The Richard Mille RM07-03 BonBon is a 40 mm ceramic automatic watch with a black and golden skeleton dial and a rubber strap, from the RM 07 family that Richard Mille makes as its ladies' line. It is one of the colourful BonBon references, named after sweets and fruit, and the version in our catalogue is pre-owned. This guide covers the specifications we can confirm, what the BonBon line is, why Richard Mille uses ceramic, how the 40 mm watch compares with the 45 mm RM07-03 references in our catalogue, how it wears, dated prices from October 2026 and what to check before buying a pre-owned Richard Mille.

What is the BonBon line?
Richard Mille founded his brand in 2001 and built it on cases in unusual materials, skeletonised movements and a price point far above most luxury watch makers. The RM 07 family is its ladies' line, and the BonBon watches are the colourful, playful references in it, with names taken from sweets and fruit. Our catalogue lists RM07-03 references called Mars, Litchi and Myrtille, among others, and the 40 mm black and golden watch discussed here carries a darker palette than its names suggest.
Why does Richard Mille use ceramic?
Ceramic is harder than steel and resists scratching far better, and it keeps its colour without fading. It is also lighter than gold or steel at the same size, so a 40 mm ceramic case wears more lightly than its price suggests. The trade-off is that ceramic is brittle: it can chip on a hard impact, and a chip or crack cannot be polished out. Richard Mille treats ceramic and other advanced materials as part of its identity, and the watches are priced for the manufacturing difficulty as much as for the material.
RM07-03 40 mm or 45 mm: how do the references compare?
| Reference | Size and material | Bizak catalogue ask, 1 Oct 2026 |
|---|---|---|
| RM07-03 BonBon | 40 mm ceramic, black and golden, pre-owned | US$241,799 |
| RM07-03MARS | 45 mm ceramic skeleton | US$241,799 |
| RM07-03LIT (Litchi) | 45 mm carbon skeleton | US$767,528 |
| RM07-03MYR (Myrtille) | 45 mm carbon skeleton | US$767,528 |
The 45 mm ceramic and carbon references are sourced to order, and the spread shows how much the case material and edition drive Richard Mille pricing. The listings differ in condition and source, so use the table to see the pattern, not to value a particular watch. If you want the lower catalogue range and a smaller case, the 40 mm ceramic is the entry point in this group.
How does the RM07-03 wear?
At 40 mm in ceramic the RM07-03 is lighter than a steel or gold watch of the same size, and the rubber strap keeps it comfortable on the wrist for a full day. The skeleton dial gives it visual depth without a bulky profile. It is a watch built to be worn hard, and buyers who choose ceramic usually do so because they plan to. Try the strap and its fit before buying; Richard Mille straps are specific to the case, so a replacement comes from Richard Mille rather than from a generic strap maker.
How much is a Richard Mille RM07-03 BonBon? Prices in 2026
- Retail. Richard Mille does not publish a public price list on its website, and boutique allocations are the usual route to a new watch. Ask a Richard Mille boutique for the current price of the RM 07 reference you want.
- Bizak catalogue ask. On 1 October 2026 our sourced catalogue listed the pre-owned 40 mm RM07-03 BonBon at US$241,799, sourced to order. The 45 mm RM07-03MARS was listed at the same figure and the carbon RM07-03LIT and RM07-03MYR at US$767,528.
- What moves the price. Full set with the Richard Mille box, card and tools, an unchipped ceramic case, a recent service record, and an original strap each add. A watch without its card or with a chipped case should be priced lower.
Those figures describe what we saw and will move. Ask for a dated quote for the exact reference and set; our Richard Mille price guide explains how to compare quotes.
Is the RM07-03 a good investment?
Richard Mille watches have a strong following and a thin secondary market. A pre-owned ceramic reference is bought for the design and the materials, and a resale takes time and depends on the condition of the case and the completeness of the set. Buy it because you want it. If resale matters, ask for a written cash-buy assessment before you commit.
Buying a pre-owned RM07-03: what to check
- Provenance and paperwork. Ask for the original card, the box and proof of purchase. Richard Mille may ask for proof of provenance before servicing a watch, so keep the paperwork together.
- Serial and reference. The serial and the reference should match the card and the case back, and the edition details should be consistent with the reference.
- Ceramic case. Check the lugs, case band and bezel edges for chips or hairline cracks under good light. Ceramic does not scratch easily, so surface marks on the case warrant questions.
- Dial and movement. The skeleton dial should be clean and the rotor should wind the movement smoothly. Ask for the time-keeping result and the last service date.
- Strap and clasp. The original rubber strap should be supple with no cracks, and the clasp should be signed and functioning.
- Service history. Ask for service records and for the work done. A Richard Mille service can be expensive, so check its cost before you buy.
- Price against the band. A pre-owned RM07-03 offered far below the catalogue range needs a clear explanation of its source.

Servicing and care
Richard Mille services its own watches through its service network, linked above, and the movements are intricate, so allow time and budget for it. Keep the watch away from hard impacts on the ceramic, and rinse the rubber strap with fresh water after exposure to sweat or salt. Store it in its box away from heat.
