If you’ve ever wanted to customize your own watch or explore the world of modding, the SKX is the perfect place to start.

Why Mod the Seiko SKX?

The Seiko SKX007 and SKX009 models are loved for their reliability and simplicity. But what makes them truly special is how customizable they are. Here are a few reasons why modding the SKX has become so popular:

• Endless Possibilities: With hundreds of aftermarket parts available—from bezels and dials to hands and cases—you can build a completely unique watch.

• Affordable Entry Point: Compared to high-end Swiss divers, SKX models are relatively inexpensive. This lowers the risk of modifying your watch.

• Legendary Status: The SKX has achieved cult status. Modding one lets you keep the iconic feel while personalizing it to your style.

• Robust Platform: Its durable automatic movement (7S26 or NH36 if upgraded) and 200m water resistance make it a solid base for experimentation.

Most Popular SKX Mods

Here are some of the most popular modifications you’ll see in the Seiko modding community:

1. Dial Swap

Swapping out the stock dial is one of the quickest ways to change the look of your SKX. Options include:

• Sunburst dials in blue, green, or red

• California dials (with Roman and Arabic numerals)

• Fully custom printed dials (military, logo-free, etc.)

• Explorer- or Submariner-style dials

2. Hands Upgrade

Pairing your new dial with matching hands makes the build cohesive. Popular hand styles include:

• Mercedes hands

• Snowflake hands (inspired by Tudor)

• Sword or Pilot hands for a military aesthetic

• Lume-filled hands for better visibility

3. Bezel Insert

The bezel is a big focal point, and swapping it out changes the watch's personality. Choose from:

• Ceramic or aluminum inserts

• Pepsi or Coke colorways

• Yachtmaster or GMT-style inserts

• Dual-time bezels for travel use

4. Crystal Upgrade

The original Seiko Hardlex is decent, but many modders opt for a sapphire crystal for its scratch resistance and luxury feel. You can choose from:

• Flat or double-dome sapphire

• Blue anti-reflective coating

• Cyclops magnifier for the date window

5. Movement Replacement

The stock SKX movement doesn’t hack or hand-wind. That’s why many builders swap in the NH36 or 4R36:

• Hacking and hand-winding functionality

• Direct replacement, no case modification needed

• Open heart or skeletonized options for show builds

6. Case and Crown

Some modders go all in and swap the case itself. You’ll find:

• Sterile Submariner-style SKX cases

• Brushed, blasted, or PVD finishes

• Signed screw-down crowns for better water resistance

7. Straps and Bracelets

From vintage-style tropic rubber to Jubilee bracelets and leather rally straps, the strap changes the mood of your mod entirely. Quick-release spring bars make swapping easy.
