I have been offered a T Serial black dial 16520 in good overall condition, no box or papers but from a trustworthy source.
Any ideas of value? Watchcentre seem to put a premium on Zenith Daytona's but maybe these are rarer 'tansitional inverted 6 models etc' or 'Patrizzi dials' I don't really know my Daytona's. Are these more valuable than the modern Rolex movement and updated clasp models?
Any assistance would be appreciated.
Regards
Jacob
