The Best Seiko Watches for Modding: Part 2

In the previous article, we listed down the best Seiko watches that can be modded. If you were left hanging, don’t worry because this article will continue the list. The watches listed in this article are also part of the same product line, and all of them are also based on the Seiko 5.

Let’s get right to it, so that you can immediately begin your Seiko modding journey—read on below to learn more.

#3 – Seiko SKX011

The SKX011 was also launched in 1996, alongside the SKX007 and SKX009. Unlike the other SKX watches, the SKX011 was released with two variants. The first was the SKX011J, which was manufactured in Japan. The other one was the SKX011K, which was manufactured in Korea. Unfortunately, the SKX011K has not been around for quite some time already, so we can only focus on the SKX011J.

Like the SKX007 and the SKX009, the SKX011J also uses the 7S26 movement. The movement is that of a workhorse, which offers an accuracy of +20 and -40 seconds a day. Additionally, the movement is also non-hacking and non-winding. The thing about this watch movement is that it can be replaced easily, and the accuracy is more than enough for some people. Its power reserve boasts 42 hours as well, which can be pretty handy.

For its physical features, the SKX011’s case is measured 42mm in diameter, and its lug-to-lug length is estimated at 45.5mm. With these physical features, it’s slimmer than that of the SKX007 and SKX009. It’s also lighter because it weighs a mere 3.68 ounces. It’s also a perfect watch to use while diving.

#4 – Seiko 5 SNK809

What many people don’t know about this watch is that it’s not just an homage to the original Seiko 5, but it’s also the latest version. The Seiko 5 has been in production since the ’60s, with minor variations. Its design was specifically created to meet specific requirements, which are:

  • Automatic movement
  • Impressive water resistance
  • A day and date window
  • A 4 o’clock crown
  • A robust design

These standards can still be found in the Seiko 5 watches that are manufactured today. The difference between the SNK809 and the SKX series is the face. The SKX series has a bolder scale, while the SNK809 has a more sophisticated look. 

There’s also an inner ring with Arabic numerals placed at the hour positions and an outer ring with a 60-minute scala and 5-minute readout. The hands are shaped like long diamonds, with a finish that can be read in the dark. The scale and numerals are also illuminated and can still be seen in the night despite their size.

#5 – Seiko 5 SNZF15

This watch is another variant of the traditional Seiko 5, but with one significant difference. It uses a 7S36 movement instead of the original 7S26, which is an upgrade in itself. However, this watch is a more traditional one, which uses a 3 o’clock crown. It’s also rated for a +40/-20 seconds per day. 

The watch is also prone to errors because its outset can be off by more than a minute per day. For this reason, Seiko recommends wearing it for a few days, then leave it be until the 40-hour battery life is no more. Once it’s wound up, it should usually work again.

The watch’s face is similar to the SKX009 because it also uses the “Pepsi-style” bevel. Additionally, this watch can also be used for diving but only use it at your own risk because the SNZF15 is not certified for diving use. While it’s visible underwater, it’s inferior to other watches on the list.

As for other physical features, the SNZF15’s case is measured at 42mm in diameter and 13mm thick. Additionally, it also has a Hardlex mineral crystal that’s resistant to scratches and shatters.


That completes our list of the Best Seiko watches for modding, but the choice of which watch to mod is entirely up to you now. All of these watches are reasonably priced, especially for a luxury watch brand like Seiko. These watches are optimized for diving use, so make sure to mod them accordingly.

Often, it’s hard to get mod parts, especially if you don’t know where to start. Luckily, many shops offer a wide range of selections when it comes to mods.
