A Guide to the Art of Creating Custom Seiko Watches

Seiko watches are renowned for their quality, affordability, and versatility. As such, they are often considered the perfect canvas for modifications, allowing watch enthusiasts to create unique timepieces that reflect their personal style and taste.

That said, modifying a Seiko watch can be an exciting and rewarding experience, but it requires patience, precision, and a good understanding of the process. This guide will walk you through the key aspects of mastering the art of modifying Seiko watches, from choosing the right model to the actual modification process:

Choosing the Right Seiko Model for Modification

Before diving into the world of Seiko modifications, it's crucial to choose the right base watch to suit your needs and preferences. Seiko offers a wide range of models, but some are more popular among modders due to their availability, affordability, and compatibility with aftermarket parts.

1. Seiko SKX007/009

One of the most popular models for modification, the Seiko SKX007 and SKX009, are affordable, robust, and versatile dive watches. They have a large modding community and a vast selection of aftermarket parts available.

2. Seiko 5 Sports

The Seiko 5 Sports line is another popular choice for modders due to its affordability and wide range of styles. These watches feature automatic movements, making them great candidates for modification.

3. Seiko Turtle and Samurai

The Seiko Turtle (SRP777) and Samurai (SRPB51) models are also popular for modifications, particularly for those interested in dive watches. They offer a more modern design compared to the SKX series but still have a good selection of aftermarket parts available.

The Modification Process

With the parts at hand, it's time to begin the modification process. Modifying a Seiko watch requires patience, precision, and a steady hand. If you're not confident in your abilities, it's recommended to seek professional assistance. However, if you're up for the challenge, here are the key steps involved in modifying a Seiko watch:

1. Disassembly

Begin by removing the watch strap or bracelet and unscrewing the case back. Carefully remove the movement and dial from the watch case, making sure to store all parts safely.

2. Replace the Crystal

If you're upgrading to a sapphire crystal, carefully remove the old crystal using a crystal press and install the new one.

3. Install the New Dial and Hands

Carefully remove the old dial and hands from the movement, and install the new ones. Make sure to align the hands correctly to ensure accurate timekeeping.

4. Install the New Bezel and Insert

Remove the old bezel and insert it from the watch case, and install the new one. Ensure that the bezel rotates smoothly and aligns correctly with the dial markers.

5. Reassemble the Watch

Carefully reassemble the watch, ensuring that all components are correctly installed and seated. Screw the case back on and reattach the watch strap or bracelet.


Modifying a Seiko watch can be a fun and rewarding project that allows you to create a truly unique timepiece. By choosing the right base model, sourcing quality aftermarket parts, and carefully executing the modification process, you can master the art of Seiko watch modification and create a one-of-a-kind watch that reflects your personal style.
