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.

Looks Like a Watch
Even for a $23 watch, there are a few things that pretty much have to be included. First, one should be able to set the time on the watch, which this watch was initially not capable of doing. It still takes fingernail damaging force to get the winding stem into the time setting position. Next, the winding weight, which is visible through the glass back, initially didn't rotate, so the watch did not wind while wearing, pretty much what an automatic watch is supposed to do. It seems to be breaking in, but if something else screws up, back it goes. And it did. The automatic wind function does not work so the watch is a paper weight. It is going back.

Way better than expected-The timekeeping is outstanding.
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.

Not terrible for first automatic watch
For the price you can't have high expectations. It doesn't look to bad and it's hard to find an automatic watch for such a low price . For the price it's nice and at distance looks nice.The bezel feels like if you push it hard it will pop off . The bracket feels cheap and tin like and the date window on the glass sticks out. With that being said if you are expecting a very cheap beater automatic watch this will do well it wears on the wrist okay . Looks half decent on nato or leather straps if you're planning on a daily wear option be aware it doesn't seem like it can take to much damage

MASTOP - Reloj mecánico automático para
This automatic watch is absolutely amazing! The quality is much better than I expected. It looks very elegant and stylish, and it feels solid and well made on the wrist. You can really tell it was designed with attention to detail. One of the best things about this watch is that it runs automatically without needing a battery. As long as you wear it, it keeps working perfectly. The movement is smooth and the timekeeping is very accurate.

Fun Toy
First of all, you have to have realistic expectations. This is a $20 mechanical watch, which is insane. I'm told you can buy the bare Chinese movements for about $4; presumably it's even cheaper when buying in bulk. How they are making something so complicated so cheaply is a mystery. But, the band is soft and cheap, the movement feels delicate when winding, and there is no -- zero -- waterproofing. If you get it wet, you can count on the parts inside rusting and the watch stopping in a couple of weeks. Anyway, as you can see from the picture of my timegrapher, in dial up position it gains 5 seconds a day, has a 0.1 millisecond beat error (which is excellent), and a robust amplitude of 261 degrees, which means there is a good amount of force in the hairspring. These results are better than some much more expensive watches I own, like my Hamiton Khaki King. Things change for the worse when I move the watch into different positions on the timegrapher; of course, when you wear a watch, it doesn't sit dial up very much... it runs in a variety of positions as you move your arm about as you wear it. But on average, the watch keeps pretty good time for a mechanical watch at any price point. More expensive watches fare better at different positions (crown down, dial down, etc.) than this one does, likely because the movement here has never been calibrated. I also notice that the timegrapher shows some noise on the second beat. Not sure what that is, but it lends to the impression that the movement is a little iffy. As I mentioned, winding the watch feels delicate, and I’m not sure the clutch is engaging properly, so it may be possible to over wind, and thus damage it. Similarly, the autowind rotor seems reluctant to turn (possibly related to the clutch), so I expect it won’t be long until the watch no longer winds itself and must be hand wound every day. But, that has not happened yet. Another issue with almost any watch that has a date complication: make sure, when setting the date, that the hour hand is not between around 9:00 and 3:00 (p.m., but you can’t tell which a.m and which is p.m. until the date changes). That is around when the date change mechanism is engaged in the watch, and if you try to change the date during that time, you will break the watch. That is particularly true with an iffy movement like this one. On my copy, the date begins to change at around 10:00 p.m. and doesn’t really finish until around 3:00 a.m. That’s not great, but not unexpected in a $20 watch. Once the date has completely changed, it’s a bit off center in the date window. The watch itself feels feather light, like cheap costume jewelry, but it looks nice from a small distance. It rattles and generally feels like a toy and I don’t expect it’ll be running this time next year. But you never know. The thing is though, to me this is worth $20. I have enjoyed the experience of checking out what a $20 watch is like, and since it keeps good time, I think I’m going to add it to my collection and give it some wrist time. It’s the only electric green watch I have; I think it will look shocking on a bright orange silicone band. Used as an every day watch, I don’t think it would make it very long. But added to a collection and worn occasionally, it should make it for a long enough time that $20 becomes a crazy value. So I would say this: if you’re ok with parting with $20 for a working mechanical watch, and understand that it is not built to last, this is a fun thing to play with.

A good watch for those who want to buy their first automatic watch
I bought this watch out of curiosity to own an automatic watch at an affordable price, and I was pleasantly surprised. I've had the watch for over a month now, and it's working perfectly. A good purchase for those who want their first automatic watch at a reasonable price.

Don’t, Just Don’t. Look Elsewhere.
Don’t purchase this watch. I didn’t expect a lot from a watch that’s this inexpensive. I got even less than expected. The watch randomly stops and starts. It will keep time for a few hours then just stops in the 1:00 position. Then if you shake the watch it starts back up. It’s almost impossible to set the date without moving the hands through full rotations because pulling the crown into the proper position is non existent. Lastly the movement is loud.

SO FAR SO GOOD / no good at all
IT IS TOO SOON TO TELL. ONE THING IT IS UP TO CRAP FOR IS HOW TO CHANG THE DATE YOU HAVE TO DO A 24HR WIND FOR EACH DAY. WHY NOT JUST PULL THE WINDER OUT SO FAR TO SET THE DATE I STILL HAVE NOT SET MINE YET TOO SORE ON THE FINGERS. IT STOPS SO OFTEN ( JUNK )
