Heres my new swiss ETA PO which cost me $159, amazing quality when you feel it in the flesh...has real sapphire crystal with AR coating also. You simply wouldn't get a genuine watch of this quality for less than £400 imo.
if that has an eta 2824 then its worth the money for the movement and case, tho i would scrap the dial and add a bill yao one,,sapphire crystals are about a tenner,for £400 you can get a hell of a better watch that is not a replica.
,vintage omega prices have gone ballistic,imo the best ones atm to collect and for the future pricewise are mechanical seikos ,vintage seikos are also fetching very good prices at the moment -if you can find them cheap at boot sales,esp the divers models and old chronos.
