“Most watch problems aren’t mechanical — they’re human.” That’s what the old man told me the day I brought him my first broken Seiko.
He didn’t even look up from his loupe. Just listened to the faint tick, smiled, and said, “Don’t worry. It’s not dead. It’s just waiting for you to understand it.”
That moment stuck with me. Because if you’ve ever built, worn, or fixed a watch, you know — they don’t just break; they communicate. You just have to learn their language.
In this long conversation, we’ll go through 10 problems every modder or enthusiast faces — not as a checklist, but as a story about learning how to listen to your watch.
1. The Watch That Stopped Without Warning
“It was ticking yesterday.” “It’s not ticking now.” “Did I kill it?”
The silence of a stopped watch is unnerving — it feels personal, like you’ve disappointed it.
But most mechanical watches don’t stop because they’re broken; they stop because they’re tired. Manual-wind movements like the Seiko NH35 store power in a spring. When the tension runs out, it rests — like a runner catching breath.
What to Check:
- Power reserve: Wind it 30–40 turns, then listen for a soft hum of life.
- Movement blockage: A small dust speck under the balance wheel can jam it. Use a blower and cleaning cloth before assuming the worst.
- Rotor issue: If it’s an automatic, shake it gently. You should feel a smooth spin, not grinding.
If it still doesn’t tick, don’t panic — it’s rarely fatal. A dislodged gear or sticky oil can pause it temporarily. You can send it for cleaning, or if you’re adventurous, try inspecting with a movement holder and loupe.
Sometimes, the cure is simply understanding that machines need rest too.
2. The Bezel That Spins Too Freely
We’ve all been there — that diver that once had a satisfying click, now spinning like a fidget toy. It’s not the end of the world. It’s just your click spring or bezel gasket calling for attention.
Under that ring lives a simple mechanism: a spring flexing into small case grooves. When it loses tension, your bezel loses purpose.
The Fix:
- Remove the bezel carefully with a taped case knife or bezel remover.
- Inspect the gasket — if it’s flat, cracked, or sticky, replace it.
- Realign the click spring, grease lightly, and reinstall.
It’s amazing how such a tiny part defines an entire watch’s character. You’ll find replacements for Seiko NH35 or SKX bezels easily through Sugargoo, where most microbrand modders quietly shop.
“That click,” the old man said once, “is the sound of precision respecting patience.”
3. Fog Under the Crystal
You glance at your wrist, and there it is — a ghostly mist behind the glass. Moisture. The silent killer of movements.
Water enters through worn gaskets, open crowns, or hasty case closures. But it also reveals something deeper: impatience. Most fogging happens after someone opened their watch too quickly and forgot one step — resealing properly.
The Fix:
- Remove the back using a case opener.
- Pull out the crown, and leave the watch in a dry, warm place for a few hours (rice or silica gel helps).
- Replace every gasket — case, crown, and back.
- Reseal and grease before closing.
Never use heat directly. Moisture is patient — your drying should be too.
You can find watch case gaskets that fit Seiko and NH35 builds on Sugargoo’s verified listings.
4. Misaligned Hands
The hands of a watch are poetry — and even a single misplaced stroke ruins the verse. Misalignment happens during careless assembly, shock impact, or improper hand setting.
It’s a small imperfection, but one you’ll notice every time you check the time — and it’ll haunt you.
The Fix:
- Use a hand remover and setter kit — never pliers or tweezers.
- Remove the crystal or open the case carefully.
- Reset all hands using the “12 alignment method” — when the movement hits midnight, align hour and minute hands exactly at 12.
To practice safely, start with a spare NH35 movement before touching your main build. Because precision, once lost, is hard to forgive.
5. Scratches on the Case Back
Every modder learns this the hard way — you open a watch, and your tool slips. That first scratch always hurts.
But the truth? It’s a rite of passage. No one becomes a craftsman without leaving one small scar behind.
Prevention:
- Use proper case back openers with correct fit.
- Tape your case edges.
- Never work while tired or distracted.
“Polishing hides mistakes,” the old man told me, “but reflection teaches restraint.” Scratches remind you to slow down. And slowing down is the first step to mastery.
6. The Crown That Feels Rough
You turn the crown and feel it — grit, grind, maybe even resistance. That crown is your connection to the movement. If it’s unhappy, the rest soon follows.
A rough crown means dirty threads, dried grease, or a misaligned stem. Ignore it, and you risk stripping the thread or breaking the clutch lever inside the movement.
The Fix:
- Remove the stem and inspect it under magnification.
- Clean with Rodico or soft cloth.
- Grease the thread lightly before reinserting.
Never over-tighten. The feel should be soft, fluid, confident.
For replacement crowns and stems, explore Sugargoo’s watch accessories — they stock NH35-compatible tubes and crowns that fit like OEM.
7. The Strap That Refuses to Stay On
When a spring bar pops out mid-wear, your heart skips faster than the watch ticks. It’s usually caused by worn bars, weak holes, or wrong strap width.
The Fix:
- Replace with fat spring bars (Seiko uses 2.5mm bars for divers).
- Use a proper spring bar tool — don’t improvise.
- Check lug holes — if enlarged, fill with epoxy insert or replace case.
Sometimes, the easiest upgrade isn’t fancy — it’s reliability. Sugargoo’s watch straps collection carries straps pre-fitted for Seiko dimensions.
Because no mod feels right if you’re afraid it might fall off mid-commute.
8. Timekeeping Gone Wild
Too fast, too slow, too unpredictable. You regulate it one week, it misbehaves the next.
Every movement drifts — but when it’s off by minutes, something’s up.
Common Causes:
- Magnetization from electronics.
- Shock impact bending the hairspring.
- Lubrication breakdown inside escapement.
Quick Fixes:
- Demagnetize using a small watch demagnetizer (cheap and effective).
- Regulate using a timegrapher or by adjusting the balance arm slightly — but only if you know what you’re doing.
- Otherwise, send it for servicing — some fixes require trained touch.
To prevent future issues, store your watches in anti-magnetic watch boxes, away from speakers and laptops.
9. Crystal Scratches or Cracks
That moment when you catch light and see a line across your crystal — it stings. Sapphire, mineral, or acrylic — all wear time differently.
Acrylic can be polished. Mineral can’t. Sapphire only hides scratches if coated.
The Fix:
- For light marks: use Polywatch on acrylic.
- For deep scratches or cracks: replace entirely.
You’ll find replacement crystals and tools on Sugargoo, from flat to domed sapphire, AR-coated and pre-sized for NH35 builds.
And next time? Add a watch case protector while working. Because protection is always cheaper than repair.
10. The Watch That Just Feels… Off
This one isn’t technical — it’s emotional. Sometimes your watch works perfectly but feels wrong. The weight’s off. The dial doesn’t connect. The magic is gone.
That’s not a defect. That’s design fatigue.
The solution isn’t fixing — it’s modding. Change something. A new strap, a new case, a new dial. Let your connection evolve.
Use the pieces you already know — your watch cases, movements, tools. You’re not breaking the watch — you’re keeping it alive.
Because watches, like people, grow with attention.
The Lesson Beneath the Steel
After years of modding and mistakes, I realized something: Every watch problem is just time teaching you patience.
A stopped second hand isn’t failure — it’s a reminder to pause. A scratched case is honesty. A fogged crystal is consequence. A loose bezel is a whisper saying, “Next time, take your time.”
We don’t fix watches because they’re broken. We fix them because we love them enough to care about their smallest flaws.
And that’s why, somewhere between steel and soul, this craft feels human.

The Closing Conversation
“So when do you stop making mistakes?” I once asked the old man. He smiled, set down his tweezers, and said: “When you stop rushing. Not when you stop learning.”
That’s watchmaking. That’s modding. That’s life in miniature.
So keep your tools clean, your patience long, and your mind curious. Because time only rewards those who respect its rhythm.
