The watch has a problem with the alarm.
Color: Black/Black/Digital, Color: Black/Black/Digital
This is perhaps the nicest digital watch I’ve ever had, the watch is new, but it came broken, the alarm does not sound or better to say sounds so low, it is inaudible, is practically useless, do not know if it can be fixed, I’ll have to take you to a technician, the problem is that I am in Ecuador, I do not know if the guarantee will serve or can be returned.
-------------------------
Este es quizás el reloj digital más bonito que he tenido, el reloj es nuevo, pero me vino averiado, la alarma no suena o mejor dicho suena tan bajo, es inaudible, es prácticamente inservible, no sé si se pueda arreglar, voy a tener que llevarle a un técnico, el problema es que estoy en Ecuador, no sé si sirva la garantía o se pueda devolver.

Beautiful watch! Great color. Waterproof. Looks pretty with bracelets. I purchased another in a different color… but It wasn’t as good of a price as this Seller! Recommend!

Love it!
Color: Light Blue
Great summertime watch. Wore it all the time. I resized it much smaller, but easy enough to do. Completely waterproof. Would buy again...and did in grey for the winter. Highly recommend.

Such a cutie, but my wrist was too tiny
Color: Light Blue
as most reviews stated, you need to go to a place to remove some of the pieces and make it adjustable to your wrist
