I’m not a collector but like a nice looking watch. Ultimately, for me, if it looks good, and isn’t a glaring redial at a glance, then it’s probably okay for my needs - that’s what I’d say about this one. If it was under £350, I might be tempted because it looks good, not £500. The experts can comment better than me on a redial - can’t tell if the sub dial has been painted over, possibly?!
No Swiss mark or is it hidden? I fear it may be a good or early redial. Whatever it does look nice. Get the case number and compare with others.
Looks like a redial to me, the subsecond doesn’t have any relief, so I think it got covered once with colour.
