How it differs from other seven-day Curvex references
Franck Muller Japan’s official catalogue places references 8880BS6PREMA, 8880BS6SQTD and 7042S6SQT in its “7DAYS POWER RESERVE” section. The pictured models have different case materials and dial configurations, so a shared reserve category does not make them interchangeable with 8880BS6PRVINACW. Consult the Japan catalogue.
Another distinct model is the Grand Cintrée Curvex 7Days Power Reserve, reference CX36S6PRFOJ ACACBUBR. Franck Muller Japan lists its case as 36.00 × 53.10 mm and displays a price of ¥3,245,000 including tax. Those are details for that Japanese Grand reference only—not specifications or a price estimate for 8880BS6PRVINACW. See the Grand model listing.

What to check when comparing a listing
Search by the full reference—Franck Muller 8880BS6PRVINACW—rather than by “Vintage Curvex 7-Days” alone. Before treating two listings as the same watch, compare:
- Full reference number, case material and dimensions.
- Dial configuration, including whether it is a standard or skeleton design.
- Movement and winding type, plus the stated reserve.
- Included strap and buckle; confirm attachment measurements before assuming a replacement strap will fit.
- Condition, service history, papers and seller provenance.
- The asking price and availability of the exact variant from a verifiable seller.
The official product pages establish specifications, but not the current availability, market value, production year or condition of a particular watch. Verify those points against the exact listing and its documentation.
