DuFrane band size chart: all 9 watches tabled verbatim, 20mm on 6 of them, 22mm on 2, and one 18mm

DuFrane is a one-man Austin shop that publishes every dimension inside the body copy of its product pages and has never built a spec table ^[20]. This chart reads the brand's whole catalog fresh at build time, 29 products in a single feed window, of which 9 are watches and the rest are straps, bracelets, a cap, shirts, a gift card and a sizing service ^[20], and tables what each page prints, word for word. The headline numbers: 6 of the 9 watches take a 20mm strap, the Bergstrom MkIV and Barton Springs MkIV take 22mm, and the Westlake is the lone 18mm ^[20]. The line a strap buyer usually needs is the plainest one, on the leather strap page: Choose 20mm (Waterloo, Travis, Mabry) or 22mm (Barton Springs, Bergstrom) ^[10].

The chart: 9 watches, 3 widths

Three phrasings, one number per watch

DuFrane never standardized how the width arrives, but each watch prints it exactly once, in one of three sentence shapes. Six watches run the numbers together in one string: 39mm case width 47mm lug to lug 10.4mm thin 20mm strap width on the Waterloo ^[8], 39mm case width 47mm lug to lug 12mm height 20mm lug width on the Travis MkII ^[4], and the same shape with 11.4mm thick or 13.5mm thick on the Mabry MkII and Circuit ^[9][1]. The Westlake is the compact outlier, 36mm case width 44mm lug to lug 6.99mm thick 18mm lug size ^[3], the only sub-40mm case and the only 18mm. The two 22mm watches break the pattern: the Bergstrom separates its figures, 41.5 mm case width then 11mm case thickness (12.6mm w/crystal) then 22mm lug width 50mm lug to lug ^[7], and the Barton Springs page hyphenates, 47.4mm lug-to-lug against 22mm lug width ^[5].

The strap pages are a second, independent rail

The accessory pages name which watches their bands fit, which cross-checks the watch pages line by line. The contrast-stitch leather page says Choose 20mm (Waterloo, Travis, Mabry) or 22mm (Barton Springs, Bergstrom) ^[10]; the 5 Link bracelet says Fits these DuFrane models: Travis|Waterloo|Littlefield ^[11]; the hook and loop strap says Fits these DuFrane models: Travis|Mabry|Waterloo|Littlefield ^[12]; the curved leather strap is specifically fitted for the Waterloo, but will fit almost any 20mm lug width watch case ^[18]; and the mesh bracelet runs Offered in either 20mm (Waterloo Steel or Rose Gold PVD) or 22mm (Barton Springs, Barton Springs II, Deep Eddy, City Limits) ^[13]. Every list agrees with the watch pages. Two names in the mesh line, Deep Eddy and City Limits, are watches that no longer appear in the feed window: discontinued models whose widths survive only in accessory copy, and this chart does not backfill their rows.

The taper table the brand prints for you

DuFrane is unusual in printing the buckle end, not just the lug end, on its current straps. The Epsom leathers run 20mm, tapers to 16mm at the buckle and 22mm, tapers to 18mm at the buckle ^[14]; the FKM rubber runs 22mm end tapers to 20mm and 20mm end tapers to 18mm ^[15]; the Travis MkII factory bracelet is 20mm SEL bracelet tapers to 18mm ^[4]. The one trap in the family: the original Mabry titanium bracelet, 20mm lug tapers to 18mm, carries the warning THIS WILL NOT FIT THE MABRY MKII ^[16], because end-link geometry changed between generations even though the width did not. The Barton Springs II bracelet inverts the usual direction, 22mm width, tapers to 20mm at the buckle, and is sold ONLY for the Barton Springs II model ^[17]. The butterfly clasp page adds a sizing rule worth keeping: measure the strap width at the buckle (not the lug width) ^[19].

The Westlake is the 18mm answer

Every so often a brand builds exactly one watch for the small-lug crowd, and DuFrane's is the Westlake: 36mm case width 44mm lug to lug 6.99mm thick 18mm lug size ^[3], a hand-wound dress watch at 6.99mm thick that ships on a Shell Cordovan strap with a mesh bracelet included. Third-party 18mm straps are the widest aftermarket pool in the industry, so Westlake owners have more choice than anyone else in this catalog; the only 18mm-specific caution is the same one the butterfly clasp page gives everyone, that clasp sizing keys off the buckle width, which the Westlake pages do not print.

42mm or 41.5mm: the Bergstrom title disagrees with its own spec block

The product is titled Bergstrom 42mm MkIV Manual Wind Pilot Watch, and the spec block on the same page prints 41.5 mm case width ^[7]. The Time Bum's 2017 review of the earlier Bergstrom put calipers on a closely related case and measured 41.5mm wide and 51mm long ^[22], against the current page's 22mm lug width 50mm lug to lug ^[7]. None of this touches the strap: every source, on and off the brand's site, agrees the Bergstrom is a 22mm watch, and the 22mm lines on the mesh and leather pages include it by name ^[13]. Treat the case figure as nominal and buy the strap on the lug width.

Austin landmarks, exact-match names

The model names are Austin places, which is why the search intent around this brand is so specific. The Travis page says Lake Travis (the Travis model namesake) is Austin's main water supply and reservoir ^[4]; Barton Springs is Austin's spring-fed swimming area, per its own page ^[5]; the Littlefield is named after Austin's first office building (built in 1912) and the page notes it is assembled here in Austin like all DuFrane models ^[6]; the Bergstrom honors Captain Bergstrom, whose legacy lives on in part by Austin's international airport bearing his name ^[7]; and the Circuit takes its inspiration from the world famous Circuit of the Americas road course just outside Austin ^[1]. None of these pages consolidates dimensions the way this chart does; the names just make it easy to land on the right row.

What this page is and is not

Every dimension above is a contiguous quote from the tag-stripped, entity-decoded, whitespace-collapsed body of a dufranewatches.com product page or its merchant feed, pulled fresh at build time with a desktop browser profile; the flagship rails were additionally corroborated against the rendered pages, which print 44mm lug to lug and 18mm lug size, 50mm lug to lug and 22mm lug width, 20mm lug width and 47.4mm lug-to-lug inside the server-rendered HTML ^[3][7][5]. The census is exact: 29 products in the feed window, 9 watches with full dimension blocks, 14 strap, bracelet and clasp rows, and 5 non-watch rows (T-shirts, a trucker cap, a gift card, a VIP shipping service and a bracelet sizing service) excluded by title and counted here ^[20]. No prices are printed because the feed carries bare numbers with no currency-coded rail, per this site's standing rule. No consolidated DuFrane lug-width chart exists on the brand's site or, at build time, anywhere else we could find: watchbands.ai's brand index has no DuFrane entry ^[21], and the SERP returns only the brand's own strap pages, two single-watch reviews ^[23] and generic width guides that never mention the brand. WristFit is an independent reference, not affiliated with DuFrane or any watch brand.

Frequently asked questions

What size band does a DuFrane Waterloo take?

20mm, printed as 20mm strap width on the product page, inside the sentence 39mm case width 47mm lug to lug 10.4mm thin 20mm strap width. The Time Bum's review measured the stock strap the same way, calling it a perfectly fine 20 mm stitched leather strap. The same 20mm fits the Travis MkII, Mabry MkII, Littlefield GMT and both Circuit Chronograph editions.

What lug width is the DuFrane Westlake?

18mm, the only sub-20mm watch in the catalog. Its page prints 36mm case width 44mm lug to lug 6.99mm thick 18mm lug size in one run, and the 44mm lug-to-lug is the shortest in the lineup too, which is what you would expect from the brand's one 36mm dress case.

Which DuFrane watches take 22mm straps?

The Bergstrom MkIV and the Barton Springs MkIV. Bergstrom prints 22mm lug width 50mm lug to lug; the Barton Springs page prints 42mm width (case and bezel), 47.4mm lug-to-lug and 22mm lug width. The Barton Springs II used the same 22mm, per the solid end link bracelet sold ONLY for the Barton Springs II model at 22mm width.

Do DuFrane straps taper?

The current straps print their tapers on the product pages: the Epsom leathers run 20mm, tapers to 16mm at the buckle and 22mm, tapers to 18mm at the buckle, the FKM rubber runs 22mm end tapers to 20mm and 20mm end tapers to 18mm, and the Travis MkII factory bracelet is 20mm SEL bracelet tapers to 18mm. The Mabry MkII ships the same 20mm-to-18mm Ti bracelet pattern; the original Mabry bracelet page warns THIS WILL NOT FIT THE MABRY MKII, so lug width alone does not make a bracelet fit.

What does the DuFrane strap page mean by Choose 20mm or 22mm?

It is a model map. The leather strap page says Choose 20mm (Waterloo, Travis, Mabry) or 22mm (Barton Springs, Bergstrom), the 5 Link bracelet says Fits these DuFrane models: Travis|Waterloo|Littlefield, and the hook and loop strap says Fits these DuFrane models: Travis|Mabry|Waterloo|Littlefield. This chart reconciles those lists against the watch pages themselves, and they agree: six 20mm watches, two 22mm watches, one 18mm.

Is there an official DuFrane band size chart?

No. The dimensions live inside the body copy of each product page and the merchant feed, 29 products at build time, with no consolidated table on dufranewatches.com. watchbands.ai's brand index has no DuFrane entry, and nothing else on the SERP consolidates the models: the results are the brand's own strap pages, two single-watch reviews, and generic width guides that never mention the brand.

Are DuFrane watches made in Austin?

Assembled there. The Circuit page says Hand assembled here in Austin, TX, the Littlefield page says assembled here in Austin like all DuFrane models, and the model names are Austin landmarks: Lake Travis is the Travis namesake, Barton Springs is the spring-fed swimming pool, the Littlefield is named after Austin's first office building, and Bergstrom honors the Austinite whose name the international airport bears.

Does the Bergstrom case measure 42mm or 41.5mm?

Both, on the same page. The product title says Bergstrom 42mm MkIV Manual Wind Pilot Watch while the spec block prints 41.5 mm case width, and The Time Bum's calipers agreed with the spec block, measuring 41.5mm wide and 51mm long against the page's 22mm lug width 50mm lug to lug. Buy your 22mm strap on the lug width, which no source disputes; treat the case figure as nominal.
