So, conventional wisdom (or is that WISdom) that I've always heard is that, for a modern manual watch, if you aren't wearing it all the time, you can let it run down, then just wind it when you want to wear it (assuming it's not months/years between use). Supposedly, modern lubricants are sufficiently good that there's no worry about pooling or drying out from non-use, at least not for reasonably short lengths of time.

But in the manual for my Vacheron, which has a modern movement (Cal. 4400), there is this:

"If your watch is not worn regularly, it is advisable to wind it daily so as to keep it running permanently and thus avoid the need for over-frequent adjustments."

Any experts out there want to comment?
