THIS IS AMAZING, not really news but so cool:

Question about accuracy of 3120 movement
Please accept my apology if this question has been asked before.I had my 15400 for about a week now. I noticed that it is gaining about +2.5 ~ +3 seconds per day. I would comfortably say that it keeps very accurate time even when compared with my Rolex which is COSC certified.However, for the same movement that is housed inside my Diver, it keeps on gaining over +12 seconds per day, though the official AP website stated that this is an acceptable standard up to +15s.Both 15400 & Diver is not my daily beater and I will keep it on my winder when not worn. Both were set to turn in bi-direction with 650 TPD, so the basic winding environment is same to both.I just wonder why the same movement will perform very differently in different model. Is it due to the design and configuration is very different.Any fellow AP owners have experienced this same situation and can help to share some clues.I'm puzzled, please help. Thanks.

GMT 16710 bezel change
Hi all. Quick one please. I have just swapped the Pepsi bezel over to a new black one I purchased. What is the metal ring under the bezel that came off when changing please? And do I need to put it back? All of the videos I have watched don't seem to show this ring. Thanks in advance. Sent from my iPhone using Tapatalk
