Review: Very nice for a $30 automatic - My son was looking for an automatic mechanical watch after getting frustrated with his quartz watches having dead batteries, so I got him this as a starter mechanical watch. We knew going into the purchase that for $30 we shouldn't expect to much. To our surprise the watch exceeds our expectations. Overall, the look and feel seems to be solid, better than I expected. Even the rotating bezel has a nice feel to it and decent sounding clicks. Once it's running it keeps decent time, and he says it is comfortable to wear and he likes the looks, so it's being used regularly. My son's one complaint is that the power reserve seems a bit limited. The watch has a hand winding feature, so it is possible that the auto-wind feature just doesn't supply enough over the day. I think it might be best to hand-wind before wearing, but it's not my watch and the fact that he has to set it in the morning isn't an issue. All that being said, we like the watch and would recommend it for someone who wants to dip their toe into the world of mechanical watches and stop dealing with batteries. The watch we purchased has the stainless steel bracelet and it arrives at full size, which was too big. Fortunately they included a device to drive the pins out to resize the bracelet. This device is probably good for three of four re-sizing's, it's just very cheap, but it got the job done. If you are considering trying an auto-winding mechanical watch feel free to give this one a try. It's actually very impressive considering the low cost.
Review: Worst watch ever!!! Don't buy! - Purchased last month, watch don't keep time,date is not aligned with the magnifying window. Ordered a replacement and it was even worst. When setting the time on the replacement the whole watch movement pull to the right witch means that something was missing inside the watch or not properly sit. To make it short, seller is not aware of quality issues. It is sad because the watch is very nice looking. Definitely will not buy from Mastop seller anymore.

### ⭐⭐⭐⭐⭐ Way better than expected-The timekeeping is outstanding.
*by C***N on March 22, 2019*

For the record I tinker on watches as a hobby. Why am I buying this then?. I wanted a beater automatic with a date-and waterproof. Waterproof on older watches is very hit-miss and they are intrinsically more valuable than I care to wear on a casual basis. I have a timing machine so I checked. This watch as delivered was very close to perfect in poise & beat error. Over the 1st 3 days I gained / lost 3 seconds and now it has settled down to a -1 sec a day. That's way better than most expensive watches. The cons: The band is ok-especially for the price. But the link pins are solid not split-making sizing a royal pain-hard to drift out properly. And the fake Pepsi bezel rotates one way & clicks well-but is not secure and loose on one side. That's it so far. The amazing: The poise-or positional error-is near zero. This makes the watch keep good time in any position. In general the Asian movements have good timekeeping . This one however is near perfect and that is so very hard to do. I can only assume they have a clever machine that does the balance error adjustments on the balance wheel. ------------ No problems of note but just a week in. If it blows up or has a odd failure I'll report back. By any measure this is a tremendous value for a mechanical automatic watch.
