Dealing with your Casio FT500WC Series not working is a right pain when you need to be on time. While I was living in Cardiff, my own reliable watch stopped ticking just as a grey morning began. It felt quite odd because these analogue models are known for being very sturdy and simple. In this guide, I will share my own story and the easy steps I used to get mine ticking again. You can save a lot of money by trying these quick tips before heading to a high street shop.
Why Is My Casio FT500WC Series Not Working?
You glance down on a grey morning in Cardiff and the second hand is not moving. Or the date window is stuck. That sinking feeling hits because the Casio FT500WC is known for being simple and reliable. The good news is analogue quartz watches usually fail for very predictable reasons.
Flat Battery Is the Top Common Cause
A quartz watch uses a tiny crystal and a battery to keep time. It is a very simple system that works well for years. In the UK, a standard battery usually lasts about two to three years in daily wear.
Signs of a dying battery:
- Jumping hand: The second hand moves in 2-second steps instead of one.
- Complete stop: The watch face looks frozen.
- Weak lume: The glow on the dial looks very dim at night.
Cold weather can also slow down the oil inside the movement. If your watch has been in a cold car, it might stop. A quick check is to warm it up in your hands before you decide to open the case.
Second Hand Jumping Every Two Seconds
If you see your watch “skipping” a beat, do not panic. This is a helpful feature called an end-of-life indicator. It tells you that the battery power is very low. You realistically have about a week or two to get a new one before it stops for good.
Crown Not Fully Pushed In
Sometimes the fix is even simpler. If the crown is pulled out to the time-setting position, the watch will stop to save power. Your watch might appear dead when it is actually just “paused.” Always check this first; it is a fix that takes only a second.
Moisture or Condensation Inside the Dial
Fogging under the glass after a walk in the rain is a bad sign. It means the seals are worn out. This is an early warning that water might be touching the delicate gears inside.
Quick Checks Before Opening the Watch
Before you grab tools at your kitchen table in Sheffield, take a moment. Most FT500WC problems are solved in under 15 minutes without any real cost.
Check the Crown Position
Ensure the crown is fully pushed in against the case. Gently rotate it to confirm it is engaged properly. Sometimes a sleeve or a bag strap can pull it out by mistake.
Listen for Ticking Sound
Hold the watch right up to your ear in a very quiet room. If you hear a faint, steady “tick-tick,” the movement is alive. This means the hands might just be stuck or catching on the glass.
Inspect the Case and Crystal
Look for any fresh cracks in the glass. Check for tiny drops of water under the crystal. Examine the case back to see if the screws or seal look loose.
Battery Replacement Guide for UK Owners
If your Casio FT500WC Series is not working, a battery replacement is usually all it needs. Unlike digital models, this one uses a standard quartz cell.
What Battery Does the FT500WC Use?
This watch typically uses a SR920SW silver oxide battery. You can find these at most UK high street shops or online for about £3 to £8. It is a very common type that lasts well in everyday wear.
DIY vs Professional Replacement
I once replaced mine on a rainy Sunday in Manchester with a basic watch tool kit. It was straightforward but required patience. According to global watch technician Michael Young, “Quartz analogue watches rarely fail mechanically. Power is almost always the issue.” Here is how UK options compare.
| Option | Average UK Cost | Time Required | Risk Level | Best For |
| DIY at Home | £3 to £8 | 20 to 30 mins | Medium | Confident hobbyists |
| Timpson | £12 to £20 | 10 to 15 mins | Low | Quick, professional service |
Step-by-Step Safe Battery Change
- Open the back: Use a small tool to pop or screw off the case back.
- Note orientation: Look at which way the battery (+) faces.
- Avoid touching: Do not touch the copper coils or gears with your fingers.
- Replace cell: Swap the old battery for a fresh silver oxide one.
- Reseat gasket: Ensure the rubber ring is flat and clean.
- Test it: Check the face to see if the second hand is moving again.
Water Resistance and Seal Issues
The FT500WC is a sporty watch, but it is not a deep-sea diver. Water resistance depends entirely on the rubber gasket being in good shape.
Signs of Water Damage
The most obvious sign is fog under the crystal. You might also see tiny spots of rust on the hands or the dial. If the crown feels very stiff when you try to turn it, moisture might be inside the stem.
Can It Be Saved?
Yes, if you act fast. Open the back and leave it in a dry, warm spot. Do not use a hairdryer or a radiator, as high heat can warp the dial. If it still doesn’t work, a professional service might be the only way.
Movement or Gear Train Problems
This is rare for a Casio. However, a very hard knock can knock the tiny gears out of place.
Symptoms of Mechanical Failure
If you have replaced the battery but the watch is still not ticking, the gears might be jammed. You might also see the second hand twitching but not moving forward. If it feels “gritty” when you set the time, the gear train is likely damaged.
Repair vs Replace in the UK
Replacing the whole movement is possible but can be pricey. A new FT500WC usually costs about £30 to £45 in the UK. In most cases, buying a new watch is more practical than paying for hours of repair labour.
Strap and Case Issues That Affect Function
Sometimes it looks like a movement issue, but the fault is external.
Damaged Crown Stem
If the crown feels very loose or falls out, the internal stem is broken. You won’t be able to set the time. This usually requires a pro to fit a new part.
Cracked Resin Case
The resin case is tough but can get brittle in the cold. A crack can let in dust that jams the movement. If you wear your watch while working with tools, a sharp hit can also misalign the internals.
Preventing Future Problems
Quartz watches are very low maintenance, but they are not maintenance-free. A few habits will help yours last for a decade.
Routine Cleaning
Wipe your watch with a clean cloth after it gets wet in the rain. Dry it fully before you put it in a drawer or a box. This stops the screws from rusting over time.
Sensible Battery Change Practice
When you change the battery, look at the gasket. If it looks dry or flat, replace it. Avoid over-tightening the case back, as this can pinch the seal and let water in.
Storage Advice
Keep your watch away from steam in the kitchen or bathroom. Avoid leaving it on a hot radiator. Steady, room-temperature air is the best for quartz movements.
When to Contact Official Support
If your Casio FT500WC Series is not working after a battery swap, it may need a professional look.
Checking Warranty in the UK
Most Casio watches come with a 2-year warranty. Check your box for the paper slip. Keep your proof of purchase, as you will need it to claim a free repair.
Contacting Casio UK
You can visit the official Casio UK service page. They have a main centre that handles all repairs. Turnaround times are usually about two weeks for a standard service.
Expert Advice and Real-World Insight
Horology consultant James Porter explains, “Simple quartz watches are incredibly durable. If they stop, start with the battery before assuming mechanical damage.” In most UK cases, the Casio FT500WC Series not working is resolved quickly and cheaply.

My Personal Experience
Mine stopped on a chilly Newcastle morning. The second hand was jumping every two seconds, then it died. A quick battery swap solved it within half an hour. It is still one of the most reliable everyday analogue watches I own.
Alternative Options: Casio FT500WC Series
I have worn field watches for over 17 years. I used them on hikes, yard work, and daily errands. The Casio FT500WC Series, also called the Forester, is loved for its analog dial, LED light, and soft Velcro strap. But some folks want a bigger case, steel parts, or even more features. Let’s look at the best alternatives.
Casio FT500WC Series vs MW240B
I tried the MW240B for a few months. It feels rugged and easy to read. The large dial helps at a quick glance.
| Feature | FT500WC | MW240B |
|---|---|---|
| Display | Analog + Date | Analog Only |
| Light | LED (Orange) | None |
| Water Resist | 100m | 50m |
| Case Size | 43.9mm | 48mm |
| Strap | Velcro | Velcro |
| Price (avg.) | $25–$40 | $25–$35 |
My Take:
The MW240B is bigger and bold. But it lacks a light and date. The Forester wins for night use and water safety.
Rating: 8.2/10
Casio FT500WC Series vs MWA100H
This model feels more solid. I liked the steel bezel. It adds weight and a premium touch.

|---|---|---|
| Display | Analog + Date | Analog + Date |
| Light | LED | LED Illuminator |
| Water Resist | 100m | 100m |
| Bezel | Resin | Stainless Steel |
| Strap | Velcro | Resin Band |
| Price (avg.) | $25–$40 | $40–$60 |
My Take:
Both give 100m water resistance. The MWA100H feels stronger due to steel. But you lose the soft Velcro strap comfort.
Rating: 8.8/10
Casio FT500WC Series vs Timex Expedition Acadia
I also wore this one on short camping trips. It feels light and simple.

| Strap | Velcro | Fabric |
| Price (avg.) | $25–$40 | $45–$70 |
My Take:
Indiglo lights the full dial. It looks cool at night. But it costs more. The Forester gives better value for money.
Rating: 8.5/10
Casio FT500WC Series vs AW80V
This one mixes analog hands with a small digital screen. I liked it for travel.

|---|---|---|
| Display | Analog | Analog-Digital |
| Light | LED | LED |
| Battery | 3 Years | 10 Years |
| Water Resist | 100m | 50m |
| Strap | Velcro | Velcro/Cloth |
| Price (avg.) | $25–$40 | $30–$45 |
My Take:
AW80V links 10-year battery → less worry → long use. It adds alarms and world time. But water resistance drops to 50m.
Rating: 8.7/10
Casio FT500WC Series vs MRW200H
This is a fan favorite. I wore it near water many times.
| Feature | FT500WC | MRW200H |
|---|---|---|
| Display | Analog + Date | Analog Day-Date |
| Light | LED | None |
| Water Resist | 100m | 100m |
| Bezel | Fixed | Rotary Bezel |
| Strap | Velcro | Resin |
| Price (avg.) | $25–$40 | $20–$35 |
My Take:
The MRW200H feels sporty. The rotating bezel helps track time. But no backlight means low night use.
Rating: 8.6/10
My Final Thoughts on Casio FT500WC Series
If you value comfort, clear time reading, and a simple LED light, the FT500WC Series is a great fit. It suits hikers, students, and daily wear users. However, if you want steel parts, dual time zones, or a full dial glow, you may want another option.
From my experience, Casio links field style → easy dial → quick reading. It links 100m water resistance → swim safe → peace of mind.
