My observation - in general - is that the watch buying population is becoming more and more polarised between Sports and Dress watches.
With casual dressing and now Covid working from home arrangements, the role of dress watches perhaps, may be taking a back seat. Furthermore, Independent watchmakers are coming up with incredible timepieces- think Rexhapi/Voutilainen/Journe/Gauthier/Gronefeld. That might explain the competition for Patek, Lange, VC, etc.
Like you, I love the 5320G and that will stay with me!
