition, I have seen them go around 500€.
Yours is tough to properly evaluate on condition with the blurry pictures. The dial may have marks and spotting, but it could also be mostly on the crystal - hard to tell. Equally the case shows some worn facets, and it’s hard to discern the lines that are a key feature of the reference. But they might be there. So I would pay an average price for this, factoring something less for the bracelet. In any case, still higher than 100€ which is literally a give away.
Just bear in mind service can cost 200-400€ if the watch isn’t working well or if you want to wear it daily.
