903 St B E
In addition to a fascinating variety of features, the navigation chronograph 903 St B E boasts a functionally reliable dark blue dial with luminous ivory coated hands and indices. Watch lovers appreciate the attention to detail – and the impressive clarity in how the functions are arranged.
The chronograph also impresses those who enjoy performing analogue calculations with a classic slide rule. The positioning of an additional crown at 10 o’clock enables mathematical operations and is used to rotate the slide rule bezel with logarithmic scale. It also allows users to perform multiplication, division and cross-multiplication as well as other useful calculations such as fuel consumption, speed, distance and time. Additional watch features include a chronograph function for measuring and recording periods of time.
