Sense defective cable design.

Always the same pin OEM or aftermarket. I no longer allow the magnet to snap pins in place and they still fail.  I now order two-packs in anticipation of it breaking for no conceivable reason.

The below image represents only the most recent orders that would fit on my screen.  There have been mounted charging stations as well and they fail in the exact same way.

I've purchased enough chargers to equivocate the purchase price of the original device.

Hi @Puddlewiggle - while this cable design is s common problem for some there may be some conditions that make it worse.

For instance if you plug the cable in before adding the watch.

I have the same cable since over 3 years and always connect the cable first before plugging it in to charge and unplug it before removing the watch from the cable, admittedly I only charge about once a week so may make less interactions than people who charge daily.

Of course there can be tolerances in manufacturing that means the contacts are not making good contact but this can also be due to lack of cleaning as the holes can collect dirt and cleaning before each charge is important.

Lastly try using a different power source in case a particular one is causing a problem but that seems unlikely.
