This watch stopped working the day after Amazon accepts returns. I had only worn it twice. I had another similar watch which worked fine. I don't see any warranties from the manufacturer for this item. So a waste of money. Also for the 30 day return - I received this on January 11, it is February 11 - I should be able to return for refund.

Must wind the time adjustment knob in for it to work!

Its a gorgeous watch and I love the clasp design and band material. It works if you: 1. wind the time adjustment knob with the knob IN/towards the watch 2. pull out the time adjustment knob and wind the side button to change the time or 3. shake it hard- it starts and stays moving easily after that if you are walking/swinging your hand around. I dont know how long each wind/twist lasts but winding it (knob in) will keep it moving even if its just sitting. Options 2 or 3 only keep it moving temporarily. The band and clasp are really smooth and comfortable. The watch itself isnt too thick and the band is extremely easy to adjust to a custom fit (screwdriver and instructions included for adjusting the clasp location). Its really comfortable for an all day wear, is subtle for everyday wear but classy when looked at up close. For under $35 this is a gorgeous, simple watch and significantly cheaper than most of the others I've looked at. Havent tested under water yet though
