I have seen the message only now
By calatrava do you mean the "96 like" (which is "my" meaning) or all three hands Patek (which is then a ton of references, impossible to get all of o them)
By 96 like I think of that case shape and a flat bezel with no step ( if you had a step or a non flat bezel, you can add 10 references or more...)
Not 100% sure about calibers and diameters, if someone see a correction to make please share.
96 in 30.5mm, multiple calibers and dials possible snap on caseback
570 in 36mm , multiple calibers and dials possible snap on caseback
2457 30.5mm 27SC caliber snap on caseback
2545 31.5mm with the 12-400
2555 31.5mm with 27sc similar to 2457 but with screw down caseback.
3438 31.5mm with 27-460 caliber
3796 31mm 215 PS with the typical dial and dauphine hands
5196 37mm with 215 PS with the typical dial and dauphine hands
There is also the small 438 in 28mm with 10-110 caliber .
