Many similarities, but also many differences. Manual wind chrono. 41mm v 42mm. Platinum. Both beautiful. But I would say cousins rather than brothers.
I didn't have much opportunity to take pictures of the two together. Both now sharing the same safebox for the next few months to get to know each other!
I have owned the 5070P since 2009. It has been a mainstay of my collection. To be clear, it is one of my favourite Patek Philippe and even one of my overall favourite watches. Teh decision to add the 5370P was not hard, but I was very curious how the two watches would feel side-by-side.
I have worn the 5370P now for the last two weeks so it will soon be time to give it an on-the-wrist review.
For now, a side-by-side shot with the 5070P. A first...I believe?
