Why Sell Your Franck Muller to GoldTrust?
Franck Muller occupies a specific corner of the high-end Swiss watch market: distinctive curved tonneau cases, a taste for complication (tourbillon, perpetual calendar, minute repeater), and collectable limited editions in precious metals. Valuing one properly requires reading the reference, the movement, and the case material, and pricing against the current haute horlogerie secondary market.
At GoldTrust we identify the reference, inspect the movement and complications, weigh precious metal cases, and build the offer in front of you. Every step is explained. If the offer does not work, the watch stays with you, no fee. If it does, payment via instant EFT lands during the visit.
GoldTrust is a licensed second-hand goods dealer, registered high-value goods dealer, accountable institution, and Jewellery Council of South Africa member.

What Affects Your Franck Muller’s Value
- Collection and reference. Cintrée Curvex is core; Aeternitas and grand complications sit at the top of the range; Vanguard is accessible contemporary.
- Complication. Tourbillon, perpetual calendar, minute repeater, and multi-axis tourbillon references support significantly stronger offers than time-only pieces.
- Case material. Steel, titanium, rose gold, white gold, yellow gold, and platinum. Precious metal cases add intrinsic value.
- Gem-setting. Diamond-set bezels, cases, and bracelets add stone value on top of watch value.
- Condition. Case geometry, dial originality, movement health, and complication functionality. Do not polish precious metal cases.
- Limited edition and numbered status. Franck Muller produces many limited editions; documented numbering and provenance support stronger offers.
- Full set. Box, warranty certificate, booklets, and original purchase invoice.
Box, Papers, and Service History
A full set Franck Muller includes the watch, presentation box, outer box, certificate of authenticity, warranty card, booklets, and purchase invoice if available. On complications and precious metal pieces, full set adds meaningfully to the offer.
Watch-only is still sellable. The offer is lower, particularly on high-complication pieces where provenance and documentation really matter. Bring any paperwork you have, even partial.
Service records from Franck Muller or authorised service centres add confidence, particularly on tourbillon and high-complication references.
Preparing Your Franck Muller for Valuation
- Do not polish the case. Particularly critical on precious metal and gem-set pieces.
- Do not attempt to adjust complications. Tourbillons, minute repeaters, and perpetual calendars have specific setting procedures and can be damaged by improper handling. Leave complications alone.
- Bring the full set if you have it. Box, certificate, warranty card, booklets.
- Note any service or repair history.
- Bring ID. Valid SA ID or passport for FIC compliance.
- Book an appointment at one of our offices across Gauteng, including Sandton, Pretoria, Centurion, Boksburg, Cresta, and Bedfordview. We also serve Umhlanga, Cape Town, and George . Home visits available in many areas by arrangement.
Inspection, reference identification, complication verification, offer, and payment all happen in one appointment.
