Having put it on around 06:30 hrs yesterday morning and worn it through to 20:00hrs this evening, bar overnight in bed, I reckon it should be fully charged.

. . . . . .

Now, into Phase 2, to run it down and establish the Power Reserve.

By my reckoning 56 hours will take me through to 04:00 hrs on Sunday morning. We'll see and here goes.

Nearly made it. :) :)

The watch initially stopped at 23:30hrs Saturday night i.e. after 51.5 hrs.

A useful feature of doing this test is the watch being a GMT, as one can tell for how the GMT hand has been set whether it is showing am or pm.

Having picked it up, looked at it, then put it down again it started running again; this is without any discernable attempt to wind it. I have an unproven theory that with any watch it will stop when it meets a point of resistance, somewhere in the movement. By picking it up, looking at it and then putting it down, it will 'bump' the movement into action until the next time that it meets a point of resistance, and then stop.

Thus happened with the watch showing 02:00hrs Sunday morning i. e. after 54 hrs.

I've picked it up, looked at it and put it down again and its has, again, started running (and still is). We might yet get to 56 hrs! :wink: :wink:

Final update to follow tomorrow.

Greetings from Spain, fellow inmates! I do appreciate all the efforts testing the SW330-2 for the power reserve. It seems those that have been tested in this thread have not achieved the 56 hours stated, and it appears stated observations are closer to 50 hours or so. Having learned this, I am unlikely to return my C63 GMT for inspection and repair since it seems my watch is consistent with others regarding the PR, and perhaps the new movement doesn’t quite live up to its billing due to initial production kinks. I’ll most likely inform CW customer service of our findings here and possibly Mike France.

Thanks again to all and cheers from Barcelona.

I tend to have 3 watches set and running at any given time. These will be the main watches that I wear during a week, maybe longer. Yes I may pick up another watch in that period and wear it for a day, before letting it run down, as I know I won’t pick it up again for another month or so.

It’s easy enough to keep three set and running, if they have a decent power reserve. I think I have probably worn seven watches over the past couple of weeks. The three main ones have PR of 58, 60 and 72 hours. Easy enough to pick up, put down as I wish, without any stopping and whilst keeping a good level of accuracy (I don’t use watch winders). The three are all still running and when I checked this morning the timing ranged from +1s-+8s cumulative over the past weeks.

This is interesting. I can conceptually understand what you are talking about here but I can't relate. Not once in the 40 or so years I have worn watches have I passed on wearing a certain watch because it was stopped. Not once. Well, that isn't exactly true, I have not taken my Apple watch on a few runs because it was dead but I'm not sure that counts in this context :lol: .
