Key Features – Benefits of Seiko SNK805

Automatic Operation

What does this mean? The big plus of automatic watches is you never need to add a battery. That’s because these wristwatches get their juice from arm movement. So all you have to do is follow your daily routine 8+ hours/day to keep the watch’s glow-in-the-dark hands turning.

Day/Date Display

This Seiko watch includes a display that tells you the current day and date. What’s the big deal? We’ve all lost track of the date and even the day for various reasons.

Couldn’t you use your smartphone or tablet to get this info? You could, but it’s less convenient than a wristwatch that’s always within arm’s reach. Just glance down at the SNK805, and you’ll know the day of the month and day of the week.

Mineral Crystal Glass

This watch includes a window made of mineral crystal. It’s scratch/impact-resistant and is used most off in the watchmaking industry.

Mineral Crystal class provides several features. They include high strength, clarity, and reflection.  It’s also more cost-effective than other options, so it helps to reduce the watch’s overall costs.

Auto Watch Winder

You have a few options for “charging” this automatic watch. One is to wear it 8+ hours a day, and another is to turn the crown to wind the unit’s main spring.

Another option is the automatic watch winder that’s sold separately. This is a storage unit that keeps the watch wound up when it’s not in use.

For example, let’s say you don’t need to wear your watch one day for whatever reason. You can keep it wound up by storing it on the auto watch winder. The timepiece can then be used whenever you’re ready.

Analog Display

Fun Fact: Hamilton released the world’s first Commercial electronic digital wristwatch 40+ years ago in 1972. Analog displays are old-school, and that’s a good thing for many consumers.

Many shoppers for wristwatches are looking for units with the traditional look and feel of analog displays. What’s old is new again. Another plus is reading such displays can give your mind some exercise. You tell time instead of the watch telling you the time.

Nylon Strap

The SNK805 features a green nylon strap that includes a buckle closure. It’s fair to say this isn’t the world’s top watch band. That said, nylon provides some benefits like absorbing perspiration better than rubber.

What if you’re still not happy with the strap? It could be argued the strap is this Seiko watch’s weakest link so if you wanted to swap out the green nylon strap you’d still get a high-value watch for the price point.

Military-Inspired Design

If you want a wristwatch that looks like it’s military-issued, then the Seiko SNK805 is a great option. That includes the luminous accents, green dial,  and green strap. It offers a traditional yet classy look that never goes out of style.

Steel Case

This Seiko watch isn’t the most durable one, but it’s sturdy enough. That’s due to factors like the steel case that helps protect the interior components of the watch. This adds value to the SNk805.

Price Range

Do you have $55 million for a watch? If not then you should consider the Seiko SNK805. This wristwatch is in the under-$100 price range so a good option if you’re on a shoestring budget.

While this watch offers a rock-bottom price, it includes high-value in terms of aesthetics, functionality, and so on. So in some ways, you get more than you pay for.

Versatile Watch

Another plus of the SNK805 is it offers lots of versatility. You can wear it as a casual watch to work or on the town. It’s also a practical option for outdoor use like hiking and camping.

Water Resistance

The SNK805 is water resistant for a maximum 30 meters (99 feet). That doesn’t mean you should consider scuba diving with the unit.

How water resistant is the watch? The unit can basically withstand some splashes or being immersed briefly in H2O. That said, you should consider not swimming or showering while wearing the SNK805.

Once again, this model offers tons of value/features for the price. If you want a basic everyday watch that will still work in light rain or splashes from sinks or sprinklers, then the SNK805 is a wise choice.

Why doesn’t the watch need batteries?

This automatic watch gets is power from your arm movements rather than batteries. All you have to do to keep the watch running is to wear it 8+ hours/day. This can save you a ton of money you’d normally spend on watch batteries, which usually end up in landfills.

What is the water-resistant depth?

It’s technically 99 feet. However, it’s not recommended that you swim (let alone dive) with the SNK805.

What is the watch winder?

The automatic watch winder is a “charging station” of sorts. In between times, you wear the watch you can store the timepiece in the storage unit. This keeps the watch ready to wear since it stays fully wound.

It’s an alternative to manually winding the watch. Which option is better? If you wear the watch regularly then winding is practical.

However, when you won’t be wearing the watch for 1-2 days, for example, the auto watch winder is a plus. It prevents the rigmarole of winding up the watch constantly.

How precise is this watch?

The SNK805 is a mechanical watch that generally keeps good time. Its precision is based on a wide variety of factors. So if you want pinpoint accuracy, then this isn’t a good watch for you.

Even if you wear the watch 8+ hours a day, you should still expect to lose several seconds. This isn’t to say you should automatically shop around because of the watch’s accuracy. It’s simply not built for accuracy to the second.


We’ve just taken a close look at the product featured in seiko snk805 Automatic reviews. We’re ready to share our final verdict. Like other watches on the market, this Seiko watch has its plusses and minuses. The main benefit is the under-$100 price range that offers big vale.

Is SNK805 perfect? It’s not, and you should expect it to be for the price point. It doesn’t keep perfect time and easily loses about 10 seconds/day when worn for 8+ hours. Another drawback is the non-hacking movement that doesn’t let you stop/set the second hand.  The biggest “issue” with this Seiko watch is easily the green nylon band.

All of that said the SNK809 is still an automatic watch worth considering. Besides being an affordable entry-level automatic watch, it has some big plusses. They include the steel case,  water-resistance, and battery-free operation.

The biggest plus of this timepiece is arguably the aesthetics. They include a military-inspired look with green dial, day/date display, and glow-in-the-dark hands.

In fact, online reviews of this watch typically give this watch the highest marks for its appearance.  The SNK805’s aesthetics make it look a lot pricier than it actually is, which isn’t really a bad thing for a cheap watch.

So what’s the bottom line? This Seiko Automatic watch is an outstanding choice for an entry-level unit. It has its downsides including the durability, precision, and most notoriously—that green strap. However, we think it’s worth swapping in a new band so you can keep all the watch’s perks.

The watch in this Seiko snk805 review also includes some key plusses including automatic functionality, water resistance. The biggest plus is the aesthetics including the army watch-like look,  Arabic markers, and green dial. Your future with this automatic watch can be as bright as the illuminated accents.
