Many of you Invicta fans will recognize this pic as a mechanical (manual wind) Invicta skeleton watch. After a long wait for delivery, I finally received mine yesterday.

I haven't owned a manual wind watch in many, many years and am somewhat nervous about the possibility of over-winding this one and breaking the mainspring.

As I *think* I recall reading somewhere, about 40 daily turns (20 full turns ?) will suffice.

How can I know for certain when I've wound it enough? Is there any safeguard in this watch to prevent over-winding?

I have one manual wind Invicta. I turn it about 15-16 times (Idon't know if these are "full" turns or actually more than a full turn each) At this point I feel resistance and stop turning. I don't wear the watch every day so I don't know how long it runs before winding down.

On that watch, (which is nice by the way), you should be able to see the main spring. When it gets tight, small, and compact it is wound fully. If it is spread out and you can see in between the layers of spring, it needs winding.

Many auto's now have a clutch that prevents overwinding, although I'm not sure of manual wind's offer this or not... if it were me, I'd look at the mainspring and see if there is slack. Or if you intend to wear/wind daily, 15-20 winds should be sufficient.
