Trilobe band size chart by model
Trilobe prints its sizing in one long sentence, repeated across its own pages and manuals: Diameter : 40.5 mm and 38.5 mm Lug to lug : 45.5 mm (in 38.5 mm) and 48 mm (in 40.5 mm) I Lug width : 20 mm [1]. That sentence is the whole story for the strap-wearing collections: one width, 20mm, in both case sizes. The trap is the new Trente-Deux: 39.5mm case, 46.18mm lug-to-lug, and no lug width printed anywhere, because its bracelet is integrated into the case and takes no standard strap at all [6]. No consolidated Trilobe chart exists elsewhere: watchbands.ai lists 189 brands and has no Trilobe page [16].
The chart: 7 lines, one width, one gap
| Model | Case (mm) | Lug width | Lug to lug (mm) | Thickness (mm) | Strap it ships on | Notes |
|---|---|---|---|---|---|---|
| Les Matinaux | 38.5 and 40.5 | 20 mm [1] | 45.5 (in 38.5) / 48 (in 40.5) | 8.8 | leather, pin buckle | the spec line prints both case sizes, both lug-to-lugs and the one width in a single sentence |
| Les Matinaux L'Heure Exquise | 38.5 and 40.5 | 20 mm [2] | 45.5 (in 38.5) / 48 (in 40.5) | 9.2 | alligator (Blue ref), pin buckle | this page prints the line with comma decimals (9,2 / 40,5 / 38,5); the PDP makes you pick a case size at order time |
| Nuit Fantastique | 38.5 and 40.5 | 20 mm [3] | 45.5 (in 38.5) / 48 (in 40.5) | 9.2 | leather, pin buckle | same X-Nihilo three-piece case as L'Heure Exquise, one shared spec line |
| Une Folle Journee | 40.5 only | 20 mm [4] | 48 | 17.8 (X-Centric) | leather, pin buckle | one case size only, so one lug-to-lug; the thickest case in the strap families |
| Trente-Deux | 39.5 | not printed (integrated bracelet) [5] | 46.18 | 10.15 | integrated steel metal bracelet | no lug width on the page, the PDP or the manual: the bracelet is integrated and not compatible with leather straps or custom straps |
| Trente-Deux Secret | 39.5 | not printed (rubber or integrated) [7] | 46.18 (by collection) | 10.15 | rubber (rose gold ref 3203SB) or metal bracelet (steel ref 3201SB) | both Secret listings print 39.5 mm case and never a width |
| Château Trente-Deux | 39.5 | not printed (integrated bracelet) [9] | 46.18 | 10.15 | integrated metal bracelet | same case block verbatim as the sunray Trente-Deux |
The case-size to lug-to-lug split, in one table
This is the number pair nobody consolidates, and Trilobe buyers ask about it because the two case sizes look almost identical on paper. The brand's own pages pair them explicitly [1] [3]:
| Case size | Lug to lug | Lug width | Printed on |
|---|---|---|---|
| 38.5 mm | 45.5 mm | 20 mm | Les Matinaux, L'Heure Exquise, Nuit Fantastique pages and manuals |
| 40.5 mm | 48 mm | 20 mm | same sentence, same pages |
| 40.5 mm (Une Folle Journee) | 48 mm | 20 mm | collection page and manual, single-size case |
| 39.5 mm (Trente-Deux family) | 46.18 mm | not printed | collection page, product page and manual |
For wrist fit the lug-to-lug is the number that decides (see the lug-to-lug guide): 45.5 versus 48mm is a real difference on a small wrist. For strap buying it changes nothing: both sizes take the same 20mm band.
One width for everything (almost)
The strap-wearing Trilobe families all print the same figure. Les Matinaux pairs it with an 8.8mm-thick case [1], Nuit Fantastique and L'Heure Exquise with 9.2mm [2] [3], and Une Folle Journee carries a single 40.5mm case with a 17.8mm-thick X-Centric construction that still prints Lug to lug : 48 mm I Lug width : 20 mm [4]. The manuals match the pages: the Les Matinaux and Nuit Fantastique manual, the Une Folle Journee manual and the L'Heure Exquise manual all repeat the 20mm width line for line [10] [11] [12]. Strap changes are done through what the manual calls the presto spring lug attachment, an integrated quick-release system, so standard 20mm straps with spring bars work [10].
The Trente-Deux gap: no width, on purpose
The Trente-Deux, the brand's first in-house-movement watch, is the line that breaks the chart. Its pages print Thickness: 10.15 mm Diameter: 39.5 mm Lug-to-lug height: 46.18 mm and stop there [5]; the user manual prints the same case dimensions with no width either [13]. The reason is on the product page, verbatim: This bracelet is integrated into the case and is therefore not compatible with leather straps from other collections, nor with any custom-made straps [6]. Sizing is by wrist measurement, not strap width: the brand supplies a measuring-tape guide and adjusts the bracelet by adding or removing links before delivery [14]. The Trente-Deux Secret listings ship the rose gold on a rubber strap and the steel on the metal bracelet, both printing 39.5 mm case with no width [7], and the Chateau edition repeats the same block [9]. We flag the gap rather than guess a number: nothing first-party prints a width for this family.
Where Trilobe contradicts itself
Two first-party conflicts surfaced when the manuals were laid against the pages, and both are disclosed as printed, never reconciled. First, the site says the Les Matinaux and Nuit Fantastique case is Made up of 3 pieces [1] while the manual's identical spec sentence says Made up of 7 pieces [10]. Second, the site lists the case materials as 316L steel, grade 5 titanium, or 18-carat rose gold [1] while the L'Heure Exquise manual says grade 5 titanium or 18-carat rose gold or platinum [12]: steel appears only on the site, platinum only in the manual. Neither touches the 20mm width, which every surface agrees on. For collectors of verbatim detail: the Une Folle Journee manual prints Heignt: 10.2 mm, typo included [11].
Version confusion is the real trap here
Same-model version confusion is where Trilobe buyers get burned. The L'Heure Exquise page prints its spec line with comma decimals, 9,2 / 40,5 / 38,5, while every sibling page uses points [2]; the PDP then asks you to choose a case size at order time, and both choices take the same 20mm strap [8]. The Secret collection has been two different watches: today it is a Trente-Deux variant at 39.5mm on rubber or integrated bracelet [7], and older coverage of a Les Matinaux-based Secret describes a different case entirely. Le Temps Retrouve, which shows up in collection navigation, is a table clock and is excluded from this chart [18]. When in doubt, buy by the two families: 20mm if it came on leather or alligator, nothing if it came on the integrated bracelet.
How we verified this
We pulled the brand's product sitemap fresh [15], fetched every English collection page and product page (39 pages returned http 200), and downloaded all seven official PDFs linked from those pages, including the four per-collection user manuals and the bracelet adjustment guide, parsing the case blocks in each. Every number in the tables above is copied from those artifacts, not from any dealer or retailer. Unprinted values are flagged per row and never guessed: the Trente-Deux family's missing width is a real absence in the first-party record, not an oversight of this chart. Incumbents were checked fresh at build time: watchbands.ai lists 189 brands with no Trilobe entry [16], and search results for trilobe lug width surface only Trilobe's own pages and launch coverage [17].
