The movement:
I can safely say is rarely seen as a well-preserved Longineschronograph movement.
This movement is a composite of 117 brass and stainless steel parts.
an impressive and incredible manual movement of the Longines 19.73N, first made by LONGINES in 1897. The model “N” first made in year 1909.
It is incredible to think of what Longines has achieved in a time when computers were unheard of and all the components inside were carefully considered and planned to create this wonderful masterpiece.
The movement had been completely cleaned and oiled, it works very good and has been tested for a short period of time and shows very good results.
To clean it every one part was disassembled, cleaned and oiled, then placed back very precisely.
The watch movement gain 7- 10 seconds for every 24 hours which is a very good achievement.
For that time a well-working pocket watch gave a difference of 2 - 3 minutes in 24 hours, as hands of watches have been adjusted every day.
The balance running very strong with 18,000 BPH per hour, absolutely perfect condition.
That movement has 21 Jewels, this means that the movement has 21 precious stones (21 rubies), the stones are on the places where it is large friction in order to protect the metal from abrasion.
THIS IS A 30 MINUTE CHRONOGRAPH WITH ONE BUTTON.
One press starts the chronograph, the second press stops it and the third press will reset it.
Inscription on the movement are : " "LONGINES".
The serial number of the movement is : 4222507

It has Arabic numerals, black and red numbers on a white background with two subsidiary dials.
