The chain is fine...but I ordered the wrong size. Nine links of the chain I ordered equals six of the size I wanted. My error...
How can I straighten out the springs? I can't use them coil uo as is.
Watch repair tool kits from HomeDIYer give you everything you need to handle battery swaps, strap changes, bracelet sizing, and case back service at home — without a trip to the jeweler or a repair shop markup. Whether you're cracking open a Casio for a fresh battery or servicing a Rolex with a threaded screw-back, the right kit makes the job clean, fast, and repeatable.


























The 147-piece Watch Repair Kit is the most practical starting point for anyone new to watch servicing. It bundles a case back opener, link pin remover, spring bar tool, case cushion, and multiple precision screwdrivers into a single organized case. Every tool you need for a battery swap, strap change, or bracelet sizing job is in one place — no hunting through drawers mid-repair.
Opening a watch case cleanly is the first skill every home watchmaker needs. Snap-back cases require a pry tool or friction ball at the case notch. Threaded screw-back cases — standard on Rolex, Tudor, and most Swiss sport watches — need an adjustable wrench-style opener. Our Watch Back Case Opener Screw Wrench Kit and the dedicated Watch Case Opener 5537 cover both styles reliably.
Spring bars are the small spring-loaded pins that hold a strap or bracelet to the watch case lugs. Our stainless steel spring bar sets come in 270-piece (8–25 mm) and 360-piece (10–27 mm) configurations, covering virtually every watch size from slim dress watches to oversized dive models. Keeping a full assortment on hand means you're never stuck waiting on a single size.
After a battery change or movement service, the case back needs to be reseated evenly. A watch press set applies centered, controlled pressure using interchangeable dies matched to the case diameter. Our Watch Press Set includes 12 snap-on fitting dies and moulds. The same press handles crystal fitting — a task that's nearly impossible to do cleanly by hand.
Watch screws are small enough that a standard household screwdriver will strip them on the first attempt. The 25-in-1 and 63-in-1 precision screwdriver sets include fine-tip bits sized for the miniature Phillips, flathead, and Torx screws found in watch movements, case backs, and bracelet links. The rotating cap and ergonomic handle give you the tactile control needed to apply just enough torque.
Not every watch uses the same case back format. The 19-piece Watch Repair Tool Back Case Opener Kit provides a range of wrench heads and adapters to handle case backs across multiple brands and case diameters. It's the right choice when you're servicing watches from different manufacturers — or when you won't know what you're dealing with until the watch is in your hand.

Watch repair tool kits at HomeDIYer are priced to make professional-grade home servicing accessible without the trade markup. The 147-piece kit delivers the same functionality as bench tools sold to certified watchmakers at a fraction of the cost.
Every kit in this collection is curated to include the tools you actually need for the task. The 147-piece set, the 19-piece opener kit, and the press set with 12 dies are all organized and complete out of the box — no separate purchases required to get started.
Spring bar size ranges, die counts, bit types, and brand compatibility details are listed clearly on every product page. You won't discover a size gap or missing adapter after the package arrives.
Orders ship from multiple U.S. warehouse locations, which means shorter transit times for most customers. When your watch needs a battery and you're waiting on tools, speed matters.
HomeDIYer was built for people who take their projects seriously — whether that's a home renovation, a garden build, or a watch sitting open on the workbench. Our watch repair tool selection reflects the same standard we apply across every category: tools that perform as described, specs you can verify, and a catalog that doesn't waste your time with products that cut corners. When you order from HomeDIYer, you're buying from a store that understands what it means to actually use the tools you sell — and that holds every product to that standard before it makes it into the catalog.
Run through this quick checklist each season to keep your watch repair tools in top condition and avoid damaging the watches you work on:
A complete watch repair tool kit typically includes a case back opener (for both snap-back and screw-back cases), a spring bar tool, link pin remover, case cushion or holder, and a set of precision screwdrivers. Our 147-piece kit bundles all of these into one organized case, making it the most practical starting point for home watch servicing.
Yes. The 147-piece Watch Repair Kit is specifically designed to be beginner-friendly. Start with a battery swap or strap change — both are low-risk tasks that build confidence before moving on to more involved repairs.
A snap-back case pops off with a pry tool at the case notch. A screw-back case must be turned counterclockwise with a wrench-style opener. Our kits include tools for both types, and the Watch Case Opener 5537 is designed for Rolex and Tudor screw-back cases.
Measure the lug width of your watch. Common sizes are 18 mm, 20 mm, and 22 mm for men's watches, and 14 mm or 16 mm for women's watches. Our 270-piece set covers 8–25 mm and our 360-piece sets cover 8–27 mm.
Yes. The Watch Case Opener 5537 is purpose-built for Rolex and Tudor models with threaded screw-back cases. Its adjustable jaws grip the case back notches securely without slipping or scratching.
Select the die that matches your case back diameter. Place the watch face-down on the case cushion, center the die over the case back, and apply firm even pressure until you hear a click. Do not use excessive force.
Find the directional arrow on the bracelet link, align the pin punch, and tap gently until the pin slides out. Reinsert from the opposite direction to reassemble. The 147-piece kit includes a link pin remover for this task.
Yes. The 25-in-1 and 63-in-1 precision screwdriver sets include fine-tip bits for the miniature Phillips, flathead, and Torx screws found in watch movements, case backs, and bracelet links.
The 270-piece set covers 8–25 mm widths. The 360-piece sets extend to 10–27 mm, useful for larger sport or dive watches. If you service a wide variety of watches, the 360-piece set gives more flexibility.
