Pompeak band size chart: the one British brand whose flagship is the odd 21mm

Pompeak is a Bristol microbrand run by two brothers, and its strap widths do something almost nobody does on purpose: the flagship Gentlemen's Classic line sits on 21mm lugs while everything before and after it sits on 20 or 22 ^[24]. Every watch row in the pompeak.com merchant feed carries an explicit Strap line in its technical block, all 23 of them, and this chart tables those lines word for word: five Gentlemen's Classic references at 21mm, six Mallory and four Sub-Aquatic references at 20mm, and eight 45mm chronographs at 22mm ^[1][12][17].

The chart: 23 watches, three widths, every spec line verbatim

n/p means the feed row prints no lug-to-lug figure for that reference. The spec text column quotes the technical block of each product page exactly as the feed serves it, with tags stripped and spacing normalized; nothing is re-punctuated or re-parsed. Where a collection shares one spec line, every reference still gets its own row and its own citation, because the feed prints the line per product.

The 21mm flagship: why the Gentlemen's Classic is the trap

Odd widths are the classic trap in this trade, and Pompeak built one into its own flagship. The Gentlemen's Classic is a 40mm case, and the reflex move on a 40mm case is a 20mm strap; the spec block says otherwise: Technical Case Material 316L Stainless Steel Strap 21 mm Linked Stainless Steel - Silver Movement Miyota 82S5 (Automatic) Size 40 mm Case Diameter 10.4 mm Thickness ^[3]. All five current references agree, Black, Navy, Sky Blue, Wonky Panda and British Racing Green ^{[1][2][3][4][5]}, and the brand's own accessory line follows: 21mm Straps, a choice of 21mm top grain leather straps, each fitted with butterfly deployment clasps, Designed to be used with any watch from the Gentlemen's collection ^[26]. Independent reviewers noticed the same thing, one writing of the bracelet that it is 21mm wide at the lugs, and so your choice of replacement straps will be limited, adding they were not sure why Pompeak chose not to go for 20mm or 22mm ^[34]. Nobody charting widths had collected these lines in one place before this page.

The 20mm and 22mm pools are the cleanest possible counterpoint. The Mallory dress watches, also 40mm cases, print Strap 20 mm Top Grain Leather / Milanese Mesh on every reference ^[6], and the Sub-Aquatic divers, 40mm again, print Strap 20 mm with no strap-type suffix at all because the stock fitment is the bracelet question the accessory page answers ^[13]. So three 40mm collections ship on two different widths, 20 and 21, and case size tells you nothing. Collection does.

The 22mm chronographs and the 904L bracelet exception

The eight chronographs are the easy half of the catalog: every one prints Strap 22 mm in a Brushed 316L case at Size 45 mm, split between Linked Stainless Steel in Silver or Black and Interchangeable Genuine Leather in Tan, Black or Burgandy, the last being the Rose Gold pairing and the brand's own spelling ^{[17][18][19][20][21][22][23]}. One fitment rule inside the 20mm pool is worth more than the whole width table: the brand's 20mm Straps page states the 904L Stainless Steel Bracelet is designed to be used with our Sub-Aquatic watches, while All others will fit any watch with 20mm lugs (Sub-Aquatic or Mallory Collections) ^[27]. Shared width does not mean shared end links, and the Mallory buyer who orders the 904L bracelet on width alone is the second trap this catalog sets.

The Debut Collection: discontinued, and why it is not tabled

Pompeak's first watch, the Debut Collection, a minimal quartz timepiece per the launch-era reviews, no longer exists in the pompeak.com catalog: not one of the 37 product rows in the current feed is a Debut watch ^[24][32]. The only surviving first-party trace of it is accidental and useful: the 22mm Straps accessory page still reads To be used with our watches from our Debut collection, which pins the Debut lug width at 22mm from the brand's own store even though the watches are gone ^[28]. If you own a Debut watch, that strap page, not a 20mm assumption, is your rail.

Coverage: what this page is and is not

The basis is exact. The pompeak.com merchant feed was pulled fresh at build time, products.json at limit 250: page 1 carries all 37 products and page 2 comes back empty, so the catalog window is complete ^[24][25]. Of the 37 rows, 23 are watches and every one prints an explicit Strap line; 6 are strap accessories (the 20mm, 21mm and 22mm collections and three 20mm NATOs), and 8 are non-watch gear (rolls, pouch, gift card, t-shirt, spring bar tool) that carries no width. Two spec blocks were re-verified against the fully rendered product pages, not just the feed JSON, with a desktop browser profile: the Gentlemen's Classic Black page renders its technical block, including 40 mm Case Diameter, server-side, and so does the Mallory Arabic Cherry page, whose block continues 48 mm Lug to Lug 12.6 mm Thickness (Including glass) ^[29][30]. Every quote in the table is a contiguous substring of the product copy as pulled.

No consolidated Pompeak width chart exists elsewhere at build time. The brand prints one watch at a time and never tabulates; the watchbands.ai brand index, 193 slugs at the fresh pull, carries no Pompeak entry by slug or text ^[31]; and the per-model spec databases that do list individual Pompeak watches, one lug-to-lug and pricing reference for the Sub-Aquatic, another for the Gentlemen's Classic and the Mallory, publish model pages rather than a brand chart ^[33][35]. WristFit is an independent reference, not affiliated with Pompeak or any watch brand.

Frequently asked questions

What size strap does a Pompeak Gentlemen's Classic take?

21mm. Every Gentlemen's Classic in the current catalog prints the same line, Strap 21 mm Linked Stainless Steel - Silver: Black, Navy, Sky Blue, Wonky Panda and British Racing Green. The brand's own strap shop sells the matching width under 21mm Straps, described as Designed to be used with any watch from the Gentlemen's collection. A 20mm strap bought on the assumption that a 40mm case means 20mm lugs will be wrong by a millimetre at both spring bars.

What size strap does a Pompeak Mallory take?

20mm. All six tabled Mallory references print Strap 20 mm Top Grain Leather / Milanese Mesh, and the brand's 20mm Straps page states the fit rule outright: All others will fit any watch with 20mm lugs (Sub-Aquatic or Mallory Collections).

What size strap does a Pompeak Sub-Aquatic take?

20mm. All four editions, Red & Black, Night, Waffle and Deep Dive Dial, print Strap 20 mm with a Sellita SW200-1 Swiss automatic in a 40mm 904L steel case. One caution from the brand's own accessory page: the 904L Stainless Steel Bracelet in the 20mm Straps collection is designed to be used with the Sub-Aquatic watches specifically, so it is not a universal Mallory fit despite the shared width.

What size strap do the Pompeak chronographs take?

22mm. All eight 45mm chronograph references print Strap 22 mm: Silver Night and Silver Sky on Linked Stainless Steel - Silver, Metallic Black and White Night on Linked Stainless Steel - Black, and Leather Black, Silver Tan, Rose Gold and White Light on Interchangeable Genuine Leather.

Is there an official Pompeak band size chart?

No. The brand prints the width one product at a time in a technical spec block and organizes its accessory store as 20mm Straps, 21mm Straps and 22mm Straps collections, but never tabulates which watch takes which. No third-party chart exists either: the watchbands.ai brand index carries no Pompeak entry, and the per-model spec databases that list individual Pompeak watches do not consolidate them.

My Pompeak is from the Debut Collection. What size strap?

22mm, per the brand's own 22mm Straps page, which still reads To be used with our watches from our Debut collection. The Debut Collection itself, the Kickstarter-era quartz line, no longer appears in the pompeak.com catalog, so this page cannot table it from the current feed; only the surviving 22mm strap listing confirms the width.
