Apple Watch 42 / 44 / 45 / 46 / 49 mm (larger)

Apple Watch accessories — larger case

Apple Watch in 42-49 mm sizes is the larger case version, ranging from Series 4 (44 mm) to Series 10 (46 mm) and Apple Watch Ultra (49 mm). The strap attachment is compatible within this group, so a strap for the Series 7 45 mm will also work with the Series 10 46 mm.

Strap compatibility

Straps for larger Apple Watch sizes are interchangeable between the following models:

• 42 mm — Series 1, 2, 3
• 44 mm — Series 4, 5, 6, SE (1st gen.)
• 45 mm — Series 7, 8, 9, SE (2nd gen.)
• 46 mm — Series 10
• 49 mm — Ultra 1, Ultra 2

All these sizes use the same attachment system. The difference only concerns cases and screen protectors, which must match the specific case size.

Accessory types

• Silicone straps — sporty, waterproof, in dozens of colours
• Fabric straps — nylon and braided, breathable and light
• Metal bracelets — mesh and link, an elegant look
• Protective cases — bumpers that protect the watch case from impacts
• Tempered glass and films — protect the screen from scratches

What to look out for

Straps are universal within the "larger case" group, but cases and glass must match the size — a 44 mm case will not fit a 45 mm watch. When buying, check the exact size of your Apple Watch (Settings > General > About on the watch).

FAQ

Does an Apple Watch Series 7 (45 mm) strap fit the Series 10 (46 mm)?

Yes — all straps in the larger case group (42-49 mm) are compatible with each other thanks to an identical attachment system.

Does an Apple Watch 44 mm case fit the 45 mm?

No — the 44 mm (Series 4-6) and 45 mm (Series 7-9) cases differ in dimensions. Cases and glass must be matched to the specific size.
