The Pyramid DIG-4B and DIG-6B are the same commercial LED wall clock at heart — standalone, 4-inch red digits, readable to 250 feet, made in the USA. The only real difference is how many digits they show. Here’s the quick answer, then a full side-by-side.
Quick answer
Choose the DIG-4B if you only need hours and minutes (HH:MM). Choose the DIG-6B if you also need seconds (HH:MM:SS) — for labs, gyms, dispatch, broadcast, and testing.

When to choose the 4-digit DIG-4B
If hours and minutes are all your space needs, the DIG-4B is the simpler, lower-cost pick. It’s ideal for warehouses, break rooms, gyms, and classrooms — anywhere people just need to see the time clearly from across the room. See our guide to large digital wall clocks for warehouses.
When you need the 6-digit DIG-6B (seconds)
If your work depends on the seconds, choose the DIG-6B. Labs, testing centers, gyms running intervals, broadcast/AV, and dispatch all benefit from a shared to-the-second display. More on that in our guide to digital wall clocks with seconds.
Price & volume pricing
Both clocks have automatic volume discounts that apply at checkout:
- DIG-4B: 1 = $249 · 3–5 = $242 · 6–11 = $236 · 12+ = $229
- DIG-6B: 1 = $289 · 3–5 = $279 · 6–11 = $272 · 12+ = $269
Net-30 terms are available for verified facility, government, and GSA accounts.
Both are standalone and made in the USA
Neither clock needs a master clock or network — plug into a 110V outlet and it keeps its own time. Both also offer optional RJ45 sync to Pyramid master-clock systems if you ever want to network them. Browse both in our standalone digital clocks category.
Frequently asked questions
Digit count. The DIG-4B shows hours and minutes (HH:MM); the DIG-6B adds seconds (HH:MM:SS). Everything else – 4-inch digits, 250-ft readability, 12/24-hour, battery backup – is the same.
Yes. Both use 4-inch numerals readable up to 250 feet; the DIG-6B is simply wider to fit two more digits.
No – it’s a four-digit clock (HH:MM). If you need seconds, choose the six-digit DIG-6B.
Usually the DIG-4B, unless you’re timing intervals or need seconds – then the DIG-6B.
