7750 movement power reserve

[superduper]

I got a Pam with 7750 movement. Wanted to know what's the average power reserve I should be getting. I get about 24hrs on a full wind. Should it be more than that? I know a service will help but what is the general consensus?

Usually, at the beginning they have about 30-35 hrs, but this is not a fix rule, as reps they have many variations

I your watch maintain 20-24hrs that will be enough for a normal use.
It just should not stop during a long night to be useful

Get the service when you have a real problem

i get over 40hrs easy on my 7750s. Anything less i think needs a service. I've got over 20 watches with 7750s in it

I replaced the mainspring on my 364 and 382 (both A7750 sec@9) with ETA ones and I get about 58hrs power reserve.

I get 49-50 hours on average with my PAM346
