The 3 Watch Repairs Every Collector Should Do Themselves
The Frustration of the $20 Battery Swap
If you have been collecting watches for any amount of time, you already know the frustration. You buy a fantastic new diver, but the stainless steel bracelet is two links too big. Or your reliable daily quartz watch suddenly stops ticking. Your only option? Driving to the mall, standing at a jewelry kiosk, and paying $20 to a guy who takes your watch behind a counter for five minutes.
The truth about watch collecting is that basic maintenance does not require a Swiss engineering degree. With a few affordable tools and a little bit of patience, you can take control of your collection, save hundreds of dollars a year, and start exploring the deeply rewarding world of watch DIY.
Here are the three basic repairs every collector should learn how to do at home.
1. The Strap Change (Transforming Your Watch)
This is the ultimate gateway into watch DIY. Swapping a stainless steel bracelet for a vintage leather strap or a NATO band completely changes the personality of a watch. It is like getting a brand new timepiece for a fraction of the cost.
What you need:
- A standard Spring Bar Tool: The essential forked tool for compressing pins.
- A fresh set of Spring Bars: Always keep spares on hand. They are spring-loaded and have a habit of flying across the room into the carpet.
The Process: Using the forked end of your tool, you gently compress the spring bar holding the strap between the watch lugs. Once the tension is released, the strap pops right out.
2. Sizing a Metal Bracelet
There is nothing worse than the feeling of a heavy watch sliding up and down your wrist because the bracelet is too loose. Jewelers love charging $15 for this, but it is incredibly simple to do on your own desk.
What you need:
- A 1.6mm Flathead Screwdriver: Perfect for screwed links like those on heavy Oyster bracelets. (Highlight "1.6mm Flathead Screwdriver" and hyperlink it to your screwdriver product page)
- A Basic Casing Cushion: To rest the watch on so you don't scratch the crystal while working.
The Process: Most modern bracelets are held together by either friction pins or tiny screws. Resting the watch case securely on a cushion, you simply back the screws out of the removable links, take out the excess metal, and screw the two sides back together.
3. The Basic Teardown (Opening the Case)
Eventually, every collector wants to see the engine. Whether you need to swap a dead battery on a quartz piece or you are getting ready to attempt your first Seiko automatic movement swap, getting the caseback off safely is a mandatory skill.
What you need:
- A Safe Watch Case Holder: A high-density plastic block with articulating nylon pins is ideal so you don't scratch the steel. (Highlight "Watch Case Holder" and hyperlink to your yellow 4-pin holder product page)
- An XL Jaxa Wrench: A heavy-duty, 3-prong wrench that can expand to fit modern dive watches. (Highlight "XL Jaxa Wrench" and hyperlink to your Jaxa tool product page)
The Process: This is where having the right tool matters. Trying to open a factory-sealed watch in the palm of your hand is a recipe for a slipped tool and a massive scratch across the steel. Clamping the watch into a utilitarian case holder gives you the safe leverage needed for the Jaxa wrench to break the seal safely and easily.
Taking the First Step
You don't need to drop $500 on a professional watchmaker's bench to get started. The beauty of this hobby is that you can build your toolkit slowly, buying only what you need for the project in front of you.
Start small. Grab a spring bar tool, swap out a strap, and see how it feels. You might just find yourself building a custom automatic watch from scratch by next year.
