Hi Chris,
... the bridge side pivots of the minute counter, chrono runner are jewelled as well (making 17 jewels total) and as I understand in that version the chrono coupling wheel has one jewelled pivot on the top pivot/clutch.
The dial side of fourth wheel (that's the one carrying the seconds hand at 9 ) is of course jewelled - the center wheel isn't jewelled (as the 15 jewels for basic going train indicates).

is the arbor for the small constant running seconds hand at 9 o'clock jeweled? Are any parts of the chronograph gear train jeweled? I suspect not as I think 18 jewels is roughly the requirement for a fully-jeweled 3 hand watch? Thanks!
