Apple Watch Series 5 40mm Band, Protection & Accessories

For the Apple Watch Series 5 40mm (40mm), six band types matter most. The Sport Band is fluoroelastomer — soft, sweat-resistant, ideal for training. The Sport Loop is woven nylon with hook-and-loop closure — breathable and quick to adjust. The Solo Loop is seamless silicone in a fixed size — no buckle. Leather looks elegant at the office and develops patina over time. The Milanese loop is magnetic stainless mesh — infinitely adjustable and elegant. The stainless-steel link bracelet is the most rugged choice. Pick by occasion: sport (Sport Band or Loop), everyday (Solo Loop), office (leather or Milanese), formal (link bracelet).

Three protection types are common. PET film is the cheapest, decent against everyday scratches but thin. Hydrogel film is flexible and conforms to Apple Watch''s curved glass right to the edges — ideal, since the glass is not flat. Tempered glass offers the strongest scratch and impact protection but can lift at the edges on heavily curved models. Look for full-cover variants that protect the whole front face, or display-only films. For the Apple Watch Series 5 40mm we recommend hydrogel or a full-cover bumper with integrated protection.

A bumper case wraps the rim of the aluminium or stainless steel case and absorbs impacts — important for sport, cycling, climbing or manual work, where the case can hit door frames, tools or table edges. Wrap-around cases additionally protect the display with an integrated glass or plastic layer — a 2-in-1 of bumper and screen protector. Make sure the case leaves the Digital Crown and side button free, otherwise you cannot operate them properly.

The Apple Watch charges via a magnetic charger — Apple''s watch-specific “MagSafe for the watch”. Genuine Apple chargers and compatible third-party cables come with USB-C or USB-A on the other end. For travel there are compact power-bank chargers with a built-in watch puck and travel sets with combined iPhone+Watch charging. Fast charging (up to 80 % in about 45 minutes) works from Series 7 onward with the included USB-C fast-charge cable and a USB-C power-delivery adapter of 18 W or more. Older chargers charge more slowly.

The Apple Watch Series 5 40mm has a 40mm case, shared with Series 4, 5, 6, SE 1 and SE 2. All 40mm bands fit. The newer 42mm format arrived only with Series 10 — those newer bands clip on with some play but don''t always sit perfectly. For best fit pick a band labelled 40mm-compatible.

Which band size fits my Apple Watch?

What matters is the case size, not the series number. The Apple Watch Series 5 40mm needs 40mm bands. They also fit Series 4, 5, 6 and SE/SE 2 (40mm).

Apple''s own bands offer the highest material and build quality, full magnetic compatibility and a perfect fit. Premium third-party brands (Spigen, Nomad, UAG, Pitaka) are often noticeably cheaper and come in more designs — quality gets very close. For sport, third-party bands are more than enough, for office and formal wear, many customers still pick Apple''s Milanese or leather band.

Press the small button on the back of the watch (band release) and slide the band out of the rail sideways. Push the new band into the same rail until it clicks. Make sure both halves of the band (top and bottom) are seated. It takes seconds and needs no tools.

A bumper case wraps the case rim and absorbs side impacts — it mainly protects the edge. For the screen itself we additionally recommend a hydrogel film or tempered glass. Wrap-around cases combine both: a bumper at the rim plus an integrated screen protector.

Fast charging is supported from Apple Watch Series 7 onward (up to 80 % in about 45 minutes). You need an Apple USB-C fast-charge cable and a USB-C power-delivery adapter of 18 W or more. The cable in the box supports fast charging — older USB-A watch chargers do not. Apple Watch Ultra, Ultra 2 and Series 8/9/10/11 also benefit from the fast-charge cable.
