Meissen is a porcelain manufactory. Grand Feu is a traditional enamel technique. The manufacturers’ own descriptions support a clear comparison of how each dial is made. They do not establish which surface is tougher, more scratch resistant, easier to repair, or cheaper to service, so this article does not rank them on those points.
Two names that describe different things
“Meissen” refers to the MEISSEN porcelain manufactory and the porcelain it produces. The manufactory’s own history page states that its first successful firing of European hard porcelain took place on 15 January 1708, and that Augustus the Strong founded the Royal-Polish and Electoral-Saxon Porcelain Manufactory on 23 January 1710 (MEISSEN, “History”). In a watch context, the name matters because the 2025 Glashütte Original Senator Meissen uses porcelain discs for its dials.
“Grand Feu” is not a brand. Ulysse Nardin uses the term for traditional enamel: enamel powder applied to a copper dial plate and fired repeatedly (Ulysse Nardin, “Savoir-Faire: Enameling”). Porcelain is a ceramic body, and enamel is a fused mineral layer on metal. Calling a porcelain dial “enamel” blurs that distinction, and the two should be compared as separate constructions.
How each dial is built
Porcelain dial: the Senator Meissen example
MEISSEN identifies kaolin as the core ingredient. Its craftsmanship page states: “Kaolin, a fine white clay, is the essential raw material for making white porcelain.” The same page describes porcelain paste made from kaolin, feldspar, and quartz, and says glaze firing forms a glass-like protective surface (MEISSEN, “The Craftsmanship of the MEISSEN Porcelain Manufactory”).

For the Senator Meissen, Swatch Group describes the sequence as follows (Swatch Group, “Glashütte Original x MEISSEN” (2025)):
- Razor-thin porcelain discs are fired at 1,400°C.
- The fired discs are decorated and lettered by hand, in layers.
- Each decorative layer is fired at 900°C.
These steps describe this collaboration. They are not a universal recipe for porcelain watch dials.

Grand Feu enamel dial
Ulysse Nardin describes the traditional process as enamel powder applied to a copper dial plate, then fired around 800°C, with the firing repeated (Ulysse Nardin, “Savoir-Faire: Enameling”). Patek Philippe describes enamel more generally as a powdered mixture of minerals and metal oxides fused to a metal surface through repeated kiln firings (Patek Philippe, “The Art of Enameling”). The sequence for a plain Grand Feu dial is:
- A copper dial plate is prepared as the base.
- Enamel powder is applied to the plate.
- The plate is fired at around 800°C.
- Application and firing are repeated. The number of firings is not stated in the Ulysse Nardin source.
Firing temperatures: what the numbers do and do not tell you
Each temperature below belongs to one named process and one named source. Temperatures are process conditions set by the material being fired. A higher figure does not show that a dial is better or more durable.

| Process | Stated temperature | Source and context |
|---|---|---|
| Senator Meissen porcelain discs | 1,400°C | Swatch Group, 2025 release, for this collaboration |
| Senator Meissen hand-applied decorative layers | 900°C per layer | Swatch Group, 2025 release, for this collaboration |
| Traditional Grand Feu enamel on copper | Around 800°C, repeated firings | Ulysse Nardin, undated craft page; number of firings not stated |
| Blancpain porcelain dial, vitrification firing | 1,300°C, second firing lasting 24 hours | Blancpain, “Métiers d’Art: Porcelain” (2019); this describes Blancpain’s own process |
The Blancpain entry shows that porcelain and enamel can appear in one dial-making process. Its 2019 document describes a hand-crafted porcelain dial with enamel applied by hand and a second 24-hour firing at 1,300°C to vitrify the porcelain (Blancpain, “Métiers d’Art: Porcelain” (2019)). That treatment is Blancpain’s; it is not the standard for every porcelain dial.
Decoration and variations
- Layered hand decoration on porcelain. The Senator Meissen dial carries hand-applied lettering and Roman numerals built up in layers, each fired separately (Swatch Group, 2025).
- Plain Grand Feu enamel. A single enamel field on copper, built up through repeated firings (Ulysse Nardin).
- Cloisonné enamel. Patek Philippe documents a cloisonné example with gold-wire compartments filled with enamel. Cloisonné is a separate technique from plain enamel and should not be treated as the same construction.
What the manufacturers claim about finish and wear
The sources make a few performance claims, and each one is limited to the manufacturer who made it.

No comparative test of a porcelain dial against a Grand Feu dial appears in these manufacturer materials, and no independent comparison was found. The claims above therefore cannot be used to rank the two surfaces. Patek Philippe’s enamel description covers technique, not durability, and MEISSEN’s glaze statement covers porcelain in general, not this watch.

Questions to ask before choosing a porcelain or enamel dial
- Is the dial porcelain, enamel on copper, or another material? Ask for the material by name, not “porcelain-style” or “enamel-style.”
- Is the enamel plain or cloisonné? These are different constructions.
- Does the seller state firing temperatures, and is the figure attributed to a named process or a named manufacturer?
- What does the written warranty say about dial damage, and who performs dial repairs?
- Is the watch a limited edition? Confirm whether that affects service parts or the repair path.
Answers to these questions show what a particular watch is made of and how it is documented. They do not settle which surface will last longer on the wrist.
The clearest factual difference is composition and process. Porcelain is a fired ceramic body, with a glaze layer over it, and the Senator Meissen builds its decoration in hand-applied fired layers. Grand Feu is fused enamel powder on a copper plate, built through repeated firings. Neither manufacturer’s material shows which construction resists impact, scratches, or wear better, so buy on the design, the decoration, and the service terms you can verify.
