FAQ

Quick answers before you buy

Will this fit my Apple Watch?
Yes — as long as you pick the right size. Choose by your watch's case size: 38, 40 or 41mm straps fit the smaller watches; 42, 44, 45 and 49mm fit the larger ones. Between them they cover Apple Watch Series 1–10, SE (1st & 2nd gen), and Ultra / Ultra 2. The strap clicks into the same slots as your original Apple band.
How do I know which size I have?
Check the back of your watch or your original Apple packaging — the case size (e.g. "45mm") is printed there. You can also open the Apple Watch app on your iPhone → General → About → Model. If you're between sizes or unsure, email us before ordering and we'll confirm.
Is the buckle really stainless steel?
Yes. The clasp and keeper are brushed stainless steel, not plated plastic. It's a noticeably more solid, premium feel than the plastic pin closures used on most budget silicone bands.
Can I wear it for workouts, showers and swimming?
Absolutely. The silicone is water-resistant and sweat-proof, so it's fine for the gym, the shower and the pool. Rinse with fresh water after swimming in chlorine or salt water and wipe dry — that's all the care it needs.
How is it different from a £49 official Apple band?
You're paying for materials and feel, not a logo. You get soft-touch silicone and a real stainless steel buckle at £19.99 — roughly the price of one Apple band, for a look and comfort that's close to it. The main trade-off is the brand name on the box, not what's on your wrist.
How long does delivery take?
This band ships direct from our supplier, so standard delivery typically takes around 7–10 days. You'll get a confirmation email when your order is on its way. If you need it sooner, contact us first and we'll let you know what's possible.
What if it doesn't fit or I change my mind?
No problem — you can return it within 30 days, unused and in its original packaging, for a refund or exchange. Start your return through our returns portal, or email hello@casemonkey.co.uk and we'll help.
