What is the minimum tool set to start modding?
A spring bar tool, a case opener, a movement holder, hand-setting tools, tweezers, and a loupe will handle most beginner mods. Add a case press for clean closes and a demagnetizer as cheap insurance.

Watch Modding & Repair Tools
A practical guide to the watch modding and repair tools that matter. Skip the giant 150-piece watch repair kit — here is the focused set that handles most mods, plus the specialist tools worth adding later.
Do you need a full watch repair kit to mod a watch?
No. Most cheap watch repair kits are mostly filler. A small set of quality watch modding tools will get you through strap swaps, crystal changes, and dial-and-hands work — which covers the vast majority of beginner mods. Buy the few things you will actually use, then add specialist tools when a specific project needs them.
The essential watch modding tools
- Case opener or case knife — to open snap-on or screw-down casebacks
- Case press — to seat the caseback and crystal evenly without cracking anything
- Movement holder — keeps the movement steady for dial and hands work
- Hand-setting tools — remove and press on hands without bending them
- Spring bar tool — for straps and bracelets, used on every build
- Precision tweezers and a loupe — for handling and inspecting small parts
- Dial protector and Rodico putty — guard the dial and lift dust and fingerprints
Specialist and cleaning tools
- Watch demagnetizer — a $10–15 fix for a magnetised movement running fast
- Watch ultrasonic cleaner — for cleaning cases, bracelets, and parts
- Watch polishing supplies — for removing light case scratches
- Bezel removal tool — to lift bezels and inserts without marking the case
- Timegrapher (or phone app) — to check accuracy on mechanical builds
Buying advice
A solid starter set from a known supplier runs about $40–80 — a one-time cost that pays off across many projects. Avoid the temptation of the biggest box; quality on the few core tools beats quantity. Add a case press, demagnetizer, and loupe early, and pick up model-specific tools as you go.

Frequently Asked Questions
What does a watch case press do?
A case press uses matched dies to seat the caseback and crystal evenly, giving a clean, gasket-sealed close without cracking the crystal — something you cannot do reliably by hand.
Do I really need a watch demagnetizer?
If a mechanical watch suddenly runs very fast it is often magnetised. A demagnetizer fixes that in seconds and costs $10–15, so it is worth owning even just as insurance.
