BRG DuraTime 2.4 GHz Wireless Synchronized Clock System — Designed to Never Fail
By BRG Precision Products | August 3, 2026 | Synchronized Clocks • Wireless Systems
BRG makes a bold claim about the DuraTime 2.4 GHz Wireless Synchronized Clock System: it is the only clock system designed to never fail. That confidence comes from a combination of built-in redundancy, a self-healing mesh communications network, and OCXO oscillators in every single clock — making the DuraTime the most reliable synchronized clock solution available, at any price.
Used in healthcare facilities, universities, schools, government facilities, financial institutions, military bases, and wide-area campus environments, DuraTime keeps synchronized time everywhere in your facility — all the time — even when individual components experience issues.
Why “Designed to Never Fail”?
Primary and Backup Master Clocks
Every DuraTime system ships with both a primary and a backup master clock. If the primary experiences any issue, the backup takes over instantly — automatically, with zero downtime and zero manual intervention. This built-in redundancy is standard in every DuraTime system, not an upgrade.
Self-Healing Mesh Network
Every DuraTime secondary clock both receives and re-broadcasts time updates to neighboring clocks. This mesh architecture means there is no single point of failure in the signal path. If any clock or transmission path is interrupted, the network automatically routes around it. No configuration is required — the system heals itself.
OCXO Oscillator in Every Clock
Unlike systems that use low-quality internal oscillators and rely entirely on wireless sync, every DuraTime clock — including every secondary clock — has BRG’s OCXO oscillator accurate to ±1 second over 20 years. Even if a clock loses its wireless signal entirely, it continues displaying correct time independently for the life of the clock.
AES 128-Bit Encryption
All DuraTime communications use AES 128-bit data encryption throughout the system. No FCC license is required. DuraTime operates on the 2.4 GHz ISM band using Direct Sequence Spread Spectrum — a completely separate channel plan from Wi-Fi, with no interference between the two systems.
NTP and GPS Simultaneously
DuraTime master clocks support NTP and GPS time sources simultaneously for maximum accuracy. IPv4 and IPv6 Ethernet protocols are supported. Wireless GPS antenna options are available for installations requiring GPS-disciplined time without a reliable network time source.
Unlimited Scalability
From a 2-clock installation to a multi-building campus with thousands of clocks, DuraTime scales without limit. Small systems require no site survey. Turn-key installation is available for large deployments.
What DuraTime Can Synchronize
DuraTime synchronizes far more than just wall clocks. In addition to 2.5″, 4″, 8″, and 12″ LED digital clocks, analog clocks, and LCD clocks, DuraTime can also drive:
Wireless tone generators for alarms and period bells • Wireless audio players for announcements • Wireless relay outputs to drive mechanical bell systems • Julian calendar clocks • Alphanumeric display clocks • Large outdoor digital clocks (IP65, NEMA enclosures available)
Frequently Asked Questions
Q: Does DuraTime interfere with Wi-Fi?
No. DuraTime uses different channels and frequency planning than Wi-Fi, even though both operate in the 2.4 GHz band. DuraTime uses Direct Sequence Spread Spectrum (DSSS) and does not share frequency spectrum with Wi-Fi or interfere with cellular communications.
Q: What happens when the master clock fails?
DuraTime includes both a primary and backup master clock. The backup takes over automatically with no downtime. Every secondary clock also has an OCXO oscillator, so it continues showing correct time independently even without any master clock signal.
Q: Is DuraTime available on GSA contract?
Yes. DuraTime 2.4 GHz Wireless Synchronized Clock System components are available through GSA Multiple Award Schedule contract # 47QSMS26D002K, SIN 339950. BRG sells exclusively direct — no authorized third-party resellers.
