Question 1

How do you set the second hand? I can't seem to find a way to do that.

Accepted Answer

The movement this watch is equipped with is called the 7S26. It is the least expensive version of the 4R family of movements. As such it lacks the ability to hack or handwind. Hacking is the ability for a movement to stop its second hand. With a quartz watch this is easy, but a mechanical watch needs a spring or a clutch to stop the second wheel. Seiko watches with the 4R35 and 6R series of movements have hacking and hand winding along with other upgrades and accuracy improvements.

Question 2

Got this a week ago, and I've been wearing it everyday, but it stops every couple of days. Does it have to left faced up, flat when not being worn?

Accepted Answer

I know the original question is from 3.5 years ago; but, for the benefit of new people researching this watch:  This movement has a maximum of about 36 to 40 hours of reserve when fully wound (advertised ~41 hours).  To expect an automatic watch at this price point to go longer than that is just ludicrous.  If you have worn it all day, that should get you through at least overnight.  Give it the "Seiko shake" (hold face up and shake it back and forth) for about a minute to ensure it lasts through the night...I don't think you need to, but it adds a bit of tension to your mainspring and can't hurt.  If you take it off Friday and not move it until Monday morning, it would be an unrealistic expectation that it will still be running.

Question 3

Are hands visible in the dark?

Accepted Answer

There are two common way to make 'glow-in-the-dark' things: radioluminescence and phosphorescence.

Radioluminescence is when a material lets off light on its own because it's slightly radioactive. High-end watches use radioluminescence for their features.

Phosphorescence is the much cheaper alternative that's commonly used in glow-in-the-dark plastic, toys, and paint. The key difference is that it doesn't generate its own light--it's charged by sunlight like a battery and releases at night.

This watch uses phosphorescence for its features. If you wear it outside, uncovered, and in the bright sunlight all day, it should stay glowing all night long. If you work indoors or cover your watch with your sleeve during use, it may not make it all the way through the night. This effect will also weaken over time--but rest assured it should still glow for a few years at the very least.

Question 4

Are the canvas bands that come with the watch replaceable? If so, where can I find them?

Accepted Answer

Hello John, you can certainly replace the band and there are many beautiful bands on amazon. I am not sure about the specific canvas band but you should be able to find a nice one for your watch. Just look at the technical details for the band size and happy hunting. PS: You might not want to spend too much time and money buying a new band as the watch is prone to failure after a couple of months. Mine is caputt and in the trash already and even with the warranty, you will spend more time and money sending it back and forth than the $60 you paid for it.
