Sized at 45.6mm by 27.4mm, this JLC Reverso replica carries the Master Reverso Tribute Monoface Small Seconds designation, reference Q3978430, and a clone Cal. 822/2 inside a case that sits noticeably larger than the standard Reverso dimensions. The green dial is the defining visual element here, a color that entered the Reverso catalog relatively recently compared to the traditional white, black, and silver options. At 45.6mm in length the case sits at the larger end of the Reverso range, where most men’s references stay under 43mm. Jaeger-LeCoultre positioned this size bracket for collectors who want the Reverso shape without the compact proportions that some find too small on larger wrists.

Technical Overview

• Case dimensions: 45.6mm x 27.4mm (length x width)
• Movement: clone Cal. 822/2, manual-wind, 21,600 vph
• Dial color: green with applied indices
• Case material: stainless steel
• Crystal: sapphire
• Functions: hours, minutes, small seconds
• Strap: leather with folding clasp

The 27.4mm width adds visual mass that balances the 45.6mm length. Narrower Reverso cases at this height can appear stretched, but the wider proportions here keep the shape closer to the classic ratio.

Inside the Movement

The clone Cal. 822/2 drives a three-hand layout with small seconds at 6 o’clock, manual-wind at 21,600 vph, with a 42-hour power reserve where the genuine Cal. 822/2 holds 42 hours. That is the monoface caliber: Duoface references run the 854A/2, which drives a second dial on the reverse panel this version does not have. Green dials have gained traction across multiple brands since 2020, but in the Reverso context the color reads differently than it does on a round sports watch. The rectangular frame constrains the green surface into a vertical panel rather than a circular field, which changes how the shade shifts under varying light. For a completely different color temperature in the same 45.6mm format, the women’s reversible white dial version works as a direct contrast piece. Both belong to the wider Reverso catalog, which spans every size from 20mm-wide ladies’ models to these oversized Tribute references.

What Sets It Apart

The green dial at 45.6mm occupies a specific intersection that no other current Reverso model shares. Smaller green Reverso references exist, and larger Reverso cases exist, but this particular combination of color and size targets buyers who want maximum wrist presence from an Art Deco case shape. This JLC Reverso super clone delivers that statement without departing from the core Reverso identity.
Green came late to this case shape, and the white, black and silvered dials it has to win against are all gathered under Reverso super clones. Whether the oversized Tribute is the reference to start with is answered in how the Reverso ranks inside JLC.
