Silicone straps for everyday wear and exercise
Silicone is the everyday strap. It is soft, waterproof and easy to wash, which makes it the one most people wear to the gym, in the pool and in bed. It stays put on a sweaty wrist and does not mind the rain. The straps here are made to be compatible with Apple Watch, not by Apple, and slide into the watch's band slots in the usual way.
What the silicone straps here are like
The silicone straps filed here are sport bands for the larger Apple Watch group, from the 42mm Series 3 and earlier to the 44mm, 45mm and 46mm Series models and the 49mm Ultra. They have grooves along the strap to let air reach the skin and cut down on sweat, and a curved end that sits close to the watch. The metal connectors come in a choice of finish, picked along with the colour, so the hardware can match a titanium-coloured or a black watch case.
For the smaller group, 38mm to 42mm, the silicone straps with air holes in magnetic watch straps come in both size groups, closing with a magnet in place of a pin and tuck. For a Galaxy Watch, see the silicone straps in Galaxy Watch straps.
Getting the size and the fit right
Apple sorts its watch sizes into two groups, and a strap made for one size fits every size in its group. Bands for 38mm, 40mm, 41mm and 42mm fit 38mm, 40mm, 41mm and 42mm cases. Bands for 44mm, 45mm, 46mm and 49mm fit 44mm, 45mm, 46mm and 49mm cases. Your watch's size is engraved on its back. There is one trap: on the old Series 3, 42mm was the larger of the two cases, so a 42mm Series 3 takes straps from the larger group.
The sport band here is made for that larger group. Once it is on, wear it snug but comfortable, as Apple puts it: close enough for the sensors on the back to stay against your skin, loose enough to leave no deep marks. Apple says a strap that is too tight can irritate the skin. Wrists swell a little after a run or on a hot day, so a strap that is right in the morning may want loosening by the afternoon.
Looking after a silicone strap
Apple says its sport bands can be washed with a mild, hypoallergenic hand soap. Rinse a strap in fresh water after the sea or a pool, and dry the strap and your wrist before you put it back on. Silicone can pick up lint and feel warm in hot weather; the grooves help with the heat. Replace a strap when it splits or cracks, especially round the holes, because a strap that fails is how a watch ends up on the pavement.
Questions people ask about silicone watch straps
Can I swim in a silicone strap?
Yes. Silicone is made for water. Rinse it in fresh water afterwards and let it dry.
Will this strap fit my 41mm Series 9?
No. 41mm is in Apple's smaller group, and the sport band here is for the larger one. Look at the magnetic silicone straps, which come in both groups.
