I have started to have an interest in watches lately and I have been looking to buy a first watch. Today as I was roaming this piece caught my eye. It is a 1970 omega constellation chronometer officially certified spider dial. It does not have any box or certificates. The seller is asking for 800 euros, what do you all think ? Should I grab it for that price and is the watch worth buying ? I personallt absolutely love the dial but it being an old watch has confused me. Thank you all for your help.
