Help me check this vintage Vacheron Constantin

Hello, a retailer just offer me a new Vacheron Constantin, can anybody help me to identify it ? whether it is authentic or not ?? , Thanks you so much !!!    

This is the Detail of this watch

Ref# 7295 
Case# 423456 Mov# 595302

Some people say the dial was redone ( refinished) because the "Vancheron & Constantin" is quite blur and there are no "swiss" under 6 marker Can you give me some recommendations ?
