The design principles of an on-board instrument were the inspiration here, entirely in line with the company's tradition. After all, the company founder's first clocks were mechanical airplane clocks for professional use. The 103 St Sa model features a curved, scratch-resistant and anti-reflective coating on both sides 
sapphire crystal glass equipped and has a visible bottom sapphire crystal glass.
