GMT II batgirl power reserve expectations?

[salmanhamid]

Hi all

I recently bought a Rolex GMT-Master II 126710BLNR, from a AD, not sure if I am getting the power reserve as close as advertised 72 hours.

A fully winded watch in the morning, wears it whole day, takes it off at night gives me full 24 hours plus another 12 on top max before it stops.

Say, on Thursday morning I wind the watch takes it off before going to bed, watch generally stops by Saturday morning, is that normal or shall I be concerned?

Thanks in advance.

Sal
