Custom Watches: How to Mod a Unique Timepiece

Whether you’re looking to create a one-of-a-kind timepiece or upgrade your existing watch, this guide will provide you with the knowledge and resources necessary to make your dream watch a reality. We’ll start by exploring the different watch modifications and customisation types, from swapping out parts and replacing components to refinishing and engraving. 

We’ll also look at the mod parts and materials you’ll need for your project and the key steps you should take to ensure successful completion. So, if you’re ready to build your dream watch, let’s begin!

Watch Modding: What Is It?

Watch modding is replacing the watch’s original components with new ones. Although these components are frequently bought as upgrades, they can also be taken out of one eye and put into another if compatible. Modifying breathes new life into old timepieces and makes it possible to “upcycle” used components from damaged watches. 

Which Watches Can Be Modded? 

Any watch can be modified! The only question is where to look for the components. For instance, Seiko and Casio watches, particularly the SKX/SRPD family of sports watches and the still-relatively-new G-Shock GA2100 “Casio Sk” series are the most often used watch mod platforms. 

While alternatives for other brands, like Citizen, have increased recently, it will take some time before it catches up to Seiko, which has the largest mod community. Even the most expensive luxury timepieces, such as Rolex watches, can be modded. Adding aftermarket bezels or dials with shimmering, sparkling, or vibrant hues is one of the most common Rolex modifications.

Which Parts Can Be Modded? 

Although practically every watch component can be modified, the key parts that make up the watch’s face are some of the most frequently upgraded and replaced parts. On the majority of automatic timepieces, this includes: 

  • Dial 
  • Hands
  • Bezel insert
  • Chapter ring

Improving or swapping out a watch’s external parts is also feasible. These pieces consist of the following: 

  • Case
  • Bezel 
  • Crown
  • Caseback 
  • Strap or bracelet

Finally, it is possible to upgrade the movement’s parts (or the entire movement! ), for the daring modders more at ease with peering inside a watch’s beating heart. The following components: 

  • Day wheel
  • Date wheel 
  • Stem
  • Rotor

Where Can You Mod a Watch? 

Watch modification is an exciting and creative way to customise and make your watch uniquely yours. Whether you’re looking to turn a brand-new watch into something special or to restore an old favourite, there are plenty of options for modding your watch. 

Your Local Watch Shop

Your local watch shop is a great place to start when you’re looking to mod a watch. Many watch shops have an in-house watchmaker who can help you customise your watch with aftermarket parts, such as new dials, bands, hands, and bezels. The watchmaker can also offer advice on what type of parts are best suited for your particular watch and explain the pros and cons of different modding options.

Online Modding Services

If you’re unable to visit a watch shop in person, plenty of online modding services are also available. Some companies specialise in customising watches, offering various services, such as changing the case, custom Seiko dials, bezels, and bands, replacing watch hands, and adding sapphire crystals. These services can be expensive, so it’s important to research and ensures you’re getting the best deal.

DIY Modding

If you’re looking for a more hands-on approach, you can also try modding your own watch. Plenty of tutorials and instructional videos online can help you get started. You’ll need basic tools such as screwdrivers, tweezers, a watch case opener, and any parts you may need to complete the mod. 


No matter where you decide to mod a watch, it’s important to research and ensure you’re comfortable with the process. Modding your watch can be an exciting and rewarding experience, so don’t hesitate to explore all the possibilities.
