Apple Milanese Loop not secure

Look closely at the part of the band which attaches to the watch body, and compare the two parts. You should be able to see the locking tab and compare its movement. If the problem end looks to have all its parts try a rinse in warm water to clear any deposits which may have accumulated in the mechanism.

The magnetic piece should lock on any side. I have the Milanese band and it works fine.

Thank you for the clarification. Sounds like you have a defective band.

Not seeing a difference is good, it means nothing has broken off. Hot scrub was the correct next step... because it worked.
