Basic Time Zone Clocks Aren’t That Basic: Meet the Style 661 & Style 300
By BRG Precision Products | July 1, 2026 | Time Zone Clocks
When customers ask us for our most basic time zone clock, we point them to the Style 661 and Style 300. They’re our entry-level fixed zone displays — no touchscreen remote, no networked scheduling, no frills. But “basic” at BRG doesn’t mean stripped down. Open one up and you’ll find the same core technology that goes into our most expensive precision clocks.
That’s not a coincidence. Every BRG time zone clock, from the simplest 2-zone display to the most elaborate 24-zone modular wall, is built on the same foundation of accuracy and durability. The difference between “basic” and “premium” in our lineup comes down to programming flexibility and display options — not the quality of what’s inside the case.
What's Actually Inside a "Basic" BRG Clock
OCXO Oscillator — Accurate to ±1 Second Over 20 Years
This is the same oven-controlled crystal oscillator standard across BRG's entire time zone clock line. Every Style 661 and Style 300 display is factory synchronized to the U.S. Atomic Clock in Fort Collins, Colorado before it ships. No GPS antenna, no NTP connection, no master clock, and no manual adjustments — ever. The clock simply stays accurate for the life of the product.
User-Changeable Multi-Color LEDs
Both series let you change the color of one zone, several zones, or all zones with the included infrared remote control. Choose from seven colors — red, blue, green, yellow, magenta, cyan, or white — and reprogram them anytime your needs change. Highlight an operations zone in a different color, make Zulu time stand out, or simply switch away from red LEDs whenever you want. This feature is standard, not an upgrade.
Available in 1.8″, 2.5″, or 4.0″ LED Heights
Viewing distance scales with LED size: 1.8″ displays are readable from 40 feet, 2.5″ displays from 75 feet, and 4.0″ displays from 100 feet. Whether the clock is going on a wall across a small office, or high on a wall in a large operations room, there’s a size that fits the space.
Black Brushed Anodized Aluminum Frame
Every Style 661 and Style 300 ships in BRG’s F5 anodized black aluminum frame — the same housing used across BRG’s time zone display line. It’s built to hold up in continuous, around-the-clock commercial and government use, not a consumer-grade plastic shell.
Smoked Polycarbonate Lens
The smoked lens protects the LEDs while making the seven available colors stand out clearly, even in well-lit rooms. It’s a small detail that makes a real difference in legibility.
Style 661 vs. Style 300: What's the Difference?
If both series share the same core technology, what actually separates them? It comes down to orientation and zone count.
| Feature | Style 661 | Style 300 |
|---|---|---|
| Orientation | Horizontal — zones arranged side by side | Vertical — zones stacked top to bottom |
| Zone Range | 1 to 10 zones (up to 24 in modular configurations) | 2 to 10 zones |
| LED Sizes | 1.8″, 2.5″, or 4.0″ | 1.8″, 2.5″, or 4.0″ |
| Best For | Wide wall spaces, long horizontal runs, operations centers | Narrow wall spaces, columns, lobbies, hallways |
In short: if your install space is wide, the Style 661 makes better use of it. If your space is tall and narrow — a column, a slim wall segment, a hallway — the Style 300’s vertical stack of zones is the better fit. Both are built around the same internal technology, so the choice is really about your wall, not about which clock is “better.”
Why "Basic" Doesn't Mean "Limited"
It’s tempting to assume an entry-level product cuts corners somewhere. With BRG’s Style 661 and Style 300, it doesn’t. Here’s what you’re not giving up by choosing the simpler models:
Accuracy — The OCXO oscillator is the same precision component used in BRG’s most advanced clocks. A Style 661 keeps time exactly as accurately as a Worldview display costing many times more.
Build Quality — The F5 anodized aluminum frame is BRG’s standard housing, not a downgraded enclosure reserved for entry-level products.
Color Flexibility — User-changeable multi-color LEDs are standard on every BRG LED digital clock, including the 661 and 300 series. There’s no “color upgrade” tier to pay for.
What you are giving up, by design, is on-the-fly reprogrammability of zone labels and the touchscreen Time Commander remote workflow found on BRG’s programmable series like the Style 6610. If your zones rarely or never change — say, a fixed set of regional offices or military commands — that’s not a limitation. It’s simplicity that matches the application.
Who Should Choose a Style 661 or Style 300?
These models are an excellent fit for any facility that needs reliable, accurate, multi-zone time display without the need to frequently reconfigure which locations are shown:
Corporate Offices — Display the time at headquarters alongside branch offices or international partners in a conference room or lobby.
Operations & Command Centers — Track local time alongside Zulu/UTC and other operational zones, with the option to color-code critical zones for quick visual reference.
Schools & Universities — Show time across multiple campuses or partner institutions in a hallway or administrative office.
Government & Military Facilities — Both series are available through BRG’s GSA Multiple Award Schedule contract, with options for ATO military day codes, ISO8601 work week, Julian date, and military shipping codes.
Frequently Asked Questions
Q: Can I change the zone labels on a Style 661 or Style 300 after purchase?
Zone labels are printed on white vinyl and applied to the display. If your zones change, the vinyl labels can be replaced and the corresponding zone reprogrammed using the included IR remote. For applications that need frequent zone relabeling, BRG’s programmable series (such as the Style 6610) uses digital zone labels instead of vinyl.
Q: How many zones can a Style 661 or Style 300 display?
The Style 661 ranges from 1 to 10 zones in its standard configurations, with modular configurations available up to 24 zones. The Style 300 ranges from 2 to 10 zones. Both are available in 1.8″, 2.5″, or 4.0″ LED heights.
Q: Do I need a network connection or GPS antenna for these clocks to stay accurate?
No. Both the Style 661 and Style 300 include the OCXO oscillator as standard, factory synchronized to the U.S. Atomic Clock before shipping. No GPS, NTP, or master clock connection is required for the life of the display.
Q: What happens to the time and configuration during a power outage?
Time and configuration settings are maintained during shipping and power outages. When power is restored, the display resumes showing the correct time without any reprogramming.
Q: Are the Style 661 and Style 300 available on GSA contract?
Yes. Both series are available to U.S. federal government customers through GSA Multiple Award Schedule contract # 47QSMS26D002K, SIN 339950. BRG sells exclusively direct — there are no authorized third-party resellers for BRG products on GSA Advantage or any other government procurement platform.
Accurate for life. Built to last. Priced for every budget.
