Cousin, help me see what kind of Omega this is. The constellation chronoteter on the dial is a constellation observatory series, right?

Positive solution, constellation observatory series.

There is a special edition behind the table, which is the number of each table and has no meaning. It's just the production number on the strap.

To sum up, it is impossible to judge the constellation, let alone give an accurate evaluation.

Reference: Constellation all-steel timely model 16000 or so, and all-steel machinery seems to be about 30000. I haven't paid attention to o for a long time, which may be inaccurate. Please forgive me if there is any mistake.
