Seiko, a brand synonymous with reliability, accuracy, and affordability, has been a cornerstone of the watch industry for decades. The Japanese watchmaker is renowned for producing a wide range of models that cater to various tastes and budgets. One of the many reasons watch enthusiasts are drawn to Seiko is the brand’s modding potential. With a vast array of components available and an active modding community, there’s no limit to the creative possibilities when customizing a Seiko watch.

Today, we’ll look at the top 5 most accessible Seiko watches to mod. These models are popular choices for modding due to their affordability, ease of customization, and the availability of compatible components:

1. Seiko SKX007/009

The Seiko SKX007 and SKX009 are arguably the most popular models for modding. These iconic dive watches are known for their robust build, 200m water resistance, and classic design. The difference between the two models lies in the colour of the bezel insert, with the SKX007 featuring a black bezel, while the SKX009 sports a red and blue “Pepsi” bezel.

The popularity of these models means that there is a vast range of aftermarket parts available. Modders can easily find bezel inserts, dials, hands, chapter rings, and even replacement cases to suit their personal tastes. Additionally, the 7S26 automatic movement used in these models is well-known for its reliability and ease of maintenance.

2. Seiko SNK800 series

The Seiko SNK800 series, also known as the Seiko 5, is another popular choice for modding. This entry-level automatic watch is affordable and available in various colours, making it an ideal base for customization. With a 37mm case, 30m water resistance, and 7S26 movement, it’s a great option for those new to modding.

The SNK800 series offers a wide range of dial and hand options, allowing modders to create a unique look without breaking the bank. Additionally, the smaller case size makes it a suitable option for those with smaller wrists or those seeking a more vintage-inspired appearance.

3. Seiko SRP Turtle

The Seiko SRP Turtle is a modern reinterpretation of the classic 6309-7040 dive watch from the 1970s. The updated model features a larger 45mm cushion case, 200m water resistance, and the 4R36 automatic movement with hacking and hand-winding capabilities.

The SRP Turtle is an excellent choice for modding due to its distinctive design and compatibility with a wide range of aftermarket parts. Modders can easily source bezel inserts, dials, and hands to create a one-of-a-kind timepiece. On top of that, the SRP Turtle’s 4R36 movement can be replaced with the higher-end 6R15 movement for improved accuracy and a longer power reserve.

4. Seiko SNZH series

The Seiko SNZH series is a popular choice for those looking to create a “Fifty Fathoms” inspired mod. These 41mm dive watches feature a sleek design, 100m water resistance, and 7S36 automatic movement. The SNZH’s case design lends itself well to various bezel insert options, allowing modders to achieve a vintage look with modern reliability.

With a vast selection of dials, hands, and bezel inserts available, the SNZH series is an excellent option for those seeking a unique and affordable modding base.

5. Seiko SSC Solar Chronograph

Lastly, for those interested in modding a quartz watch, the Seiko SSC Solar Chronograph series is an excellent option. These solar-powered chronographs feature a 42mm case, 100m water resistance, and a reliable Seiko V175 movement.

While quartz watches may not be as popular for modding as their mechanical counterparts, the SSC series offers a range of customization options. Modders can change the dial, bezel insert, and hands to create a personalized timepiece. Additionally, the solar-powered movement ensures the watch remains accurate and low-maintenance.


Whether you’re a seasoned modder or just starting, Seiko offers a diverse range of watches that cater to various tastes and budgets.
