Zusammenfassung:	Timepiece gear train device (1) of reduced height with a large power reserve, driving display means (4) including a cannon-pinion (5) and an hour wheel (6), which are driven about a main pivot axis (AP), secant to a barrel (3), by a motion work (7) and including a driving wheel (8), which pivots about a secondary pivot axis (AS) external to said barrel (3) and is friction coupled to said motion work (7) on a friction surface (9) coaxial to said secondary pivot axis (AS). Said driving wheel (8) includes a driving cannon pinion (83) pivoting about a wheel body (80) along said secondary pivot axis (AS) and coupled by a friction spring (84) to a shoulder (85) of said wheel body (80) forming said friction surface (9), said driving cannon-pinion (83) cooperating with a minute wheel (14) pivoting about a minute axis (AM).
