If we are to create a hierarchy between the compressor / supercompressor watches, I would then rank:
- 1st, the anteriority.
Regardless of the manufacture / non manufacture aspect, I think that from a collectors point of view it is good to know which are the brands / models that have used the Piquerez SC case first ( --> I don't have the answer from the top of my head, nor do I know if the information is known, but I believe this is the first criteria to consider)
- 2nd, the 'manufacture' factor
Of course, when many different brands have been using the same (or similar) watch case / construction (twin crown / internal bezel), then if we want to discriminate them, the 'in-house' movement factor becomes important.
So then, I would rank equally, Enicar, Bulova, Longines, Universal Geneve, IWC, Jaeger LeCoultre and to some extent LIP (in-house electric), as all these brands did equip the EPSA cases with their their own in-house movements. Jaeger LeCoultre (Polaris), and Vulcain (Cricket Nautical) of course stand out as they have an extra complication (and an extra crown)
All the others would come next according to this criteria (and there are many other examples, using AS or ETA movements). But then, the XL cae (42mm), and the thin profile would be more attractive than the smaller (36mm case), or the thick profile...
So as always it is not simple.
Especially when you take dial design into account. Some with in-house movements / thick profile can look less desirable than some with ebauches / thin profile.
A collector's life is never simple..........
