The Pam 561 is a Luminor, hence a Base ( without seconds ) which, with its white dial, is well known from the old school guys, as we used to see the Pam 10, in the early 2000's which came with the same dial, and the same case.
But here, the difference is that Panerai housed an 8 days movement, instead of the ETA.
The Pam 561.
Note that there is another white Luminor Marina Panerai housing the same Cal 5000, but with a small second located at 9 o'clock, whose reference is Pam 563, for your information, which is the " daughter " of the Pam 3 and the grand daughter of the Pre Vendôme Daylight Slytech.
Quite a fresh offer, and original, too.
Same story for the Pam 564: The combination of a titanium case and a brow dial is not new, as it was first used on the legendary Pam 36 " Marina Militare ", with tritium indexes, before we saw others coming with luminova indexes. The combination is very appealing, I find.
The same watch comes with a Base dial, with the reference Pam 562.
The Pam 564:
While the Pam 561 has a stainless steel case, Panerai chose titanium for the Pam 564. Both references are 44 mm big.
And both are 300 meters water resistant, despite their sapphire case back.
A word on the movement, which is the P 5000. It is a hand wound movement with a 8 Days power reserven which I find very astute and quite exclusive on a diving Watch, 35, 7 mm big, 4, 5 mm high ( only ), with a variable inertia balance, and beating at 21 600 alternances per hour.
Here a view on the movement, through the sapphire case back:
Not bad, not bad at all....
Looking forward to reading your thoughts and reactions,
Best.
