André Belfort: Seconde Volante

A particular automatic movement with flyback has been built in into the “Seconde Volante” from André Belfort. The flyback function of this movement is implemented with 3 hands which start successively 20 seconds of a minute. Reaching the respective end of the display by 20, 40 or 60 seconds, it jumps at the beginning to the zero position, and the display keeps going on the next one of the 3 displays. Additionally to the the flyback the automatic movement has integrated a second time zone which shows independently a second time. The dial is designed with a great accuracy and love for details e.g. through the curved version with guilloche design and makes the Seconde Volante from André Belfort unmistakably unique. Models can be found in polished stainless steel or golden plated each with a black or a silver dial.

Instructions on how to use sliderules on watches

Some wristwatches have a rotary lunette with a scale almost like a sliderule, like e.g. André Belfort Universe. The outer scale on the lunette goes from 10 to 100 and is completed by an inner scale on the dial. These scales make the basic arithmetic operations, multipication and division possible.
But how does the sliderule work?

The highlighted “10” on the inner scale plays an important role.

Basically you accomplish a rule of three. A in relation to B is C in relation to D.

 

How do you multiply two numbers?
Look for your first number of your calculation on the outer scale of the rotary lunette. Turn the lunette until your number is above the highlighted 10 on the inner scale. Now look for your second number on the inner scale on the dial. Now you can read the result of your multiplication on the opposite side of the second number on the lunette.

 

For Example: 9 x 6
Turn the lunette until number 90 (ignore the 0) is above the highlighted 10 on the inner scale. Look for number 6 on the innser scale and read the result above number 6 on the lunette: 54.

 

How do you devide two numbers?
on the outer scale you look for the dividend (the number you would like to devide). Turn this number just above the second number on the inner- the divisor (the number you devide with). Read the results right by the highlighted “10” on the inner scale above the rotary lunette.

 

For Example: 50 : 25
Turn the number 50 on the lunette above the number 25 on the inner scale. Read the result by the hightlighted number 10 on the inner scale. The result is 2 (please ignore the 0)

 

Exception:
If you would like to calculate with a one digdet number please use the decimal number instead an think away the 0. For example for a 7 you take number 70 and just ignore the 0.
