96 hours?
I think the 5140, which is where I remember the 502.3, has a normal (46-48) hour power reserve. It's based on a F.Piguet caliber, but one that only Breguet uses these days. It's distinctive from the back, the rotor is about 90% the diameter of the caliber and off-set from the center

What calibers is it based on?
The 502.3 SD with a 96 hour reserve - what is the base movement... a Lemania or a Piguet? Does Breguet use multiple barrels to achieve such a long reserve? Thanks.

yes, 96.
Every website says the 5930BB has an automatic with a 96 hour power reserve.
Ahh, different caliber
According to a 2004 Catalogue, that reference has a 517/1 caliber movement www.breguet.com Assuming that it is just a tweek of the 517GG tha powers the marine, it is a piguet 1150 with some slight mods: www.network54.com A
