This looks like to be a ref 2077 screw back chrono which is a sought after piece.
But I am very much confident that the watch did not leave the factory with this dial.
Firstly there are no hour marks - this kind of dial was used on watches with bezels which have the numbers engraved like the officers chrono - compare the replica!
Secondly the space from the outer scale to the rim is much too wide.
just my 2 cents
