The next watches I want to highlight are the Panerai PAM422 & PAM423 - both are 47mm Luminor Marina 1950's housing the in-house manual wind P.300X movement.  And once again, a quick cheat sheet for the P.300X movements:

P.3000 - no power reserve
P.3001 - power reserve on back
P.3002 - power reserve on front

Below is a picture of the PAM422 47mm Luminor Marina 1950 3 Days.  It's the same watch as last year's PAM372 but now with a sub-seconds at 9 o'clock.  Retail on the PAM422 is currently at $11,200.

The PAM422 is a beautiful classic Panerai IMO.  If you are looking to get a PAM372 and unable to obtain one, then definitely take a look at the PAM422.  It has the same gold hands and vintage ecru luminova found on the PAM372 but now with the added benefits of a seconds hand and a power reserve display on the back of the watch (see below picture).

The addition of the power reserve display on the back definitely makes the P.3001 movement look far more interesting than the plain P.3000 movement w/ no power reserve display.  As a result, the 2 huge plates on the P.3001 movement don't look as barren anymore and this simple addition of a power reserve display turns the P.3001 into a visually pleasing movement, at least for me that is.  The power reserve's gold hand compliments the gold wheels and balance wheel and gives a nice visual addition of color.

In the above picture, take a notice of the shape of the seconds hand at 9 o'clock.  It appears the luminova tip of the seconds hand is slightly elongated and thinner than the usual seconds hand found on the original Historic Luminors.  Nothing biggie but just a small observation. 

And below is a video of the PAM422 from all views.  Pretty ain't it?

Now let's look at the PAM422 47mm Luminor Marina 1950 3 Days Power Reserve which has a retail price of $11,300, $100 more than the above PAM422.  It's essentially the same watch as the PAM422, but the power reserve got moved from the back to the front, so the power reserve display is dial-side now.

I've never been a fan of whoever designed these Panerai's with the power reserve off centered at the 4:30 position.  The location of the power reserve isn't symmetrical to my eyes and gives the watch an uneven look.  Some people like this design so to each his own

There's not much else to add, so I will leave it here with a video of the PAM423 below:
