Seiko SKX009 vs Citizen NY0040 – Affordable Diver’s Watches

Seiko SKX009 vs Citizen NY0040

Today, we will be comparing two amazing yet affordable automatic Japanese diver’s watches.

The first watch is the Seiko SKX009, the blue and red counterpart of the famous Seiko SKX007 which is the all black model.

On the right side, we have the Citizen NY0040 which is one of Citizen’s last automatic watches that is still in production today.


The Watches will scored between 1-5 for the following:

  • Value
  • Design
  • Movement
  • Brand Prestige

They will then be given a total score out of 30, which will be calculated into a percentage for each of the two watches.

We hope you enjoy this VS battle of these two Japanese automatic diving watches, and without further ado, let’s get started!

Please note that this is a comparison and not a review. Even though you probably will learn some new things about these two timepieces, this is simply a comparison and doesn’t list all the specifications of the watches.

Also you may disagree with the opinions and conclusions reached in this comparison, and that’s totally ok! Everyone is entitled to their own opinion. Please let us know in the comments below if you have anything to say or add.


Seiko SKX009 – 4/5

Depending on where you’re at, the Seiko SKX009 can have a slight difference in pricing, but when bought with the metal jubilee style bracelet, it is usually around the £150 mark for the UK, and just under $200 in the US.


For the money, you get a robust, ISO certified scuba diver’s watch with a depth rating of 200m. It also features a very robust and solid feeling stainless steel case, uni-directional 120 click diving bezel and very bright luminous markers on the hands and the dial.

Powering this watch, is Seiko’s famous 7s26 movement, which is famous for being extremely tough, as well as very easy and cheap to service or replace.

However, the issues include the fact that it cannot be hand wound and it is non hacking. But, as a Seiko made automatic it utilises Seiko’s magic lever winding system which allows the watch to wind while the rotor is swinging clockwise as well as anti-clockwise.

This watch deserves a 4/5 because on the whole it is amazing in quality, the only downfall really is that the movement doesn’t hand wind which can be a deal breaker to some people.

Citizen NY0040 – 5/5

The Citizen NY0040 is definitely in the same price bracket as the Seiko SKX009, coming in at around £150 in the UK, and roughly just under $200 in the US.


Just like the Seiko SKX009, it is an ISO certified scuba diver’s watch. Unlike the Seiko however, it does not have a magic lever, but still features a very robust automatic Miyota movement, which is significantly more accurate than Seiko’s 7s26, gaining under 5 seconds a day, whereas the 7s26 is usually closer to the range of +-10-15 seconds a day. It also offers a hand winding feature, which makes it stand out significantly from the SKX009.

What really stands out most about the Citizen is the fact that it looks like a much more expensive piece, sporting beautiful silver trimmed markers on the dial, with much more attention to detail than what the Seiko has.

The bezel is uni-directional with 60 clicks, however is much more difficult to turn giving it a more rugged and robust feeling.

The Citizen gets a well deserved 5/5 for value, as it sports a much more detailed finish, a hand winding movement and a rugged dive bezel.


Seiko SKX009 – 4/5

The Seiko SKX009 features a very plain and simple design throughout, made like a true tool watch which it is.

It features a red and blue ‘pepsi’ style bezel, which makes it stand out on the wrist achieving looks through function.

The Seiko’s Crown is at the 4 o’clock position, putting it out of the way so it doesn’t dig into your hand as much when you move your wrist.


It offers a day-date display which has a white background, making it stand out from the rest of the dark blue dial.

The case is nicely rounded, with a matt finish on the top and shiny sides.

The case back shows Seiko’s Tsunami Medallion, which is a classic mark on all of their diver’s watches.

Overall, the Seiko deserves a 4/5 for design, as it is very good looking and functional. The downside is though that it is a little too simple in design with little detail, however as a diver’s watch there is of course a reason for it.

Citizen NY0040 – 5/5

The design of the Citizen is immaculate, featuring an absolutely beautiful, detailed dial with plenty of personality in the way that the hands and markers are designed.

The black bezel and green dial with the slightly green lume marks give this watch a unique and mysterious feel.

The crown is at the 8 o’clock position, giving this watch a unique touch. This means that it will not dig into your wrist at all as many other watches do. It also means that the crown is less likely to get hit by something, thereby making it more protected.


It also offers a day-date display, however it has a black background, making the overall dial look better, but making it harder to read at a glance.

On the back of the case is Citizen’s Promaster famous arrow logo, which is also on the dial in red under where it says ‘Citizen Automatic’.

The Citizen get’s a well deserved 5/5 here as it has many much more unique aesthetically features about it, striving with a more complicated and stunning design than the SKX009.


Seiko SKX009 – 4/5

As mentioned before, the Seiko SKX009 features a Seiko 7s26 movement known for it’s robustness and longevity above all.

Even though it is not the most accurate automatic of all time with an accuracy of around +-10-15 seconds a day, it makes up for it for being one of the most robust automatic movements of all time, especially at this price point.

I have read online that several people have stated that they have had Seikos with the 7s26 movement which lasted them over 15-20 years without a service! This is phenomenal for any automatic watch movement especially in this price bracket.

You should still get the watch serviced at regular intervals though if you want it to work at it’s best and last you for a very long time.

The downsides are that it is unfortunately not amazingly accurate but also doesn’t hand wind which is a deal breaker for some people, and certainly an annoyance if you don’t wear the watch every day.

Overall, the Seiko SKX009 gets a 4/5 for it’s movement.

Citizen NY0040 – 4/5

The Citizen NY0040 features a very tough Miyota movement which is very comparable to the Seiko 7s26 movement used in the SKX009 as it features a day date.

As mentioned before it is a much more accurate movement than the 7s26, with an accuracy of roughly +-5 seconds a day at most.

Unlike the 7s26, this movement has a hand winding feature, however it is not quite as robust as the legendary 7s26 movement by Seiko but still very tough.

On the whole, the Citizen get’s a 4/5 because even though it is more accurate than the 7s26, it isn’t as robust or as legendary and well regarded.

Brand Prestige

Seiko SKX009 – 5/5

Seiko has been making the SKX007 (the all black version of the SKX009) since 1996.

They are third most seen watch brand in movies, and are generally very highly regarded all around the world for their outstanding value and quality.

Seiko is also known for many technical achievements such as making the first commercially sold quartz watch back in 1967.

Many watch enthusiasts are of the opinion that Seiko is always the best pick for whatever price category it stands in with very few exceptions.

Even James Bond, 007, wore a Seiko in several James Bond films.

For being as outstanding as they are, Seiko get’s a very well deserved 5/5 for brand prestige.

Citizen NY0040 – 3/5

Citizen is still an amazing brand, however it is nowhere as widely known and admired as Seiko is.

They own other companies such as Bulova, which is known for it’s technical achievements more so than Citizen themselves.

Again, there is nothing wrong with Citizen, they are still an amazing brand with some great watches and innovative technology such as Eco-Drive, they just aren’t as well known and the brand perception and prestige isn’t comparable to the legendary Seiko.

Citizen get’s a respectable 3/5 for brand prestige, which as it is not amazing, they are still a decent watch brand.

It’s a Draw!

Through this comparison, it surprised me that the watches drew overall!

For me personally, on some days I prefer wearing the Seiko, and on others I prefer wearing the Citizen.

Overall, I personally find the Seiko just a tiny bit cooler because of it’s history, Seiko’s history and the iconic design with the Pepsi bezel.

If I could only have one though, I would probably pick the Citizen as it’s black aesthetic makes it just that tiny bit more versatile than the Seiko SKX009.

    Good overview, Karl. I have the 007 and just got my Citizen this past week. Both are nice watches for the money, and the only reasonable action is to buy both!

    Keep up the good work!

    Good comparison, both great watches. I to prefer the SKX, it just seems to be one of those occasions where everything comes together in one place and is pretty near perfect.
