What is the mainstream of the branded replica watches? Petek started as a trend intended to appeal to the hardcore of collectors and somewhere along the way it became a key pillar in major brands release strategies. 2017 is a special year for novelty, new upgrades, and amazing improvement.
As far as the dial is concerned, most of the attention heaped upon the 5320G has paid much attention to it, and it's easy to find the reason. The layout is balanced, with day and month apertures at the top, also with a moon phase display and pointer date at the bottom. The functions at six are flanked by relatively discreet portholes displaying day/night and leap year indicators individually. Besides, the dial is very warm ivory or cream color, combined with applied black gold Arabic numerals and syringe-style hands. Both hands and numerals are full of Super-LumiNova, and the entire package is topped off with a Plexi-evoking glass box sapphire crystal. If you're looking for nits to pick, you could deny the fact that the pure white calendar discs are not harmonious with the dial or the fact that the dial is lacquer rather than enamel. However, all this doesn't take away from just how stunning the 5320G is on the wrist. 
As for me, the case is just the real matter, specifically the lugs. Triple-stepped and gently curving, this Deco design touch is perfection. Add to these lugs the broad bezel and middle as seen from the top down, and the slightly recessed crown, and there's no denying that Patek has successfully captured their history in this piece. 40mm is rather big for this style of watch, and I guess 38-39mm would have been enough size upgrade. Interestingly, the case is in fact a single piece of gold, something that surprised me after having held the watch in my hands - I would have thought it had a more sophisticated multipart construction.
The 5320G is powered by the caliber 324 S Q, the first time the base 324 has had an everlasting module popped on top. The power reserve isn't huge enough, at around 40-45 hours, but the finishing, as with all replica Patek Philippe, is superb and excellent.
Consequently, the 5320G is a wonderful example of Patek Philippe moving with the times. They've cherry-picked some of the sweetest elements from their enviable past and put it all into a stylish, delicious package.
