Boccia band size chart: 23 references tabled verbatim by catalogue number, from a 14mm ladies watch to one 25mm tank

Boccia is the German brand that sells nothing but solid titanium watches, buckles included, and keys its entire catalogue by four-digit reference numbers in the 3xxx-xx form. The strap width, when the brand states it at all, lives inside the product copy of exactly 23 of the 261 watch references in the boccia.com merchant feed ^[24]^[26]. This chart tables those 23 rows word for word, keyed by reference number, and leaves the other 238 pinned as not printed rather than guessed.

Quick answer: the tabled references split across six widths. 14mm on the 3314 ladies pair, 16mm on the 3315 and 3316 pairs, 18mm on the 3309, 3335 and 3356 classes, 20mm on the mens 3615, 3620, 3662, 3664 and 3749 references, 22mm on the 3745 pair, and a single 25mm strap on the 3147-04 tank ^[1] ^[3]. If your reference is not in the table, the brand's own page prints no width for it anywhere: measure the lug gap before ordering.

What the reference number does and does not decode

The first four digits group the catalogue into families: the 31xx to 33xx block carries the ladies, midsize, unisex and kids watches, and the 35xx to 37xx block the mens three-handers and chronographs, including the big id. series at 3535 with 63 references and 3777 with 29 ^[24]. But the prefix is not a width decoder, and this chart never treats it as one: inside the same 31xx to 33xx block the 3314 prints 14mm while the 3147 prints 25mm ^[1]^[23]. Only the 23 tabled references carry a first-party printed width; every other number in the catalogue is unpinned by the brand's own pages.

The wording varies row to row, which is why the table quotes each line instead of summarizing it. The dominant form is Strap width: 20mm after the case line, as on the 3662 ^[16]. The 3356 ladies trio states it the other way round, Case Size: 35mm width, 9mm thickness 18mm strap width ^[10]. The 3335-02 unisex calls the same measurement lugs: Case Size: 34mm width, 6.5mm thickness, 18mm lugs ^[9]. The 3745 pair introduces a fourth label, Measurements: 41mm width, 11mm thickness. 22mm strap width. ^[21]. And the 3620-08 prints no case label at all, just 39mm wide 8.1mm thick 20mm strap width in one run ^[15]. Same measurement, four spellings, one table.

The 25mm tank: the 3147-04

One tabled reference breaks the small-watch pattern: the 3147-04, a discontinued final-sale midsize whose own line reads Case: 24mm wide x 28mm long Strap Width: 25mm wide ^[23]. It is a rectangular titanium tank watch, white dial, on what the brand calls a wide white strap, and it is both the smallest case in the table and the widest strap in it. The 25mm figure is printed by the brand itself, which is the only reason it is here; no other Boccia in the feed prints anything above 22mm.

One bookkeeping quirk worth knowing: the 3316-04 lists as Midsize Boccia Titanium Watch in its title while its own URL handle says ladies ^[6]. The spec text is identical to the 3316-01 either way, Case Size: 36mm width, 7.5mm thickness Strap width: 16mm, so the width answer does not turn on the label.

Coverage: what this page is and is not

This is a partial-coverage chart and the basis is stated exactly. The boccia.com merchant feed was pulled fresh at build time, products.json at limit 250: page 1 carries 250 products, page 2 carries 250, page 3 carries 184, and page 4 comes back empty, so the catalogue window is complete at 684 products ^[24]^[25]^[26]^[27]. Of those 684 rows, 261 carry a 3xxx-xx watch reference number in the title; the remainder are the jewellery and accessory side of the catalogue, rings, earrings, bracelets, necklaces, pendants, cufflinks and chains, plus shop rows like personalization and membership that carry no watch specs at all. Exactly 23 of the 261 watch references print a strap width phrase in the product copy: 22 on feed page 1 and 1 on page 3 ^[24]^[26]. The other 238 print nothing at the lugs, and this chart does not backfill them from siblings, because the 3147-04 is proof that a guessed width inside the 31xx block can be wrong by 11mm.

Three of the 23 tabled references were re-checked against the fully rendered product pages, not just the feed JSON, with a desktop browser profile: the 3662-03, the 3147-04 and the 3316-01 all print the identical width phrase on the rendered page ^[17]^[23]^[5]. Every quote in the table is a contiguous substring of the product copy as pulled, never normalized, never re-punctuated. No prices appear on this page because the feed carries bare subunit integers with no currency-coded rail.

No consolidated Boccia width chart exists at build time. The brand prints one watch at a time and never tabulates; search returns generic how-to-measure guides with no Boccia-specific data; and the watchbands.ai brand index, 193 slugs at the fresh pull, carries no Boccia entry by either slug or text match ^[28]. WristFit is an independent reference, not affiliated with Boccia or any watch brand.

Frequently asked questions

What size strap does a Boccia 3662 take?

20mm. Both tabled references print it the same way: Case: 37mm, 7mm Thickness Strap width: 20mm, on the 3662-01 and the 3662-03. The whole mens three-hand class tabled here agrees: 3615 and 3620 and 3664 and 3749 all print 20mm.

What size strap do the Boccia ladies watches take?

The tabled ladies references split 14, 16 and 18mm by reference number: the 3314 pair prints Case Size: 32mm width, 6mm thickness Strap width: 14mm, the 3315 pair prints 16mm on the same 32mm case, the 3316 midsize pair prints 16mm on a 36mm case, the 3309 pair prints 18mm, and the 3356 trio prints Case Size: 35mm width, 9mm thickness 18mm strap width. The 3335-02 unisex prints 18mm lugs.

What is the smallest Boccia strap width?

14mm, on the 3314-02 and 3314-03 ladies references, quoted as Case Size: 32mm width, 6mm thickness Strap width: 14mm. Nothing else in the tabled set goes below 16mm.

Why does one Boccia take a 25mm strap?

The 3147-04 is a discontinued tank-style watch whose own line reads Case: 24mm wide x 28mm long Strap Width: 25mm wide. It is the widest strap in the tabled set on the smallest case, a rectangular fashion watch on a wide white strap, and it is the only tabled reference above 22mm.

Is there an official Boccia band size chart?

No. The brand prints a strap width inside the product copy of 23 of its 261 watch references and never tabulates them. Search returns generic how-to-measure guides with no Boccia data, and the watchbands.ai brand index carries no Boccia entry. This chart is the first place the printed 23 sit in one table.

My Boccia reference is not in the table. What size is it?

Not printed anywhere on the brand's own page, so this chart refuses to guess. The 238 watch references outside the table carry no width phrase in their product copy, and sibling references are not a safe backfill: the 3147-04 proves the 31xx block can hide a 25mm. Measure the lug gap between the spring bars before ordering.
