I have tried every “Focus Timer” on the App Store. Forest, Session, Pomofocus, generic countdowns: they all share the same fatal flaw: They live on my phone.
To check how much time is left in my creative writing sprint, I have to wake up a device that contains my email, the endless possibilities of AI, and countless notifications. It is similar to trying to be gluten-free while holding a soy sesame bagel. The tool for focus is housed inside the machine of distraction.
Enter the Casio AE-1300WH.
It looks like the famous Casio Royale (AE-1200), but the internals are completely different. While the Royale is designed for “travelers” (world maps), the 1300 is designed for referees and coaches. It is an interval training engine. And by accident, it is the perfect wrist-mounted Pomodoro machine.
The Specs
- MSRP: $39.95 (purchased for $20 on eBay)
- Case Size: 45 × 42.1 × 12.5 mm

Impact on Attention & Creative Workflow
Impact on Attention
By transferring the timing cycle to your wrist, you create a physical boundary between your work and your distractions. You can leave your phone in the other room. The watch does one thing, track blocks of time, and it does it without ever asking you to “rate the app” or look at an ad.
The genius of this watch is the “Referee” visualizers, the three circular eyes at the top of the display. On most Casios, these are just decoration. On the 1300, they graphically fill and empty to show elapsed time. This lowers mental effort. When I am deep in a writing flow, I might not want to read numbers (“14:22 remaining”) and do math. I just want to glance and see a shrinking pie chart. It taps into the primal brain, keeping the flow state while keeping me on track.
Pros & Cons
The “Interval” Engine
Unlike almost any other cheap digital watch, this model allows you to program a specific loop of timers (e.g., 25 minutes + 5 minutes) that repeats automatically. It is a set-it-and-forget-it Pomodoro technique.
Visual Feedback
The three circles provide graphical data representation. It turns time into a shape, not just a number, which can be surprisingly effective for pacing yourself during creative tasks.
The Reliability Factor
The watch runs for 10 years on a $5 battery. It is always on. It never needs a software update. It respects your attention by being boringly reliable.
No Vibration
The watch beeps. If you are in a library or a meeting, you cannot use the timer without others hearing it. (For silent alarms, look at the Casio W-735H…review coming soon!).
Resin Glass
The screen is acrylic. It will scratch relatively easily compared to mineral glass, though a 5-minute polish with Polywatch should fix it right up.
Complex Setup
The “Referee” functions are powerful but require reading the manual (see instructions below). It is not “pick up and play” like a basic G-Shock.
The Final Verdict
The Casio AE-1300WH takes a process that usually fragments our attention, checking the time, and turns it into a background process. For the price of two months of a “Premium” productivity app subscription, you get a device that will guard your focus for the next decade.
I rate this watch a Distraction Level of 5% for two reasons. First, the “Referee” wheels are constantly animating, which can be mesmerizing to the point of distraction if you are prone to staring. Second, the beep is loud. It will absolutely shatter your concentration, but isn’t that the point of time boxing?
A final word of warning: for some. this watch will feel aggressive. Seeing time physically disappear on your wrist induces a state of flow. For others, it creates anxiety. If you find countdowns stressful rather than structured, the spinning wheels on the AE-1300WH might feel like a tiny wrist-mounted timebomb.
But if you thrive on structure, this is the best $25 you will ever spend to help keep you on track.
Oh, the Casio just beeped, time to move on to my next project!
How-To: Time-Interval Setup Guide
1. Enter Interval Mode
Press the Mode Button (Bottom Left) until you see INT at the top of the screen.
2. Set Interval 1 (5 Minutes)
- Hold Adjust (Top Left) until the numbers flash.
- Press Start (Bottom Right) to increase minutes to 05:00.
- The Crucial Step: Press Adjust (Top Left) once. The numbers will stop flashing.
- Now that it is saved, you are ready to move to the next slot.
3. Set Interval 2 (3 Minutes)
- Press Light (Top Right) to scroll to INT 2.
- Hold Adjust (Top Left) until the numbers flash.
- Press Start (Bottom Right) to set this to 03:00.
- Press Adjust (Top Left) once to save (stop flashing).
4. Set Interval 3 (5 Minutes)
- Press Light (Top Right) to scroll to INT 3.
- Hold Adjust (Top Left) until the numbers flash.
- Press Start (Bottom Right) to set this to 05:00.
- Press Adjust (Top Left) once to save.
5. Clear Interval 4 (The “Stop” Wall)
- Press Light (Top Right) to scroll to INT 4.
- Ensure this reads 0:00. If it has time on it, hold Adjust and clear it to zero.
- Setting this to zero tells the watch that the sequence ends after Interval 3.
6. Activate the Loop (Auto-Repeat)
- While on the main INT screen (not flashing), hold Adjust (Top Left) briefly to enter edit mode, then press Mode (Bottom Left) to cycle settings until you see the Auto-Repeat indicator (usually a circular arrow).
- Press Start to toggle it ON.
- Press Adjust to exit.
- Now, when you start the timer, it will run 5 -> 3 -> 5, then automatically loop back to the beginning.
FAQ
Can I set this to loop for 25 minutes work and 5 minutes rest? Yes. You can set Timer 1 for 25 minutes and Timer 2 for 5 minutes, and set “Auto-Repeat” to ON. The watch will beep at the end of 25, immediately start counting down 5, beep again, and repeat the cycle.
Is the alarm loud? It is a standard digital “beep.” It is audible in a normal room but might be missed in a loud gym or with noise-blocking headphones. It is not silent/vibrating.
How does this compare to the “Casio Royale” (AE-1200)? They share the exact same case and strap, so you can swap parts between them. The AE-1200 is for travelers (World Map); the AE-1300 is for workers and athletes (Timers).
Is it durable? While not a G-Shock, the 100M water resistance means you can swim and shower with it. It is tough enough for daily abuse, though the face will pick up scratches over time.
