Hamilton Khaki Aviation Converter Automatic H76615530 100M Men’s Watch

Basic to advanced nautical calculations and conversions become possible without applying difficult formulae into use and running the risk for errors, which could prove fatal at times when you are high above the ground. The critical conversions and metrics take almost no effort; the bi-directional, rotating slide-rule bezel to thank. The H-21-Si automatic chronograph movement is one of the most advanced among anti-magnetics.
