Explorer II 216570 power reserve question

[Thx67]

Had my explorer for a few weeks now and loving it. However I’ve noticed that the power reserve isn’t great. I admit I’ve been a bit lazy over the festive period but I’m used to wearing my watches and leaving them off the wrist for a couple of days. With the Explorer it’s been dead when I pick it up lasting possibly 44-45 hours. It’s only on casual observation at this point. Nearly all my other watches seem to get going after say 20 winds and last 2 days. Am I right in saying the Rolex needs more of a kick start to get to max power reserve to allow the PR to get fully charged by the rotor? In general I’m fairly active but I do have lazy days! I also stumbled across a bark and jack video that auto played after another video and in this he mentioned that the rotor can only charge a power reserve by around 20% (depending on activity of course) which would tie in with my early observations. Would appreciate any thoughts from the experts around here. This is NOT a complaint, it just seems this movement behaves slightly different to my omegas and tudors. Thanks in advance.

Most today will never fully wind there watches mainspring by just wearing yes they will keep ticking but full power -reserve doubtful.To test power-reserve manual wind it at least 40 plus full crown turns clockwise only.After a full manual wind it should run between 39-48 hours off wrist give or take a hour or so either way.

It takes more than 650 turns of the rotor daily, just to keep the movement running at the same level of PR.

If it is not fully wound when you put it down, it will not sit there ticking for two full days.

Every mechanical watch has it's own little idiosyncrasies.

Thanks very much for the replies. Kind of what I was hoping for. It’s super accurate but I guess I just need to top it up with a wind if it’s off for the weekend. I’ve been spoilt by the Pelagos PR I suspect. I never thought I would bother much about 70 hours or even notice it but it’s great to be able to put it on the table on Friday lunchtime and pick it up Monday morning.
