All functions work, it syncs to your phone with an app, I've used it on both an iPhone and Android. The lugs show some wear from changing straps, it's a plastic case. I have several spare batteries I will include as well, while the battery is supposed to last up to 2 years that's a bit of an optimistic goal. I never wear it, originally it retailed for something crazy like $1000. I feel like a trade for a Moon Swatch is pretty fair and even given this can act like a 'smart' watch with step/sleep tracking, ABC functions, etc. Review here: [https://www.ablogtowatch.com/alpina-alpinerx-smartwatch-review/](https://www.ablogtowatch.com/alpina-alpinerx-smartwatch-review/) I would not get it wet as I have changed the battery myself and can't be sure to it's water resistance. If I need a kicker to make the trade I also have a Sunnto Core I'd throw in. Yes this trade is very much in your favor.
