The GSAR Quartz is made in La Chaux de Fonds, Switzerland to guarantee the highest level of quality and accuracy in manufacturing. Powered by a Swiss made, high torque, 3 jewel ETA FØ6 quartz movement, the GSAR Quartz guarantees you a high degree of accuracy in timekeeping. The ETA FØ6 movement is accurate to -0.3/+0.5 seconds per day and also includes an End of Life (EOL) indicator that will advance the seconds hand once every 4 seconds to inform you that a battery change is needed. Replacement battery is a 371 cell.
The GSAR Quartz uses self-contained Tritium gas tubes to ensure constant visibility in low light situations. A gas tube is placed on each hour marker and each hand. Tritium tubes are self-illuminating gas tubes which contain an isotope of hydrogen, meaning they will not dull down in brightness like normal photo-luminescent paint which requires an external light source to create a glow.
