Deciding what to restore and what to leave untouched is always difficult when you have a vintage piece that needs some work. If the case is only slightly worn or tarnished, most collectors would rather leave it alone. Likewise with the dial and hands. I don't see any value, however, in leaving a movement in worn condition if it can be restored by the manufacture with original parts (including replacement parts, if needed).
My main reason for having the watch serviced was the condition of the movement. It was running, but the rotor was loose and the amplitude was low - both indications that it needed an overhaul. Because the case was more than a little worn, I approved the light polishing that is included in the cost of service. I also approved the replacement of the crystal, which was an added cost. The wear on the dial, while visible, was consistent with the age of the watch and, in my opinion, added to the authenticity of its vintage. While I am certain that VC would have done a beautiful job on the dial, I declined to have it refinished at an additional charge. Likewise, I declined to have new hands put on the piece. They are still in good shape and there is always the danger that they will not be exactly the same as the original hands.
Looking foward to chatting more next time I see you.
