My judgment is based on the following information:
1、what is the difference between those ref.4838&ref.4907? ref.4838 ,sub seconds,with Cal. 1007/BS .ref.4907 ,center seconds,with Cal. 1008/BS. the case diam of two ref. are all 35mm.
2、the ref.4724, with Cal. 454(CR with cal.1007/BS&cal.1008/BS),37mm(CR should be 35mm).
3、the watch with the Cloisonné dial is 35mm,with cal.454,correctly should be ref. 4907.(maybe the caseback didnot carved chronometre royal?)
vintage VC with similar case,maybe different ref.
because of different diam. such as ref.6068 vs ref.6110
