In Patek's offerings there is very little new. If 5170 is now made of WG and the indexes are replaced with Breguet numbers, it can not be called "new".
A new reference is 5200G. However, I can just see the basic idea of 5100 downgraded with day and date and added with a less complex case. Is it really new?
I am quite patient with Patek this year. I understand that next year there will real fireworks. It's lovely not to be forced to acquire anything new this year.
Best, Kari
