Description
Silver-tone stainless steel case with a black rubber strap. Uni-directional rotating black PVD stainless steel bezel. Black dial with luminous hands and index hour markers. Minute markers around the outer rim.
Dial Type: Analog. Luminescent hands and markers. Day of the week and date display at the 3 o'clock position. Automatic movement. Scratch resistant hardlex crystal. Skeleton case back. Round case shape, case size: 40 mm, case thickness: 12.5 mm. Band width: 22 mm.
Tang clasp. Water resistant at 100 meters / 330 feet. Functions: date, day, hour, minute, second. Sport watch style. Watch label: Japan Movt.
It is Seiko proprietary and used on most of their watches. It's way better than average mineral crystal. Plenty of scratch tests etc out there to show it is quite good. Better than just about anything except for sapphire ofc.

I own this watch. Purchased it around 5 years ago. Looks great! I wore it for about two weeks and put it in a drawer because it couldn't keep time worth a darn. It would be off 5 or 10 minutes every 24 hours. Mine could have been a one off. I hope your experience is better.
All quartz watches depend on a vibrating quartz crystal to count time. The quartz vibrates slower and faster depending on the temperature.
Most watches should not vary more than 5 seconds per day, otherwise, you got a lemon and need to exchange it or have it repaired.
It might be possible to adjust it if you can get a service manual and the module allows for this without a ton of extras.
That's kinda the sieko thing. You get a 30 second a day variance commonly. But with some regulation time, you get it better. But every now and then, you just get one that is a mess and never really regulates well, magnetized or not. I'm wearing a nh35 now and it's about 2 seconds fast a day (after lots of regulation). But every so often I can get a weird 5 or 10 second off day. They just aren't rock solid steady like some other moments.
Let's say the watch is calibrated and adjusted at 25C, but then you're using it in a 30C environment all the time. Crystal will run at a different speed, affecting accuracy.
If the movement allows for fine tuning, you can adjust based on the typical temperature (the wrist temp) for better accuracy.

Thank you for this data, but the product being discussed is not a quartz watch.
"Automatic" movements are mechanical movements which depend upon properly regulated balance springs, and these are also affected by temperature variations (like almost everything else). However, many other factors will influence the accuracy of mechanical watches, like gravity, friction and dial position (all inter-related).

No offense, but I'm a watch nut/collector. I have tons of mechanical movement watches (and a couple quartz and radio citizens). as others have said, we are discussing a mechanical watch, not quartz. 5 seconds per day would be among the BEST mechanical movements.
Mechanical movements come in grades. The higher the grade, the more STEADY they seem to be. Meaning, the same error over and over reguardless of temperature, position, etc. that's what a cosc or meta certification is telling you. In reality, for example, my planet ocean omega is +2 seconds a day almost always, no matter what happens to it. Same thing with Rolex, the same rough difference every day.
Seiko regular movements are no where near that same category. They claim about +/- 30 seconds a day, and that's probably fair. You can manually regulate them in multiple positions, and expect to maybe average +/-10. But you'll get some inconsistent days, where they are just bouncing all over. you also get some duds out of the box. That's why they are cheap.

Between this and the hardlex instead of sapphire, I'm staying away from this one.

Pop a new NH movement in there off AliX for $30. Usually that workhorse movement is great.
Is it only me a $134 watch that doesn't show the correct time? I mean I understand that mechanical watches are more like a novelty than necessity but I thought quartz watches were accurate enough to not have to adjust them that frequently where you would actually remember when you did so. I liked how the watch looks and I do have some nostalgia about a Seiko 5 but I am going to pass because I am wearing watches that do a lot more than just telling time.

It's cheap enough, not a terrible deal....but I don't like the lack of hacking. But that's just me.
