through the crystal back of the 5070s. as i recall the ref 2512 made in the 1950s had a huge case with a nouvelle lemania movement and is considered very much by avid collectors. i personally do not like huge cases but i will make exceptions for the 5070s in platinum and white gold.
on your thoughts on 5960 - prices have not fallen as of yet due to a high demand, although it is to be said that the movement is a beginning of a new epoc and will be utilised for other complications. that said, it is not absolutely clear if the production of the 5960 will run indefinitely. i personally think not.
