ZF Aquanaut 5164A arrived today so took around a month from payment confirm.
I wasn't sure what to expect when I ordered this, but I'm happy to say it looked much better than the pictures. The dial and cash are finished very well. Not sure if it is exactly the same as the gen but looks like a Patek quality dial to me
The date function uses the pusher on the right side. The local day night indicator works well. See through case back to the movement is great. Movement is much cleaner than the QC pics. Really sparkles.
GMT buttons and hand and home day/night indicator are not functional. The GMT hand pretty much just does what ever it wants. Sometimes its 5 hours away from the hour hand, other times its 8 hours away. In an odd way, its charming, but some could find it annoying/distracting. However, it really doesn't impact the watch in a meaningful way. Lume is very bright and evenly applied to the hour markers and hands. Lume is weak on the date hand, but that is to be expected as it is so thin.
Clasp has great finishing and the strap is very comfortable and feels similar to an Apple watch solo loop.
Size of the lug to lug is great for my 16.5cm wrist.
Thanks to the puretime team for a good product.
