Vacheron Constantin

Well, what about this beautiful 4660 with p454/58 caliber? I did never see one before, any of you did? It's 36mm, yellow gold. ...  

The lug shape on that piece is pretty rare. Congrats on an excellent find! Tony

...the balance wheel looks huge. 36-38mm is perfect size for a dress watch for me with 7” and a bit wrist.
