Yeah, not sure what they mean by Cal 36 LS either, unless it's the Cal 36
0 LS production version, i.e. the Basel watch from 2006:

I thought the V4 would have been ahead of the 360 LS in the queue for production, but you never know.
That pricing would make it cheaper than the Carrera 360s too, though I only remember having seen those priced with the precious metal cases - the steel case may well have worked out cheaper than that Monaco.
