Why Regular Watch Maintenance Matters

A watch is an investment — even an affordable one. Sweat, skin oils, dust, and daily grime accumulate over time, dulling the finish of your case, degrading your strap, and potentially compromising seals. The good news is that basic at-home care is straightforward and takes just a few minutes.

This guide walks you through safe, practical steps to keep your watch looking and performing its best between professional services.

What You'll Need

  • Soft-bristled toothbrush (unused or dedicated)
  • Microfibre cloth
  • Mild dish soap or watch-specific cleaning solution
  • Lukewarm water (only if your watch is water-resistant)
  • Toothpicks or soft cotton swabs
  • Watch spring bar tool (optional, for strap removal)

Step 1: Know Your Watch's Water Resistance Rating

Before applying any water or liquid, check the water resistance rating on your watch's caseback or manual:

  • 30m / 3ATM: Splash-resistant only — do NOT submerge or run water over it.
  • 50m / 5ATM: Light water exposure; avoid running taps and soaking.
  • 100m / 10ATM and above: Safe for more thorough rinsing and cleaning with water.

If your watch has no stated water resistance, treat it as splash-proof only and use a damp cloth rather than direct water.

Step 2: Clean the Case and Bracelet

For metal bracelets and cases (100m+ rated watches):

  1. Remove the strap or bracelet if possible for a more thorough clean.
  2. Mix a small drop of mild soap into lukewarm water.
  3. Dip the soft toothbrush in the soapy water and gently scrub the case, lugs, and bracelet links — especially the crevices where grime builds up.
  4. Rinse briefly under lukewarm running water.
  5. Pat dry immediately with a microfibre cloth, then leave to air dry fully before reassembling.

Important: Always ensure the crown is screwed down or pushed in firmly before any water exposure.

Step 3: Clean the Crystal (Watch Glass)

For light smudges and fingerprints, a dry or slightly damp microfibre cloth is all you need. Use gentle circular motions. Avoid abrasive materials — even paper towels can scratch acrylic or mineral crystals. Sapphire crystal is highly scratch-resistant but not immune, so treat it with care regardless.

Step 4: Care for the Strap

Strap care depends on material:

  • Leather straps: Never soak in water. Wipe with a barely damp cloth, then dry flat in open air. Apply a small amount of leather conditioner occasionally to prevent cracking.
  • Rubber/silicone straps: Rinse with clean water and mild soap. Very durable and easy to maintain.
  • NATO/nylon straps: Can be removed and hand-washed, then left to air dry.
  • Metal bracelets: Clean with the toothbrush method described above.

Step 5: Polish vs. Leave It

Minor scratches on polished case surfaces can be buffed out carefully using a polishing cloth. However, think twice before polishing. Many collectors prefer natural patina and wear marks — they add character and authenticity. Over-polishing can round edges, reduce sharpness, and actually lower a watch's resale value.

When to Seek a Professional Service

At-home care maintains appearance but doesn't replace professional servicing. Take your watch to a qualified watchmaker when:

  • It's running noticeably fast or slow
  • Moisture has gotten inside the crystal
  • The crown feels loose or gritty
  • It's an automatic and hasn't been serviced in 5–7 years

Regular at-home care significantly extends the time between costly professional services, protecting both your watch and your wallet.
