In addition, some old models of 116523 do not have laser inner ring marks, and later 116523 also have laser internal ring marks. And 116503 has it all. Bell and ross replica.
Open the cover to see that the movement is also the 4130 movement. The old 523 has the old white and blue niobium hairspring. The new 503 only has a blue niobium hairspring.
