Aha! The concept of the ET....please read on.....

Andrew,  thanks for the interesting insights.  I never thought about it this way but now that you mention  it  using an auto winder for a manual wind watch or for that matter using a winder for  an automatic watch that is lacking a tourbillon is indeed in some ways very much like using an "external" toubillon [ET]!  If the purpose of the tourbillon was to negate the effects of gravity and/or to lubricate the parts better, then indeed the winder can accomplish that much more easily and cheaply although clearly not quite as elegantly.

As you know far better than myself, a tourbillon in a wrist watch that is being worn,  is really of little practical value and is more than anything else a way for the watchmakers to showcase their technical prowess.

So using the  input from  you and Nicolas,  I shall heretofore make the following change in the way I have been treating my watches at rest, ie, not on my wrist.  The automatics will stay on the ET.  The manual wind watches will, when not being worn, will be wound every 2 to 4 weeks and they will stay on the ET at all times.

Thanks and Best Regards to all !
