    I am sorry but I can't say much since I don't know that database at all. It looks, though, as if there were 3356 watches starting with 558xxxx in the database and this is the result for only one of them. As for diameter, je ne sais...... - it can't be the one for the watch, not even in mm.

    The database only represents observatory tested chronometers (competition pieces) and does not contain regular/series-production chronometers like your 40T.

    Answer from the database observatory that’s explains it ! Thank you Hartmut !
