The TSAR is handmade in La Chaux de Fonds Switzerland to guarantee the highest level of quality and accuracy in manufacturing. Inside the TSAR is a Swiss made, 3 jewel ETA F06 high torque quartz movement. The TSAR uses self contained Tritium tubes to ensure constant visibility in low light situations. A tube is placed on each hour marker, each hand and uses MaraGlo for the 12 hour bezel marker. Tritium tubes are self illuminating 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
