short for the 'available'. Prices in the secondary market as a spot price merely reflect an individuals propensity to queue (or jump the queue).
I never have figured out the prices for the following:
1. MJLC Rose Gold Reverso series. Iconic case, finishing was good, all original designed and manfactured movements and cases. A common theme to the series and some horological innovations as well (think of the repeater and the chrono). I just do not get it. Compared to present offerings from the same company, this series (to me) represents the best horological bargains on the market today. Why are they not sought after? Who knows - my guess is that they are not /were not limited enough, perhaps too discrete and unassuming in presentation, no marketing connected with it.
2. Some FPJournes - particularly the Resonnance have at times gone for less than I thought they would. Perhaps too idiosyncratic in design?
3. AP RO OS Alinghi, RO Perpetual are also a ponder on why.
4. Roger Dubuis does not seem to do so well in the secondary market as well.
As to why others have prices spiralling upwards? I can only surmise that there is too much money chasing particular models (for whatever reason). Partially due to particular models having cache, but outside of that, it would be fun to think of a way of finding out beyond individual speculation and introspection.
