Few questions about Time Bomb II

I had a couple of other automatic watches before. The first one takes thousand of arm swings to fully charge and reserve energy will power the watch for about a few days. The last one I had takes about 250 swings to have a day of reserve energy and full reserve will power the watch for 4 - 6 months. And those watches had a button to check how much reserve energy left.

So, how many arm swings will fully charge the TB II? And how can you tell how much reserve energy does it have left energy left in the mainspring? I tried to read the manual but didn't find those info in there.

Thanks.

'power reserve' in an automatically wound mechanical watch is just a loose term for how much energy is in the mainspring.

you cannot tell how much 'reserve' is left apart from noting the time at which it is exhausted of it's energy and stops.

if you fully wind it by the crown (25-30 turns as stated above) you can then measure exactly how long before it stops without being worn.

Ok, I updated my question in the first post.
