Just an FYI in case anyone has a broken screen on their 7X. 7X parts have been very rare on eBay since the release of the 7 series, so I was surprised to see this screen assembly just come up:

It seems like a decent price all things considered, so I thought I would pass it along. I'm not really sure how long the 7X has been out, so it's certainly possible that all 7 series watches are still within warranty from Garmin, but I would expect to start seeing a lot more parts become available on eBay and AliExpress as the oldest watches begin to reach their EoW.
