The Reverso Tribute Duoface Small Seconds (ref. Q3988482) is the dual-time Reverso, flip the case to read a second timezone with subsidiary seconds. 47×28.3mm steel or pink-gold case, the in-house caliber 854A/2 (hand-wind), and the slightly larger proportions of the Tribute sub-line versus the Classic. It is the Reverso that does the most without breaking the watch's design discipline.
The original 1931 Reverso protected the dial during polo by rotating into the case carrier. Decades later, watchmakers asked whether the previously-empty back of the case could hold a second dial, and the Duoface was born (the first Reverso Duoface launched 1994). The current Tribute Duoface generation arrived in 2016 with refined case proportions, a hand-wind 854A/2 caliber (one of JLC's most-finished modern dress movements), and dial variants in silver, blue, black, and brown.
Steel and pink-gold cases are standard.
Common things to check: case-back personalization (Reversos are commonly engraved as gifts, the back-of-the-case engraving conflicts with the second dial on a Duoface, so heavily-engraved examples are uncommon; verify any engraving against factory hallmarks); both dials' originality (refinished dials lose the crisp printing and applied-indices definition); case-rotation mechanism (the slide-and-rotate action should be smooth, any grinding or hesitation is a service flag, and on a Duoface this matters more because the rotation aligns the second dial); the second timezone is set via the case-back crown, verify both crowns function independently; strap (JLC's signature alligator with branded buckle).
