A 44mm metal Milanese loop band is compatible with Apple Watch cases that use the 44mm lug width, which also matches the 42mm (Series 1–3) and 45mm case families. In practical terms, that means a 44mm Milanese loop will fit these case sizes: 42mm, 44mm, and 45mm.
Apple groups watch cases into two connector families: the smaller sizes (38/40/41mm) and the larger sizes (42/44/45mm). If your watch is in the larger group, the 44mm band will slide in and lock normally. If your watch is in the smaller group, it won’t align correctly with the lugs and should not be used.
42mm (Apple Watch Series 1, Series 2, Series 3)
44mm (Apple Watch Series 4, Series 5, Series 6, Apple Watch SE)
45mm (Apple Watch Series 7, Series 8, Series 9, Apple Watch Ultra/Ultra 2 adapters typically require Ultra-specific sizing, but 45mm shares the “large” connector family)
38mm, 40mm, 41mm cases use the smaller connector family. A 44mm Milanese loop won’t seat properly and can compromise security and comfort.
Check the engraving on the back of the Apple Watch case (it lists the case size in millimeters) or verify the model in the Watch app on iPhone. Match it to the larger connector group (42/44/45mm) for a 44mm Milanese loop.

For 44mm Milanese Loop Compatibility: 42/44/45mm Cases, the best answer depends on fit, material, care instructions, and how the product will be used day to day.
Yes. The 44mm and 45mm cases share the same larger band connector family, so a 44mm Milanese loop is designed to fit securely on a 45mm Apple Watch.
