L.U.C XPS Twist QF

Original: The crown has multiple positions that independently advance calendar displays. Pulling to different crown positions should engage different calendar functions with clear detents between positions.

• Crown with only one or two distinct pull positions on a stated three-position QF watch
• Calendar quick-set that advances multiple displays simultaneously from a single crown position
• Crown that rotates continuously without engaging a calendar function in the quick-set position

Original: Same annual calendar principle as the 1966 Annual Calendar: automatic correction at month-end except February. The QF mechanism allows quick correction rather than requiring waiting for the automatic advance.

• Calendar that requires correction at months other than February
• Calendar display that advances in multiple jumps at month-end midnight rather than a single jump

Original: The XPS Twist QF maintains an exceptionally thin case despite the annual calendar. A watch claiming to be an XPS Twist QF with a case visually thicker than the time-only XPS is presenting incorrect specifications.

• Case height noticeably greater than the XPS family profile, inconsistent with the claimed ultra-thin construction
• Movement through caseback showing a full-size rotor rather than the micro-rotor

• Exhibition caseback displaying Cal. 96.01-L (or appropriate QF variant)
• Micro-rotor signed "L.U.C." visible through caseback
• Geneva Seal mark on the movement
• Reference 161976-9001 on the case band
• "Chopard" and "L.U.C" on the movement plate
