Baltic band size chart: all 63 watches tabled verbatim, 20mm on every single one

Baltic publishes its dimensions in a Specifications block on every product page and has never consolidated them into one table [65]. This chart reads the whole live catalog fresh at build time, 101 product URLs in the sitemap of which 63 are watches with printed lug rails, 37 are straps and accessories, and one is a 60mm stopwatch with no lugs at all [65]. The headline is the flattest width profile in this site's database: every one of the 63 watch pages prints the identical rail, Lug width: 20mm, while the lug-to-lug quietly splits into four values, 44, 45, 46 and 47mm, by family [2]. The line a strap buyer needs is on the Aquascaphe Classic Blue Gilt: Case diameter: 39mm Lug to lug: 47mm Thickness: 13mm (11mm without glass) Lug width: 20mm [2].

Quick answer: a 20mm strap, for every Baltic watch currently sold, no exceptions. Lug-to-lug is where the families differ: 44mm on the MR and Prismic, 45mm on the Heures du Monde and the 37mm Aquascaphe MK2 (the MK2 pages print a dual 45mm or 47mm line, see below), 46mm on the Hermetique and HMS 003, 47mm on everything else. Factory straps taper 20mm at the lugs to 16mm at the buckle.

The chart: 17 families, 63 watches, one width

One width, four lug-to-lugs

The width column above never changes, so on a Baltic the strap question is answered once and the fit question is answered by the lug-to-lug. Four values cover the whole catalog [65]. At 44mm sit the two 36mm dress families, MR Classic and MR Roulette, whose pages print Case diameter: 36mm Lug to lug: 44mm Thickness: 9.9mm (8mm without glass) Lug width: 20mm [45], and the Prismic lines at the same numbers with a slimmer case, Thickness: 9.2mm (7.4mm without glass) on the Stone dials [57]. At 45mm sits the Heures du Monde worldtimer: Case diameter: 37mm Lug to lug: 45mm Thickness: 11.3mm (9.3mm without glass) Lug width: 20mm [34]. At 46mm sit the whole Hermetique line, Case diameter: 37mm Lug to lug: 46mm Thickness: 10.8mm (8.3mm without glass) Lug width: 20mm [23], and the smaller HMS 003 chronograph. At 47mm sits everything diver-shaped plus the HMS 002 and the Scalegraph: the 41mm titanium divers are the biggest cases in the catalog and still print Case diameter: 41mm Lug to lug: 47mm Thickness: 13,3mm (11mm without glass) Lug width: 20mm [4], while the reworked 2026 Scalegraph prints Case diameter: 39.5mm Lug to lug: 47mm Thickness: 14.1mm Lug width: 20mm [59]. Hen & Mills measured the revision the same way, spanning 47mm lug tip to lug tip on 20mm lugs, and called the lugs 20mm quietly the most useful number here [70]; aBlogtoWatch's hands-on agrees on a modest lug-to-lug length of 47mm [71].

The MK2 double line, printed as printed

The Aquascaphe MK2 is the only Baltic sold in two case sizes from one page, and its spec block prints both numbers as a pair: Case diameter: 37mm or 39.5mm, then Lug to lug: 45mm or 47mm, then Thickness: 12.9mm (10.7mm without glass) and Lug width: 20mm [18]. The body copy repeats the pairing, a 45mm or 47mm lug to lug over the two bezel sizes, and the page metadata sells it as available in 37mm and 39.5mm [18]. We probed every first-party surface at build time for the per-size split, the variant selector buttons (37mm and 39.5mm), the variant URLs, the brand's own user guide for the MK2, and the embedded product data: none of them separates which case carries which length. So this chart tables the dual line verbatim and does not assign 45mm to the 37mm or 47mm to the 39.5mm on its own authority. The one published attribution we found, Delugs' MK2 strap guide, lists the 39.5mm Warm Silver with Lug to lug: 47mm and Lug width: 20mm [75], which is consistent with the shorter case carrying the shorter length, but it is a strap seller's spec block, not a Baltic rail, and it is flagged here as exactly that.

The archive trap: three GMT URLs, one rendered page

The sitemap lists aquascaphe-gmt-grey, aquascaphe-gmt-green and aquascaphe-gmt-orange as three product URLs, but all three render the same archived page: the canonical is /en/archives/aquascaphe-gmt and the title is Aquascaphe GMT Grey on every one of them [12]. If you are matching a strap order against a saved link for a green or orange GMT, read the rendered page, not the address bar. The rails are unaffected: the archived page prints Diameter: 39mm Lug to lug: 47mm Thickness: 13mm (11,2mm without glass) Lug width: 20mm, French decimal comma included [12]. Those commas are deliberate throughout this table: Baltic is a French brand and several pages print 36,5mm and 11,9mm; this chart reproduces them as printed rather than normalizing [41].

Factory straps: the 20/16 taper

Because every watch takes 20mm, Baltic sells one strap program for the whole catalog, and the strap pages print both ends of the taper. The stitched calf straps list Material: Calf leather Lug width: 20 mm Width at the buckle: 16 mm Length: 115/75mm (fits 15 to 20cm wrists) [66], and the Rubber FKM sport straps print the same Lug width: 20 mm Width at the buckle: 16 mm pair [67]. Of the 37 accessory pages in the sitemap, 26 print a width rail and every one of them is 20mm, with 22 also printing the 16mm buckle [65]. The steel bracelets (beads of rice, flat link, mesh) print the 20mm lug width and no buckle width; the buckles and watch rolls print no width at all, which is why they carry no rows here.

The one watch with no lugs

The Rally Timer Tour Auto 2026 Limited Edition is a 60mm flyback stopwatch in the catalog but not in the roster: its page prints Diameter: 60mm Thickness: 18mm, a numbered caseback, and no lug width or lug-to-lug anywhere [64]. There is no spring-bar gap to size a band against, so assigning it 20mm by brand association would be inventing a number. It stays out of the 63.

What the incumbent strap guides cover, and what they do not

Baltic strap queries already have sellers ranking on them, and their Aquascaphe coverage is accurate: CNS Watch Bands writes that Every Baltic Aquascaphe reference uses 20mm lugs and sells against the Classic, MK2, Bronze and GMT [72], with a dedicated GMT guide repeating the point across all four colourways [73]. Delugs runs a Best Straps for the Baltic Aquascaphe guide built on its 20mm lug width [74] plus the MK2 strap guide quoted above [75], and Barton sells a quick-release band listed for the Baltic Aquascaphe family (Classic, Bronze, GMT, Dual-Crown, Titanium) and the Bicompax chronographs [76]. What none of them tables is everything else: Hermetique, Heures du Monde, HMS, MR, Prismic and Scalegraph appear on none of those pages, and no consolidated brand-wide chart existed at build time on baltic-watches.com or anywhere else we could find, by Brave search and a second search method. watchbands.ai's brand index has no Baltic entry [77].

What this page is and is not

Every dimension above is a contiguous quote from the tag-stripped, entity-decoded, whitespace-collapsed text of a baltic-watches.com product page pulled fresh at build time with a desktop browser profile, 101 pages in the sitemap window, zero missed width-bearing watch pages and zero re-typed numbers; the strap-page rails quoted with a space (20 mm) are reproduced with that spacing as printed [66]. The catalog census is exact: 63 watches with lug rails, 37 accessories, 1 lugless stopwatch [65]. No prices are printed because the pages carry euro amounts only inside cart widgets, not in the specification rails this chart quotes. Press numbers are cited as corroboration only and never override the product page: Hodinkee's Prismic launch piece prints The lug width is 20mm, and the lug-to-lug is 44mm [69] and Monochrome's Prismic Stone piece prints Lug-to-lug is 44mm, and the thickness is 9.2mm [68], both matching the first-party rails above. WristFit is an independent reference, not affiliated with Baltic or any strap seller.

Frequently asked questions

What size band does a Baltic Aquascaphe take?

20mm, on every Aquascaphe ever listed in the current catalog: Classic, Titanium, Bronze, Dual-Crown, GMT, GMT MK-II and the MK2, 21 watch pages in total, and every one prints Lug width: 20mm. The strap sellers who already cover the diver family (CNS, Delugs, Barton) say the same thing for the Aquascaphe lines they list.

Do any Baltic watches take a lug width other than 20mm?

No. All 63 watch product pages in the baltic-watches.com sitemap at build time print the identical rail, Lug width: 20mm. There is no 18mm, 19mm, 21mm or 22mm watch in the current catalog, which makes Baltic the flattest width profile of any brand charted on this site.

What is the lug-to-lug of the Aquascaphe MK2?

The product pages print a dual value verbatim: Lug to lug: 45mm or 47mm, next to Case diameter: 37mm or 39.5mm. Baltic sells the MK2 in two case sizes from one page and does not break the lug-to-lug out per size anywhere first-party (product page, variant selector, user guide), so this chart prints the dual line as printed and does not guess the split. Delugs strap guide attributes 47mm to the 39.5mm Warm Silver, which is consistent with the smaller case carrying the shorter length, but it is a third-party attribution, not a Baltic rail.

What lug width is the Baltic Prismic?

20mm, both the standard Prismic and the Prismic Stone. The Stone pages print Case diameter: 36mm Lug to lug: 44mm Thickness: 9.2mm (7.4mm without glass) Lug width: 20mm, and Hodinkee corroborates in prose: The lug width is 20mm, and the lug-to-lug is 44mm.

What size strap fits the Baltic HMS and MR?

20mm, like everything else. The HMS 002 prints Case diameter: 38mm Lug to lug: 47mm Thickness: 13mm (10mm without glass) Lug width: 20mm, the HMS 003 prints Case diameter: 36,5mm Lug to lug: 46mm (French decimal comma as printed), the MR Classic and MR Roulette both print Case diameter: 36mm Lug to lug: 44mm. Same strap, four different lug-to-lugs.

Do Baltic factory straps taper?

Yes, 20mm to 16mm. The strap product pages print both ends, for example Material: Calf leather Lug width: 20 mm Width at the buckle: 16 mm on the stitched straps, and the same pair on the Rubber Classic and Rubber FKM sport straps. So a factory-width replacement keeps a 16mm buckle; a straight 20/20 strap will also fit the lugs.

Is there an official Baltic band size chart?

No. The dimensions live in a Specifications block on each product page and there is no consolidated table on baltic-watches.com. The strap sellers who rank for Baltic queries cover the Aquascaphe family only: CNS Watch Bands publishes Aquascaphe and Aquascaphe GMT guides, Delugs an Aquascaphe guide and an MK2 strap guide, and Barton sells Aquascaphe/Bicompax bands. None tables Hermetique, Heures du Monde, HMS, MR, Prismic or Scalegraph.

What about the Rally Timer Tour Auto 2026?

It is a 60mm dashboard-style stopwatch with no lugs: its page prints Diameter: 60mm Thickness: 18mm and no lug lines at all. It is excluded from the 63-watch roster rather than assigned a width; there is no spring-bar gap to size a strap against.
