The box comes with 2 watches and a tool that is supposed to help you take out the links to correctly size. The watch bands are huge, several links will need to come off to make this wearable. The tool they sent immediately broke and once you get the link out its nearly impossible to put the pin back correctly. Additionally I set both of the watches to the correct date/time and within 24 hours they were both incorrect. One was 5 minutes slow and the other was 2 minutes slow. The loose band makes it uncomfortable to wear given how heavy the watch is, not worth even the currently low price

Overall Bad

Color: Rose Gold

Impossible to adjust length. Comes with instructions and a tool that do not work out. Watch is way too big and not usable. Time is very hard to set and doesn't sense touch as well as it should considering that's it's purpose.

Total piece of Junk

Color: Gold

Great looking watch, but unfortunately it is a total piece of junk. Almost impossible to set, changes time while sitting and battery dies within a week. Don’t waste your money.
