Mine arrived with dead battery. 3 days in full sun still isn't on hi. lithium-ion shouldn't be kept long term at 0%. will mine never go to hi??

Yes it wil get to high. Sometimes it can take up to 7 to 10 days in direct sunlight. I have 9 solar atomic gshocks. And l had the same problem with one it took 5 days in outside sunlight. I live in Florida with plenty of Sunshine. Believe it will charge high.

Can anyone tell me if these are legit or if they are fake?

I bought my Mudmaster G-Shock from Amazon this year (2020) and it's legit too. I was initially worried about the same issue and I'm pleased to say it wasn't a problem at all.

does the gw6900-1 have the auto-calendar function?

Yes. The calendar updates automatically with the time each night when it syncs with the atomic signal. Is that what you meant? In other words, the watch has never been on the wrong date since the day I bought it. And I have two of these that work perfectly.

Does the watch have a button for the light?

The watch has an auto illumination feature where when you tilt the watch toward you the face illuminates. However, I am not aware of a manual button to turn on the light. You might want to go online and find the users guide and examined it.
