Base 3 nerd watch
· v3.1
About
Can you read the time before your friends can? Challenge yourself to think in base 3 — the number system with only three digits: 0, 1, and 2.
Every number on this watch face is displayed in ternary (base 3). Just like normal numbers, the largest value is on the left. Each digit position is worth 3 times more than the
one to its right:
- Leftmost digit = highest value
- Each step right = divide by 3
- Rightmost digit = 1 (3⁰)
To read a number, multiply each digit by its position value and add them up. For example, 14:45 looks like 112:1200 — where 1×9 + 1×3 + 2×1 = 14, and 1×27 + 2×9 = 45.
The watch displays:
- Time — hours and minutes
- Date — month and day
- Battery — percentage remaining
- Steps — daily step count
An optional "cheat mode" overlays the decimal values in small text — great while you're still learning.
