Summary of Key Points about Modified Richard Mille RM055 – Vaucher vs. Parmigiani Fleurier Movements
Based on the latest video transcript (comparing two Richard Mille RM055 watches – Japanese limited edition vs. Asian limited edition), here are the essential differences and selection guidance for modified RM055 movements.
1. Two Watches, Two Movements
- Left watch (Japanese limited edition): Uses the Vaucher movement (cost‑effective, very popular)
- Right watch (Asian limited edition): Uses the Parmigiani Fleurier movement (higher quality, more expensive)
2. Movement Similarities
- Both achieve full functionality
- Gear positions are completely the same
3. Vaucher Movement – Cost‑Effective (90‑95% Similarity)
- Sells very well; craftsmanship recognized in the market
- Differences are in details compared to genuine:
- Central axis bearings: Gray and not very obvious – does not match original process
- Central shafts and screws have differences
- Pentagonal screws: Less three‑dimensional
- Pull rod and small screw craftsmanship: Slightly worse
- Back snap ring (spring): Slightly thicker
- Central axis on back: Not layered, gray
- Non‑calibrated shock absorber: Almost flush with balance wheel (genuine/Parmigiani has it lower, with a small gap)
4. Parmigiani Fleurier Movement – Premium (Nearly Indistinguishable)
- Can be almost indistinguishable from the genuine
- Central axis: Layered with a small protruding dot in the middle – correct genuine‑level craftsmanship
- Screw hole positions: Match genuine in size
- Pentagonal screws: More three‑dimensional and delicate
- Pull rod area: Very delicate – screws and bridges perfect
- Back snap ring: Layered and very thin
- Free‑sprung area: Smaller than balance wheel; pentagonal screws very clear – meticulous craftsmanship
- Non‑calibrated shock absorber: Sits lower than the balance wheel (correct; Vaucher is flush)
5. Cases – Both High Quality
- Both watches use cases developed with original data – imported NTPT carbon fiber
- Texture is quite fine; case craftsmanship is very good
6. Selection Advice
- Choose according to needs and budget
- Vaucher: Cost‑effective, 90‑95% similarity, good enough for most
- Parmigiani: Premium, nearly perfect details, but relatively expensive
7. Key Comparison Checklist – RM055 Movements
| Feature | Vaucher Movement | Parmigiani Fleurier Movement |
|---|---|---|
| Central axis bearings | Gray, not obvious | Layered, with protruding dot |
| Pentagonal screws | Less 3D | Very 3D, delicate |
| Pull rod / bridge | Slightly worse | Perfect, delicate |
| Back snap ring | Thicker, not layered | Layered, very thin |
| Free‑sprung balance height | Flush with balance wheel | Lower than balance wheel (correct) |
| Overall similarity | 90‑95% | Nearly indistinguishable |
| Price | Cost‑effective | Expensive |
| Suitability | Budget‑conscious buyers | Perfectionists / higher budget |
Concluding Comment
This video provides a clear, side‑by‑side comparison of the two main movement options for modified Richard Mille RM055 watches: the Vaucher movement (cost‑effective, 90‑95% similarity) and the Parmigiani Fleurier movement (premium, nearly indistinguishable from genuine). Both movements achieve full functionality and have the same gear positions. The differences lie in the details: central axis bearing construction (layered with protruding dot on Parmigiani vs. gray and indistinct on Vaucher), pentagonal screw three‑dimensionality, pull rod finishing, snap ring thickness, and the height of the free‑sprung balance relative to the outer ring (Parmigiani sits lower – correct; Vaucher is flush – incorrect). Both cases are high‑quality NTPT carbon fiber developed from original data.
For the budget‑conscious buyer: The Vaucher movement offers excellent value and is very popular, though a trained eye will spot the detail differences.
For the perfectionist with a higher budget: The Parmigiani Fleurier movement is the clear choice – its craftsmanship, central axis detail, and free‑sprung balance height are correct to the genuine.
Bozwatch’s advice is practical: choose according to your needs and budget. The video’s detailed comparison (central axis, screws, pull rod, snap ring, balance height) provides an invaluable checklist for anyone navigating the RM055 modification market. As always, independent verification of the movement type is recommended. This is the definitive guide to understanding RM055 movement tiers.
Hello everyone, this is Bozwatch Reviews.
Every watch is a work of art, a testament to time, and I am a fan of them. I also hope that all watch enthusiasts can avoid pitfalls and find their own “Bole” (discerning patron).
Some fans have messaged me privately wanting to buy the best modified Richard Mille RM055 currently available. But the movements of the RM055 on the market are very difficult to distinguish – there are many, their craftsmanship varies greatly, and prices are also very different. So they asked me to make a video to help identify what kind of RM055 modification is suitable for you, and what the best RM055 modification looks like.
In fact, you can see that for the two RM055 watches in my hand – the one on the left is a Japanese limited edition, and the one on the right is an Asian limited edition. The movements used in the two are different.
The one on the left uses the most popular Vaucher movement on the market. The one on the right uses a better movement – modified from a Parmigiani Fleurier movement.
The Vaucher movement is currently very cost‑effective, but there are some detail differences compared to the genuine. The Parmigiani movement can be almost indistinguishable from the real one, but its drawback is that it’s relatively expensive. This mainly depends on your personal choice.
So, what are the specific differences between these two movements? Let’s take a look.
Both movements achieve full functionality, and their gear positions are completely the same. The Vaucher movement sells very well, and its craftsmanship has been recognized in the market – it’s still very good. But it can only reach 90% or 95% similarity to the genuine. The differences are mainly in the details.
What are the specific differences? You can see that for a gear like this, the central axis bearings are very important. On a Vaucher movement, the bearings of each gear’s central axis are gray and not very obvious – that doesn’t match the original process.
Now look at the Parmigiani caliber – its central axis is layered, with a small protruding dot in the middle. That’s the correct process matching the genuine. Let me zoom in. You can see the Vaucher movement’s central axis is gray – whether it’s these two shafts or all the other central shafts, including the screws, there are still some differences compared to the genuine.
The Parmigiani movement’s central axis is very well done – that’s the genuine‑level craftsmanship. The screw hole positions also match the genuine in size. The pentagonal screws on the Parmigiani are more three‑dimensional, while the Vaucher’s are not as delicate.
If you really understand watch movements, you can see that the Parmigiani is a true one‑to‑one reproduction, while the Vaucher has subtle differences.
Look at the pull rod – the area from the upper triangle to the lower part. On the Parmigiani, the pull rod is very delicate – the screws and bridges are all perfect. On the Vaucher, the pull rod and the small screw craftsmanship are slightly worse. These details determine the price – the difference between the two movements is significant.
Now let’s look at the back. The central axis of each gear on the back is different. The most important difference is the snap ring (spring). On the Parmigiani, the snap ring is layered and very thin. The free‑sprung (non‑caliber) area is smaller than the balance wheel, and the pentagonal screws are very clear – meticulous craftsmanship.
What does the Vaucher look like? Its snap ring is slightly thicker. The hole here is not layered, and the central axis is gray. Its non‑calibrated shock absorber almost fits flush – but on the genuine (like Parmigiani), the non‑calibrated part is lower than the balance wheel, with a small gap. On the Vaucher, it’s completely flush. Still, this Vaucher movement is very popular and sells well on the market.
Now let’s look at the cases. Both cases are developed with original data – the best NTPT carbon fiber cases. The texture is quite fine. The case craftsmanship is really quite good – very OK.
If you want to choose an RM modified watch, you must choose a carbon fiber case with very good texture. According to the merchant, these cases are all imported, using original data – the same as the genuine. Such cases are still quite good.
This is a simple explanation and comparison of the Vaucher and Parmigiani Fleurier movements. When choosing a modified RM055, you must be careful. Choose according to your needs and budget.
