The 42mm case was introduced with Apple Watch Series 10 in 2024, a slimmer, thinner redesign of the smaller Apple Watch size, and carried through Series 11 and the new Series 12, including the ceramic Series 12 models. Bands sized "40/41/42" fit this case, so the full OzStraps Apple Watch range is compatible. The best-selling Silicone Apple Watch Band leads the range, alongside the Black Milanese Loop and a full spread of sport, steel, leather and nylon styles. Everything ships fast from Australian stock with a 12-month local warranty and a satisfaction guarantee.
Which Watches Use the 42mm Case?
The 42mm case is the smaller of the two current Apple Watch sizes, used on Series 10, Series 11 and Series 12 (the larger being 46mm). All three share the same band connector, so any band sized "40/41/42" fits any of them, and bands from an older 38mm, 40mm or 41mm Apple Watch carry over too. One important note: this is not the same as the original 42mm case used on Series 1, 2 and 3, which takes the larger "44/45/46/49" band size instead. If your watch is a Series 3 or earlier, head to the 42mm Series 1, 2, 3 collection. For details specific to your exact model, see the Series 11 or Series 12 pages, and the Apple Watch Band Compatibility Guide covers sizing across every series.

Frequently Asked Questions
How do I know if my Apple Watch is 42mm?
Check the back of your watch case for the size printed there, or measure the case width edge to edge. The 42mm case is used on Series 10, 11 and 12, alongside a larger 46mm option.
Do 42mm bands fit all three series?
Yes. Series 10, 11 and 12 all share the same 42mm case and band connector, so bands sized "40/41/42" are fully interchangeable across all three, including the ceramic Series 12 models.
My Apple Watch Series 1, 2 or 3 is also 42mm. Are these the same bands?
No. The original 42mm case on Series 1, 2 and 3 takes the larger "44/45/46/49" band size, not "40/41/42". The 42mm Series 1, 2, 3 collection has the right fit for those older watches.
Will bands from my old 38mm, 40mm or 41mm Apple Watch fit?
Yes. The band connector hasn't changed, so bands from any smaller-case Apple Watch fit the 42mm Series 10, 11 and 12. Bands sized "40/41/42" cover this whole family.
How do I change the band on my Apple Watch?
Press the small release button on the back of the watch case, slide the old band out, then slide the new band in until it clicks securely into place. No tools are required, and the band-changing guide shows each step.
