Apple 42mm Navy Magnetic Link S/M — FineWoven Band with Flexible Magnetic Closure
42mm band groupSize S/MNavyFineWoven · magnetic
The Apple 42mm Navy Magnetic Link in size S/M (MGDA4ZM/A) is Apple's own dressier band for Apple Watch, made from FineWoven — a durable microtwill with a soft, suede-like feel — with molded magnets that gently flex and hold the band closed at any length. It suits office and evening wear rather than the gym.
The material is made with 95% recycled polyester and the magnets with 100% recycled rare earth elements. This is the 42mm band group: it fits 38mm, 40mm, 41mm and the new 42mm Apple Watch cases (Series 10 and later). S/M is for smaller to medium wrists.
Before you order: "42mm" means the new 42mm case (Series 10 and later). Older 42mm watches (Series 1–3) need a 46mm-group band. The band is not water resistant — take it off for workouts in water and swimming.
What's in the Box
- 1 × Apple 42mm Navy Magnetic Link, size S/M
What It Means in Practice
- Magnetic closure adjusts to any position, so the fit is continuous rather than hole-by-hole.
- Soft fabric feel for all-day office wear; switch to a Sport Band for workouts.
- Swaps on with Apple's band release button, no tools needed.
- The magnets can affect the Compass app reading on the watch, as Apple notes.
What Will Not Work
- 44mm, 45mm, 46mm and 49mm (Ultra) cases, or old 42mm Series 1–3.
- Swimming, showering or water sports — the band is not water resistant.
- Non-Apple smartwatches.

Frequently Asked Questions
Will the magnets affect my watch?
Apple notes they may interfere with the Compass app; other functions are not affected.
S/M or M/L?
S/M suits smaller to medium wrists. Because the magnetic closure adjusts continuously, the size range is generous within each size.
Can I wear it in the rain?
Light splashes are fine, but the band is not water resistant — avoid swimming and showers.
Singular Expert Insight · Buyer's Guide
The Magnetic Link is the band to pick when the watch is part of a work outfit: fabric feel, no buckle, and quick to adjust. Check the case size on the back of the watch first — 38–42mm (new) only. More straps are in our
phone and watch accessories.
✓ Buy it if your Apple Watch is 38, 40, 41 or the new 42mm and you want a soft, office-friendly band with an easy magnetic fit.
✕ Skip it if you swim or train in water with the watch, or your case is 44mm or larger.
→ Also consider the same band in M/L, or an Apple Sport Band for workouts.
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.
