Doxa band size chart by model

No brand hides the strap size in the name as thoroughly as DOXA. The SUB 200 is 19mm [1] [3], the near-identical-looking SUB 300 and SUB 300T are 20mm [15] [17], the smaller-named SUB 200T is 18mm [7] [8], and the big SUB 750T and SUB 1500T are both 21mm [23] [26], a width most strap makers barely stock. The depth-rating name tells you nothing about the lug gap: the 200-meter SUB 200 II is 20mm while the 300-meter SUB 300 is also 20mm, and the 600-meter SUB 600T is 20mm too [9] [18]. This chart pins every SUB family to its measured lug width with DOXA's own spec lines plus a second independent surface on every row, and it carries the three traps that generate most wrong Doxa strap orders: the 19mm SUB 200 with its 20mm-wide bracelet, the SUB 300 bracelet that looks like 22mm but seats on 20mm, and the one 300T that takes no standard strap at all.

Quick answers: SUB 200T (39mm) takes 18mm. SUB 200 (42mm) takes 19mm, not 20mm. SUB 200 II (44mm) takes 20mm. SUB 200 T.GRAPH II takes 20mm. SUB 300 and SUB 300T (42.5mm) take 20mm, whatever the bracelet looks like. SUB 600T takes 20mm in both eras. SUB 750T (45mm) takes 21mm. SUB 1500T (45mm) takes 21mm and its bracelet is held by screws. Vintage steel SUB 300T takes 20mm. The 2002 SUB 300T Reissue takes no standard strap: read the reissue section before buying anything for it.

The name game, and where it breaks

The SUB number is a depth rating, not a size: SUB 200 means 200 meters, SUB 1500T means 1,500. Because most of the line wears the same cushion case, buyers assume one width fits all, and the strap-shop guide that anchors this space opens with exactly that warning: identify the specific reference before ordering, because the range spans several case sizes with different lug widths [3]. The rule that works most of the time is: 20mm on the standard steel cushion case, one step down on the small models, one step up on the big ones. It breaks in the places a chart exists for. The SUB 200 II grew to 44mm and 20mm lugs while its 42mm sibling kept 19mm, so two current watches named SUB 200 take different straps [9] [1]. The current SUB 600T shrank to 40mm while keeping 20mm lugs, but the strap-shop tables still group it with the 42.5mm 300T case [18] [3]. And the 45mm models split by depth rating: 750T and 1500T are 21mm, while the older 1000T and 1200T at the same 45mm class were 20mm [23] [30].

The chart: 13 verified rows

Every row carries at least two independent surfaces: DOXA's own product and strap pages (the Lug width spec line), the strap-trade fitment guides, dealer listings with printed specs, or owner measurements published in reviews. Widths are the spring-bar gap at the case, the first number of a strap listing. Where a widely repeated table blurs a row, the blur is named rather than charted.

SUB 200T (current, all 39mm variants)39 mm18 mmDOXA's product page prints Lug width 18.00 mm and the hands-on reviews agree; the slimmest Sub, and the only 18mm one [7] [8] [3]
SUB 200 (all 42mm variants, 2019 on)42 mm19 mmthe odd-width row: 19.00 mm on DOXA's product and strap pages, confirmed by the fitment guides; the factory bracelet still runs 20mm wide at its end link, see the 19mm section [1] [2] [3] [4]
SUB 200 II (current, 44mm, fume dial)44 mm20 mmthe successor moved 42 to 44mm and 19 to 20mm, on DOXA's spec line and every launch review; a 20mm strap for the II does not fit the 42mm original [9] [10] [11] [12]
SUB 200 T.GRAPH II (current chronograph)42 mm20 mmthe 2026 chronograph revival: 20mm per the launch specs and the reference database; a different watch from the older 43mm T.GRAPH, treat that generation separately [13] [14] [39]
SUB 300 (current, 42.5mm, all colors incl. Carbon and Ti)42.5 mm20 mmDOXA prints Lug width 20.00 mm on the product page and the same figure on every strap SKU; the fitment guide and database agree, and the titanium and carbon editions hold the same 20mm [15] [16] [3]
SUB 300T (current, 42.5mm, 1,200m)42.5 mm20 mmsame 20mm width as the SUB 300 despite the helium valve and thicker case; the bracelet's false taper makes it look wider, order 20mm [17] [3] [39]

SUB 750T (current, 45mm, 2025 on)45 mm21 mmDOXA's page prints Lug width 21.00 mm and both Hodinkee pieces confirm; an odd width, so check strap stock before choosing a design [23] [24] [25]

The 19mm SUB 200, and the lyre-lug question

The SUB 200 is the trap this chart exists for. Its case is 42mm against the SUB 300's 42.5mm, the two watches are visually near-twins, and the width differs: 19mm versus 20mm. An owner review states the problem flatly: the case has a 19mm lug spacing, which is odd enough on its own, but particularly so because the bracelet is 20mm wide, so a visible width jump sits between the end link and the first bracelet link, a compromise the reviewer could find no sensible reason for [5]. That jump is why so many sellers and buyers file the SUB 200 as a 20mm watch. One widely copied specs table even prints the SUB 200 row as 18 to 20mm depending on strap, a blur this chart refuses to repeat: the spring bar gap is 19mm, full stop [38] [1].

The lyre lugs soften the practical blow. A comparison thread of the SUB 200 against the SUB 600T documents that a 20mm NATO goes onto the 19mm lugs just fine, and that the real difficulty is the opposite one: the lugs are so short that aftermarket bracelets, which need lug depth to seat their end links, are the hard fit on this watch [6]. Owners also run 20mm tropic and rubber straps on it for the same reason. So the working advice is: 19mm for any two-piece strap you intend to keep on the watch, and a thin 20mm one-piece is an accepted owner workaround, not the spec. The same review thread that documents the workaround also notes the SUB 200's factory FKM strap comes in two factory lengths, 125 x 75mm standard and 110 x 65mm small, both at 19mm [2], which is the number that matters when you order.

The SUB 300 false taper: why it measures 22mm and seats 20mm

The most common wrong Doxa order is a 22mm strap for a SUB 300. The watch genuinely looks like a 22mm candidate on the wrist: the beads-of-rice bracelet's end section flares past the lugs and presents a wider face than the spring bar gap underneath it. The strap-trade guide names the mechanism exactly: the SUB 300's bracelet has a false taper starting at 22mm that extends beyond the actual 20mm lugs, creating the appearance of a wider lug, while the actual spring bar gap is 20mm, so the order size is 20mm [3]. DOXA's own pages settle it: the SUB 300 product spec and every SUB 300 strap SKU print Lug width 20.00 mm [15] [16]. The same holds for the SUB 300T [17]. A 22mm strap will not compress into a 20mm gap; it simply returns. For how DOXA-size tapers run from lug to buckle, the strap taper guide covers the notation.

21mm at the top: the 750T, 1500T and 5000T club

Every current 45mm SUB takes 21mm, which is the least-stocked of the common widths. The relaunched SUB 750T prints Lug width 21.00 mm on DOXA's page, and the launch coverage and hands-on review both carry the same figure, the reviewer's one complaint being that the 21mm lug width means buying a whole new set of NATO straps [23] [24] [25]. The SUB 1500T matches it: DOXA's own rubber and steel strap SKUs for the line print Lug width 21.00 mm [26] [27], and the fitment guides and dealer listings agree [28] [29]. One hardware note unique to the 1500T: DOXA's bracelet listing describes the beads-of-rice bracelet as attached by screws, so budget for the screwdriver, not just the strap [27]. The discontinued 45mm SUB 5000T ran 21mm as well [30] [31], but note the era split: its 45mm contemporaries the SUB 1000T and 1200T were 20mm [30] [22], so big-case equals 21mm is a current-catalog rule, not a vintage one.

The one SUB this chart refuses: the 2002 SUB 300T Reissue

One DOXA deliberately fails the chart: the 2002 SUB 300T Reissue, the limited run that relaunched the brand. It does not take a standard width at all. The definitive owner archive records its lug width as 12mm and states the consequence plainly: there were virtually no aftermarket bracelets or straps available for the watch [35]. A second page of the same archive, reviewing it against the Dreadnought, gives the actual lug width as only 14mm, with a 22mm-wide bracelet riding on those narrow mounting points [36]. The two figures disagree, 12 versus 14mm, and since both come from the same measuring owner, this chart refuses the row entirely: measure before buying anything for a 2002 Reissue. What is not disputed is the design intent: in the brand's own forum answers at the time, DOXA's Rick Marei described the reissue as almost identical to the later SUB 750T except for the proprietary lugs, the exact word, proprietary [37]. Owners did fit modified Seiko bracelets and trimmed rubber straps to it [35] [21], but that is a project, not a purchase. Every other modern SUB on the chart uses ordinary spring bars; for the tool side, see the spring bar tool guide and the spring bar size table.

Name traps that change the strap

Four current names, four answers. The SUB 200T is the 39mm 18mm watch; the SUB 200 is the 42mm 19mm watch; the SUB 200 II is the 44mm 20mm watch; the SUB 200 T.GRAPH II is the 42mm 20mm chronograph [7] [1] [9] [13]. The T is not a size marker, the II is not a colorway, and none of the four share a strap. The same discipline applies across the range: SUB 300 and SUB 300T share 20mm [15] [17], but the 300T of 2002 shares nothing, and the earlier versus current SUB 600T both take 20mm despite different cases [3] [18]. When in doubt, the SKU on your warranty card resolves the family, and DOXA's product pages carry a printed Lug width line for each [1] [18].

Your Doxa is not in the table

Then measure, and treat the case size as a hint rather than an answer. Pop a spring bar and measure the gap in millimeters as the measuring guide shows; the lug width chart places DOXA's 18 to 21mm spread against every other brand's. Two DOXA-specific rules before you search elsewhere: a golden-dial or special edition almost always shares its family's case, so the base model's row applies, and if a listing disagrees with DOXA's own Lug width line, the listing is the one that is wrong. The band size chart hub carries the full brand index, and the NATO strap length guide covers the second decision, length, once the width is settled.
