Best Gift

Feels cheap, but so far it's held up
Color: 2926 Silver Green
Looks as advertised, works well, and pretty water resistant thus far. Surprisingly water resistant. Unfortunately the band the watch comes with immediately felt a little cheap and flimsy to me. About a week after my purchase the band did inevitably break. The watch itself is still fantastic and everything works proper, like it should. Funny thing, I had left a review shortly after my purchase, talking about my dissatisfaction with how cheap the band felt. I have purchased many Olevs watches in the past and have had zero issues with any of them. I guess the company that makes or sells these watches read my review and asked about my dissatisfaction. I informed them of what happened, and they offered me a full refund. Originally I posted my review at three stars, just for that watch. All the other Olevs watches I have purchased are great. The customer service is so fantastic, this has never happened to me before so I am elated. They earned the five-star rating, and I would highly recommend checking out their collection of watches if you are a collector like me. I am overly confident if you do purchase one of these watches, and have any issue whatsoever with it, if you contact the customer service department they will be incredibly helpful as they have with me, and based off of my recent experience, I am sure they will do whatever it takes to make things right with you. Well done, very surprising customer service department. Very refreshing these days. Based on customer satisfaction alone they get five stars from me!
