Apple 42mm Olive Sport Band M/L — Soft, Durable Band for Apple Watch
42mm band groupSize M/LOlivePin-and-tuck closure
The Apple 42mm Olive Sport Band in size M/L (MJVA4ZM/A) is Apple's own rubber band for Apple Watch, made from a custom high-performance compound that is durable and strong yet soft against the skin, with a pin-and-tuck closure that sits flush. It suits everyday wear, the gym and running, and the olive colour matches both aluminium and titanium cases.
This is the 42mm band group, which fits 38mm, 40mm, 41mm and the new 42mm Apple Watch cases (Series 10 and later). The M/L size is for medium to larger wrists; Apple also makes the same band in S/M.
Before you order: "42mm" here means the new 42mm case (Series 10 and later). If you own an older 42mm Apple Watch (Series 1, 2 or 3), it uses the larger band group — you need a 46mm band, not this one.
What's in the Box
- 1 × Apple 42mm Olive Sport Band, size M/L
What It Means in Practice
- Swaps on in seconds with Apple's band release button — no tools.
- Rubber is sweat- and water-friendly, so it is the band to wear for workouts and swimming.
- Pin-and-tuck closure keeps the loose end inside the band so it does not catch on sleeves.
- If you are between sizes, M/L fits medium to larger wrists; for a smaller wrist choose the S/M version.
What Will Not Work
- 44mm, 45mm, 46mm and 49mm (Ultra) cases — those use the larger band group.
- Old 42mm cases from Series 1, 2 and 3 — they need a 46mm-group band.
- Non-Apple smartwatches or watches with standard spring bars.

Frequently Asked Questions
Will it fit my Apple Watch SE 40mm?
Yes. The 42mm band group fits 38, 40, 41 and new 42mm cases, including SE 40mm.
Which size, S/M or M/L?
M/L is for medium to larger wrists. If you usually wear watches on the tighter holes, S/M is the better choice.
Can I swim with it?
Yes — the Sport Band is made of rubber and is the band Apple designs for workouts and water.
Singular Expert Insight · Buyer's Guide
Apple's band sizing trips people up because "42mm" now means two different watches. Check the case size engraved on the back of the watch: 38–42mm (new) takes this band, 44mm and up does not. More straps are in our
phone and watch accessories.
✓ Buy it if your Apple Watch case is 38, 40, 41 or the new 42mm and you want a durable everyday and sports band.
✕ Skip it if your watch is 44mm or larger, or an older 42mm Series 1–3.
→ Also consider the same Sport Band in S/M, or a Sport Loop for an adjustable hook-and-loop fit.
Not sure which band size your watch takes? Send us the model or the case size on the back and we will check before you order.
