Garbage
Color: Black/Black/Digital Neg Display
Absolute garbage. The date that came up was from 2022. Most buttons did not work. Once you got into changing the time, etc, the watch locked up and would not get out of 'timer' mode. The watch lost 10 minutes in three hours. Do not purchase.

Great Watch
Color: Red
Beautiful and is well made. Because it's multi colored it matches everything.

Cheap buckle and band. Did not last one day
Color: Blue
Why did you pick this product vs others?:
Watch buckle is made of plastic that looks like metal. The watch band broke off the watch face 1 hour into my 12 hour shift. It LOOKS really cool. Love the Boho look, but the quality of the watch band and buckle are very cheap and not at all durable.

I ordered a magnetic band.

Great watch while it works but durability is questionable.
Color: Green
Cute, fun watch that keeps good time but band fell off the first week I wore it. A kind passer-by returned it to me. I got the band back on and it's been fine since but would have lost if not for the passer-by.
Still, since it's an inexpensive watch, it's a good value for the price.
(Had a similar watch that I loved but it quit working in less than a year.)
