First,the crown is not original, the dial is not in good condition, and the movement is lack of part . So its not a good purchase object.
Second, the shape of the case reminds me of Chrometre Royal, ref 4907 & 4838. Of course, it doesn't use 1008 / BS. The case size is close to 35mm, with calibre 454/5B. It's not another model, 4724(jumbo).
The letters and numbers on caseback looks ok, this is the first time I see the ref 6000. If any friend seen this model before, could you provide more information?I would be very grateful.
Third, when I carefully observe the connection between the lugs and the case, I feel that there are very rough welding marks. The watch's lugs seems to be after-made.
I've seen V&C use this shape case before, and the manufacturer is poin ç on de Ma î tre : Key of Geneva 5.Croisier, Georges, succ. de Lacreuze et Cie. But the case of this watch is made by 23. Eggly & CIE. What do you think about this watch? Is there exist a model 6000? Please state your opinion.
