49mm Natural Titanium Milanese Loop - Medium

I understand you're interested about the weight of the 49mm Natural Titanium Milanese Loop across all sizes. Unfortunately, specific weight details for each size—Small, Medium, and Large—aren't readily available, AFAIK, from Apple's official specifications or other reputable sources.

For the "why" you need to ask Apple. Otherwise, purchase it and weight it yourself.
