A lot of rumours are flying around since a couple of days on this topic. A pretty reliable source is @patekaholic on IG who took a list on his IG story which has mentioned 5168G, 5968A, 5235G and some more as running out models.
My dealer has confirmed on the three aforementioned references and has named some more like 5296, 5396 and 5320.
The biggest surprise for me was the 5968A which had been introduced only last year. What do you guys think? Will there be a 5968 in a precious metal like G or R at Basel 2019?
