Great watch, would recommend
Color: blue watches 58, Color: blue watches 58
I really like this watch because it looks amazing. It’s much lighter than I expected, so it’s comfortable to wear all day at school without feeling heavy. When I first got it, the metal band was a little bit squeaky, but after wearing it for a while, the noise completely
stopped. I had to remove a few links to make it fit my wrist, but the adjustment was actually really easy to do yourself. The clasp is great too it stays closed and it doesn’t pinch my skin at all. The blue and gold colors look awesome together, and it’s definitely a great watch for the price

My new favorite watch. Simple home improvement needed
Color: all black watch mens, Color: all black watch mens
Despite having many reknown brand watches in my collection, these inexpensive Olevs watches are now my favorite.
They look nice, cost practically nothing and so far are very accurate (10 day review). Little to worry about if lost or damaged.
PROS:
1. Inexpensive $40/each.
2. As stylish as other fashion watches 5x-10x more expensive.
3. Watch Crystal (i.e., glass) has a unique, faceted shape, which reflects light, feels "Manly" and matches faceted bezel.
4. Light weight and slim case; fits small wrists nicely (I have 6.4" wrists).
5. Accurate - two watches tracked over 10 days. Watch one: -7 seconds/10 days. Watch two: +2 seconds/10 days.
6. Illuminescent (i.e., glow-in-the-dark) hands and watch face look decent in dark.
CONS:
7. Lightweight and cheap material - durability is questionable, especially coatings.
8. Bracelet/band links have excessive gaps to each other and rattle badly, making watch noisy and embarrassing. *Home fix*
9. Faceted Crystal can make it difficult to see exact time, because of light reflection.
10. Single clasp on bracelet could easily open inadvertently, vs double clasp.
11. Crown is not threaded and spins freely, even when closed (doesn't change time); likely poor water proofing and crown can easily open.
12. Difficult to set time accurately; crown movement is figity and closing crown can cause hands to easily move.
13. Second hand doesn't exactly line up with tick marks making it difficult to know if actual time is before, or after tick mark.
*AT HOME FIX*:
To fix the noisy bracelet, simply cut to length a piece of waterproof medical tape 15-16mm (5/8") wide, then attach to inside of clean bracelet, while spreading the links apart with your finger (i.e., stretch band). Do this on each bracelet, but don't cover clasp. Tape will need to be replaced, as it gets dirty, but it makes watch quiet.

It's a watch
Color: blue watch for men
Not a bad watch. Cheap, looks good and works.
Take it to your local jeweler and they can pop the links out in no time.

Nice But Overpaid
Color: Black Embossed
Very happy about the purchase. The style is great, size is perfect, and the leather is really nice. When I unpacked it, the MSRP ticket was inside showing the cost of $125, but I paid $150. Not so happy about that part.
