BRG Style 661 Fixed Zone Time Zone Clock — Simple, Accurate, and Ready to Install
By BRG Precision Products | July 22, 2026 | Time Zone Clocks • Fixed Zone
Not every time zone display needs to be reprogrammed. When your locations are fixed — your offices in London, Dubai, Singapore, and New York aren’t moving — BRG’s Style 661 is the clean, simple, cost-effective answer. Fixed zone labels, bar-segment LED time displays, OCXO accuracy that is guaranteed for life, and user-changeable 7-color LEDs in the same professional F5 anodized aluminum frame as every other BRG time zone clock.
The Style 661 is BRG’s most straightforward time zone clock — and its most versatile in terms of zone count, with single-piece models covering 2 to 10 zones and modular configurations extending to 24 zones in 1.8″, 2.5″, and 4.0″ LED heights. If you know which cities you need and they’re not going to change, the Style 661 delivers everything you need without the cost of a programmable display.
Fixed Zone vs. Programmable — Which Do You Need?
The key question is simple: will your time zones ever change?
Choose the Style 661 if your city locations are fixed. The zone labels are white vinyl, applied at the factory with the city names you specify. The clock ships ready to hang and plug in. Lower cost, immediate availability from in-stock inventory, same OCXO precision, same 7-color LEDs, same aluminum frame.
Choose the Style 6610 or 6673 if you need to change which cities or zones are displayed over time — for operational flexibility, changing command structures, or rotating mission requirements. Programmable dot matrix labels can be changed any time via IR remote or computer interface.
Key Features
OCXO Oscillator — Accurate for Life
Every Style 661 is factory synchronized to the U.S. Atomic Clock and equipped with BRG’s OCXO oscillator, accurate to ±1 second over 20 years. No adjustments, no sync wires, no radios, no GPS, no network. Accurate the day it ships and for the life of the clock.
User-Changeable 7-Color LEDs
Even though the Style 661 has fixed zone labels, the LED color for each zone is fully user-changeable at any time using the included IR remote. Change one zone, several zones, or all zones to Red, Blue, Green, Yellow, Magenta, Cyan, or White. Highlight a hot zone, make Zulu stand out, or update the display color anytime. 3X more LEDs than competing products.
White Vinyl Zone Labels
Zone labels are white vinyl, applied below each time zone at the factory with the city names you specify at the time of order. Labels are clear and professional, visible from viewing distances appropriate to the LED size selected.
In-Stock Models Ship in 5 Business Days
Many Style 661 models are stocked in inventory and ship within 5 business days of receiving the time zones. Custom orders typically ship in 2 weeks. Check the live product page for current in-stock availability.
Modular Configurations Up to 24 Zones
For installations requiring more than 10 zones, BRG offers modular Style 661 configurations that link multiple sections into a single continuous display, covering 10 through 24 zones in 1.8″, 2.5″, and 4.0″ LED sizes.
BRG F5 Anodized Black Aluminum Frame

Frequently Asked Questions
Q: Can I change the zone labels on a Style 661 after purchase?
The Style 661 uses fixed white vinyl zone labels set at the factory. The labels themselves are not field-reprogrammable. If you need to change which cities or zones are displayed in the future, consider BRG’s Style 6610 or 6673 programmable series, which use dot matrix LED zone labels changeable at any time via IR remote.
Q: Can I still change the LED color on a Style 661?
Yes. Even with fixed zone labels, every Style 661 includes user-changeable multi-color LEDs. Change any zone’s color to Red, Blue, Green, Yellow, Magenta, Cyan, or White at any time using the included IR remote.

Yes. Multiple Style 661 models are available through GSA Multiple Award Schedule contract # 47QSMS26D002K, SIN 339950. BRG sells exclusively direct — no authorized third-party resellers.
