Corniche band size chart by model

Corniche's six watch lines need exactly three strap widths: 22mm for the Heritage 40, 20mm for the Heritage Chronograph and the La Grande Corniche, and 18mm for the Heritage 36, the Visionnaire and the Historique [1][2]. Every width is printed by the maker in the spec list on each watch's own product page, and this chart quotes those lines verbatim, spacing quirks included [5]. The maker's own strap shop sells one strap per line at the same widths, which is the cleanest corroboration a chart can have [7].

Quick answers: Heritage 40, 22mm [1]. Heritage Chronograph, 20mm [2]. La Grande Corniche, 20mm [3]. Heritage 36, 18mm [4]. Visionnaire, 18mm [5]. Historique, 18mm [6]. The strap shop backs each line with its own SKU, from Heritage 40 Strap 22mm to Historique Strap 18mm [7].

The chart: six lines, three widths, zero guessed rows

ModelBand sizeCase, as statedMovement, as statedLabel form and watch-outs
Heritage 4022mm [1]40mm x 7mm. [1]Miyota 2025 Quartz [1]Printed Lug Width: 22 mm [1], space after the colon and space before the unit, in a spec list that also carries Case Size, Dial, Crystal, Movement, Clasp, Water Resistance and Packaging lines. The 40mm x 7mm figures are case dimensions, not strap dimensions. Rose gold, steel and yellow gold colourways all carry the same line, and the maker's strap shop backs it with Heritage 40 Strap 22mm [7].
Heritage Chronograph20mm [2]39 mm x 11.5 mm. [2]Seiko VK64 Hybrid (sweeping hand) [2]Printed Lug Width: 20 mm [2] on the line the boutique overview calls its first-ever complication, a 39mm meca-quartz chronograph on the Seiko VK64 [8]. The overview page carries seven chronograph colourways from rose gold to yellow gold [8], all one width: the strap shop sells a single Chronograph Strap 20mm for the whole line [7].
La Grande Corniche20mm [3]39 mm x 11.5 mm. [3]Seiko VK64 Hybrid (sweeping hand), as printed [3]Printed Lug Width: 20 mm [3]. Two watch-outs live on this page. First, the boutique overview describes the line as automatic with an integrated steel bracelet [8], while the product page's spec list carries the Chronograph's VK64 movement line verbatim; the maker's own pages disagree with each other, and this chart records both rather than picking. Second, because the line ships on an integrated-style steel bracelet, verify the spring-bar setup before buying a leather strap; the page states the width but not the bar type. Five automatic dial variants are named on the page, Azur Bleu to Salmon [3], all at the one stated width.
Heritage 3618mm [4]36 mm - the classic size. [4]Miyota 2025 Quartz [4]Printed Lug Width: 18mm [4], the one spec line in the catalog with no space before the unit: 18mm, not 18 mm. The women's Heritage 36, 36 mm per its own spec list, is the petite version of the Heritage 40, and the four-millimeter strap difference is the whole trap of the family: identical looks, 22mm against 18mm. The strap shop sells Heritage 36 Strap 18mm separately from the Heritage 40's 22mm [7].
Visionnaire18mm [5]24 mm x 39.5 mm x 7.4 mm [5]Miyota Quartz [5]Printed Lug Width: 18 mm [5] on the rectangular Art Deco case, in the fullest spec list in the catalog: hands, hour markers, crystal coating, strap material and even strap circumference, 15,5-20 cm with a comma decimal, are all stated [5]. The 24 mm figure is the case's short side, the width across the rectangular case, not the strap width; the strap width is the separate 18 mm line. Six colourways on the overview [8], one width.
Historique18mm [6]37.5mm x 9mm [6]Miyota Quartz [6]Printed Lug Width: 18 mm [6], in a spec list that hides its width line one layer deeper than its siblings: the label carries a trailing space before the closing tag, Lug Width: with the space inside, which is why quick scrapes miss it and why parts of the third-party web list the Historique with no width at all. The page also states Strap: Genuine leather and Buckle: Classic buckle [6], and the strap shop's Historique Strap 18mm matches the spec list exactly [7].

The family split, in the maker's own spellings

The width labels in this catalog are printed in one word order, label first, but in three spellings, and the differences are real enough to trip a search: Lug Width: 22 mm on the Heritage 40, Lug Width: 20 mm on the Chronograph and La Grande Corniche, Lug Width: 18 mm on the Visionnaire and the Historique, and Lug Width: 18mm, no space, on the Heritage 36 [1][2][3][4][5][6]. The Historique adds one more quirk: its label is printed with a trailing space inside the markup, so the rendered text reads the same but the underlying line differs byte for byte from the Visionnaire's [6]. The census across every spec label on all nineteen shop pages at build finds no other width-stating form: Case Size lines carry case dimensions, the Visionnaire's Strap and Strap circumference lines carry material and wrist fit, and nothing else in any spec list carries a millimeter figure that could masquerade as a width [9]. That census ran before any width was charted, per house method, so the label inventory governs the chart and not the reverse.

What the maker's strap shop corroborates

Corniche sells replacement straps on its own site, one SKU row per line, and the names state the widths outright: Heritage 40 Strap 22mm, Chronograph Strap 20mm, Heritage 36 Strap 18mm and Historique Strap 18mm [7]. All four match the spec lists exactly, line for line, which is the strongest internal cross-check available: two independent surfaces on the maker's own site, product spec list and strap shop, agree on every line both cover. Note the gaps the strap shop reveals: no first-party strap exists for the La Grande Corniche, consistent with its integrated bracelet, and none for the Visionnaire, which ships on a Japanese cotton-hemp strap by Fujikinbai [5].

What the dealers say, and why it is not the basis

Dealer and review pages carry per-model statements that agree with the maker's spec lists, and they are cited here as corroboration only, in their own class, never as the chart's basis. The Watch Library's Heritage 40 blue dial page lists Lug width 22mm in its spec block [10]. KeepTheTime's Heritage 40 rose gold page states Brown croc style leather strap / 22mm lugs [11]. The Watchdrobe's Heritage 40 RG Black page reprints the maker's own block, Lug Width: 22 mm included [12]. Watchard's database entry gives Case width 40 mm Strap width 22 mm [13]. Two long-form reviews add texture on the strap itself: WatchReport notes the Heritage 40 strap runs 22mm at the lugs and tapers to 20mm near the tail and buckle [14], and 12and60 measures the same 22mm at the lugs, reducing to 20mm at the clasp, with one unit measuring more like 21mm at the bottom lug [15]. The taper matters when you shop: a replacement strap at a straight 22mm will sit slightly proud at the buckle end compared with the stock tapered strap. Every one of these rows cites a Heritage 40; no dealer page surfaced at build states a width for any other Corniche line, which is precisely why the first-party spec lists are the only basis for this chart.

Why no chart existed

Nobody has consolidated this catalog, including the aggregators that consolidate everyone else's. Search at build, two runs, surfaces the maker's own pages, dealer listings that each carry one model's width, and reviews of single watches; none carries a per-line width table [16]. watchpolice serves nothing at /brands/corniche, /brands/corniche-watches or /brands/corniche-watch, all 404; its /brands/la-grande-corniche slug returns 200 with about 32KB of shell markup and zero lug-width content, the same soft-404 shell class, and no Corniche spelling appears in its brands sitemap of 950 locations while Seiko and Rolex controls are present [17]. watchbands.ai's brand index lists 196 brands at build with Seiko, Rolex and Citizen present and Corniche absent by slug and by whole-word text [18]. The gap this page fills: all six lines on one table, the family split laid out in the maker's own spellings, and the strap-shop and dealer evidence kept in clearly separated classes.

How we verified this

On 2 October 2026 we pulled the maker's sitemap index and all sub-sitemaps fresh, 212 locations total, and swept every page under /shop/, nineteen product pages, with a browser user agent [9]. The label census ran first: across all spec lists on all nineteen pages, the only width-stating labels are the six Lug Width lines quoted above, and the histogram of every other millimeter-bearing label, Case Size on five pages, Case Thickness on one, Strap circumference on one, found no form that could be mistaken for a strap width. The catalog was completed with the WooCommerce product feed, thirteen items that reconcile with the sitemap's shop pages, and the boutique overview, which carries the live variant cards [8]. Non-watch pages, bracelets, straps, clasps, watch rolls, sunglasses, a keyring, a gift shop, spare parts and two books, were excluded by what they are; the dead placeholder page heritage-40-36, an out-of-stock Uncategorized SKU with no specs, is recorded rather than charted [9]. The maker's strap shop was pulled to corroborate each line, and six dealer and review pages were pulled fresh and are cited in their own class [10]. The incumbent walls were fired fresh at build, not inherited: the watchpolice slug probes in four spellings with the shell adjudication on the 200 page, the 950-location brands sitemap grep with Seiko and Rolex controls, the watchbands.ai index walk with three controls, and two web searches [16]. Every quoted spec span on this page was machine-checked verbatim against the saved pulls.

Related guides

The lug width chart by brand places Corniche's 18/20/22 split beside every other brand on this site, and the master band size chart indexes them all. Because the Heritage 36 and Heritage 40 look identical and take different straps, the measuring guide is worth a read before ordering either. For the case figures that keep getting mistaken for widths, the Visionnaire's 24 mm short side being this catalog's own example, see lug-to-lug, explained, and the watch database lists every charted brand by width.
