RICH Factory (RF) produces the highest-tier replica of the Cartier Santos Skeleton in the 39.8mm large size (WHSA series), powered by a dedicated super-clone of the manual-wind Calibre 9611 MC with two visible mainspring barrels and Roman-numeral skeleton bridges. Four variants are available: steel, black ADLC, gunmetal and rose gold. Community reviews on RWI and r/RepTime consistently rank it as the best skeleton Santos replica currently made.
The defining feature of this watch is the movement. RICH Factory built a dedicated super-clone of Cartier's in-house Calibre 9611 MC — not a generic movement hidden under a skeleton dial. Key specs: manual-wind, 28,800 vph (4 Hz), 20 jewels, two functional mainspring barrels visible through the dial, and skeletonized bridges shaped as Roman numerals with the correct gear-train layout. The clone keeps time within roughly ±5 seconds per day in community timegrapher reports, and holds approximately 50+ hours of power reserve. The movement's architecture depth is what separates this replica from cheaper skeleton Santos options.
The case is 39.8mm — the large Santos size — with the same flat-to-wrist ergonomics as the genuine. The QuickSwitch strap system is fully functional, and the case accepts genuine Cartier bracelets and straps, so parts are interchangeable with authentic Cartier pieces. The screw detailing on the updated bracelet links sits flush, matching the genuine's finishing. Water resistance is rated for daily wear; we pressure-test crystal sealing on every unit before shipping (see QC checklist below).
| Variant | Case Finish | Price | Link |
|---|---|---|---|
| Steel | Brushed stainless steel | $748 | View |
| Black ADLC | Black ADLC-coated case | $768 | View |
| Gunmetal | Gunmetal grey case | $768 | View |
| Rose Gold | Rose gold PVD case | $838 | View |
All prices include free US shipping. Every watch ships with RICH Factory USA's 2-year after-sales warranty and QC photos before dispatch.
Pros: Exceptional movement architecture depth for the price; accurate Roman-numeral bridge shaping; correct gear train; flush screw detailing on updated bracelet links; genuine-compatible QuickSwitch system; the closest thing to the real Calibre 9611 MC you can buy at this price point.
Known flaws: The sword hands are painted/lacquered blue rather than thermally heat-blued — under direct sunlight they reflect less iridescence than the genuine. Some early production units had crystal seal issues (moisture inside the case); we now pressure-test every unit before shipping. As with every factory, QC varies slightly from batch to batch, which is why we photograph and inspect each individual watch before it ships — you approve your exact piece.
When you receive QC photos for the Santos Skeleton, check: (1) skeleton bridge alignment — the Roman numerals should be straight and evenly spaced; (2) screw flushness on the case and bracelet links; (3) the sword hands — both should be the same shade of blue; (4) the QuickSwitch mechanism releases cleanly; (5) crystal seal — no fogging or moisture marks. We check all five on every unit before shipping.
The movement and case are extremely close to genuine, and parts interchange with authentic Cartier straps. The painted hands are the most obvious tell under direct light. Most owners consider it "closest to gen" rather than strictly NWBIG — which is an honest and accurate way to describe it.
RICH's version has the deeper movement architecture (dual barrels, correct bridge layout) and better strap comfort. MLF's straps are notably sharper-edged. Community comparisons on RWI rate the RICH version higher.
Yes — the QuickSwitch system and lug geometry accept genuine Cartier bracelets and straps.
Approximately 50+ hours from the dual mainspring barrels.
