Precision is our Middle Name

Did you Know! - You can greatly Reduce Cost and Increase Reliability by Simply Increasing Precision.

BRG offers ultra-high precision oscillators that often eliminate the need for GPS, radio, or network synchronization.  Ultra-high precision oscillators may also eliminate the need for expensive master clocks, wiring or  radio synchronization.  Many BRG clock models already include ultra-high precision oscillators to immediately reduce cost and increase reliability.  BRG ultra-high precision clocks are factory synchronized to the U. S. Atomic Clock and do not require any further synchronization for the life of the clock.  BRG offers the most precise wall clocks available anywhere, at any price.
