Pretty good reserve power, I'd say.

[watch watcher]

So, a few days ago, I decided to wear my DJ, putting it into rotation, so-to-speak. It was dead from sitting, so I wound it 3 or 4 revolutions to get it going (not the recommended 40), then slapped it on my wrist. When I got home from work 8 hours later, I took it off and out of rotation. I didn't move it. Eventually, it stopped after 49 hours. Not bad for a lazy winding amount and 8 hours of wrist movements.

Maybe that's not remarkable, but I thought it was.

Question, though: Are cumulative wrist movements enough to fully "charge" the watch? In other words, had I wound it 40 times (or more), do you think the duration of operation would have been more that 49 hours?

Doubt it, the PR on my Sub-C's mvt., the 3135 is rated around 48-50 hours, I'd guess yours is similar, the mainspring of a movement can't go beyond a certain point, if it does the clutch mechanism lets it slip so it doesn't break. So you can't really get beyond the rated PR no matter what you do to the watch.

I've been pleasantly surprised at how my Sub stays near full wind from only moderate activity, and I don't wind it, just wear it about 15 hours a day.
