Just like how I tested the power reserve of the AP 15400, I also wanted to test the power reserve of the PAM 508 to see how it compares with the original.

Similar to how I tested the AP, I tested the Panerai in a similar manner:

The Test

To accurately test the power reserve of the PAM508, I wanted to make sure that it has a full power reserve before setting it down.

I wasn’t as active as I was previously when making this video as I was when doing the test for the AP. But to compensate for this, I wound the watch more than 30 times to ensure that the watch was on a full power reserve.

After winding the watch and shaking it around a lot, I laid the watch down at a flat table at 5:28PM on the 9th.

I then made sure to check up on the watch without moving it to ensure it was still working especially at crucial times such as before 12 o clock, before the date changes, and before noon and after noon.

The watch finally ran out of power at 2:05AM on the 11th.

So doing the math on that, that is a total of 32 hours and 37 minutes.

Set the watch down at 5:28pm on the 9th.

Total Power Reserve of 32 hours and 37 minutes

How does it stack up

A power reserve of 32 hours and 37 minutes it is significantly less than the power reserve of the AP which is disappointing since the original PAM 508 has a higher power reserve.

A power reserve of 32 hours means you can only leave this watch off your wrist for one day before it starts stopping on you by the second day. This is fine for me because I wear this watch as my daily beater, but that is something for you to take into consideration.

The authentic Panerai PAM508 has a power reserve of 3 days (72 hours) which means that this watch has a power reserve of about half the original.

Authentic Panerai PAM508 has a power reserve of 72 hours so this is about half of the original

That is kind of a let down since I was expecting higher.
