This Apple knowledge base page (via 512 Pixels) has beautifully detailed pictures of each Apple Watch band style, along with instructions on properly fastening each band type, as well as tips on getting the best fit.
What I found fascinating about the page was the pair of warnings at the bottom:
Apple Watch, the space gray and rose gold aluminum Apple Watch Sport, the stainless steel portions of some Apple Watch bands, and the magnets in the watch and bands contain some nickel. However, they all fall below the strict nickel restrictions set by European REACh regulation. Therefore, while nickel exposure is unlikely to be a problem, you should be aware of the possibility in case you’re susceptible to nickel-related reactions.
And:
The Apple Watch case, the Milanese Loop, Modern Buckle, and Leather Loop bands contain trace amounts of methacrylates from adhesives. Methacrylates are commonly found in many consumer products that come in contact with the skin, including adhesive bandages, but some people may be sensitive to them, or develop sensitivities over time. Methacrylate exposure from Apple Watch and the bands listed above is unlikely, but customers with known methacrylate allergies should be attentive when wearing the bands until they can determine they are not experiencing an allergic reaction.
The page was published last September, so this is likely old news, but this is the first time I’ve encountered these warnings.
It’s a nicely put together page, but honestly if you can’t figure out how to fasten a watch band, and there is nothing unique or special about how the Apple Watch bands fasten, then a smart watch really isn’t for you.
I have a Milanese Loop band. I would love to know how to fasten it better. Sadly, this page contained no additional insights.
…it tends to get looser over the day as I move.
i agree this is somewhat idiotic.
There really isn’t a way to fasten it better (I happen to be wearing mine today). The beauty of the Milanese loop is that it can adjust to any size. However, since it only fastens via magnet, without a positive latch, it can loosen slightly throughout the day as you move your wrist, catch the watch on pockets and sleeves, and even expand and contract with water weight. It only takes a second to tighten it back up if it becomes a bit too loose.
FWIW, my wife got a knock off Milanese loop from Amazon because she wanted Rose Gold. The magnet isn’t nearly as strong at the one on the Apple band, and hers loosens far more frequently than mine. I generally find mine will go most of the day without needing any tightening, and the magnet is very strong.
I think mine might have a weaker than average magnet. I’ve thought about doing something, but the little tug every three hours or so has just become part of my routine and is something I no longer notice.
Had my black loop for 10 days – it’s lovely BUT it does slip loose quite easily during normal everyday wearing
