Power Reserve Test!!!!!!

[sushisummo]

Hi all,

I recently saw a thread on power reserve on Rolex should be about 40-48 hours on fully wound from a dead stop. I did my own test (wounding it 45 times) and here's the results below:

1) TT GMT IIc (V series) only 37:35 hours

2) TT Datejust (M series) only 38:35 hours

3) SS Yacht Master (M series) only 38:35 hours

All three watches did not reach the 40 hours mark. Is that Normal?

Just wondering.

Thanks all.........
