Welcome to OF
@david84
A pretty good watch for a first buy as
@kaplan says.
I have a fondness for this style of Constellation so congratulations on your new watch.
Good looking dial, very good case too.
IMHO the added Meister doesn’t add value but some like it and are willing to pay a premium for it.
The 168.004 was the first hidden crown Constellation ( strictly speaking there is an earlier version but .004 is generally held as the first)
It was first produced from 1962 but was really released in 63 and ran through to about 1967.
The cal 561 has a semi quickset date.
Do you have any additional information on the watch , like the movt serial number?
I ask because the dial is unusual in that it appears to have notches for lume at the ends of the indices but no Ts on the dial.
This did occur on later (70s) watches but not so much on 60s watches unless very early -like 62/63.
Nothing about the dial suggests it is otherwise incorrect but it is a bit of a conundrum
