Incredible Girard Perregaux Gyromatic Hf Cosc Observatory Chronometer Mens Watch

1940 - 1960
Description

This is an exceptional and super rare gents observatory grade chronometer wristwatch made by the world renowned premier Swiss maker Girard Perregaux.

The fully automatic Gyromatic 39 jewels hi frequency chronometer movement is regarded as one of the finest ever made during the golden age of Swiss watch making.

It is accurate to +/- 1 second per day and beats at twice the rate of a normal swiss watch at 36000 beats per hour.

This is the calibre 42.1 movement which was directly developed from the calibre 32A chronometer. This one is marked "adjusted 5 positions and temp 36000bph chronometer"

The rotor bridge has the number 421803.indicating that it is calibre 42.1 which has an improved escapement and added hack seconds feature.

It also has a larger barrel and mainspring which gives a longer power reserve than the base 32A chronometer

The chronometer number engraved into the main plate is 43800

There is also the number 9116FA etched into the case betwen the lugs which is the model reference.

It has a very heavy solid stainless steel screw down water resistant case which is in mint condition.

The totally original dial is just glorious, it has its original hands and winding crown with the GP logo on it.

A new glass has been fitted and the case professionally cleaned and polished.

As you would expect the watch is fully marked on the dial, movement and case.

It comes complete with a new premium quality black leather strap and a new presentation box to keep your watch in perfect condition.

This is an extremely rare watch with one of the finest chronometer movements ever made, it is much sought after by collectors.

Girard Perregaux are one of the most exclusive watchmakers in the world and this watch certainly has that understated elegance that whispers class.

The watch case measures 35mm in diameter not including the crown.

Overall this watch is in outstanding original condition.

The watch has just been fully overhauled by our FBHI qualified watchmaker. It has been fully authenticated and found to be a genuine Girard Perregaux in all respects. This watch has been fully and professionally overhauled, the process is highly detailed and meticulous

The watch is stripped down to its component parts and each part is examined under high magnification for signs of wear, any worn parts are replaced with genuine manufacturers original parts. every part is then throughly cleaned in a 3 stage ultasonic cleaning process.

The watch movement is then fully assembled using manufacturer approved oils and lubricants and is carried out in a clean room environment. The watch movement is then checked and adjusted for accurate time keeping. the cases are polished and the watch sealed.

Obviously this is not a cheap or quick process which is why our watches are sometimes a little more expensive than others but you can be assured our watches will give reliable and dependable service and will not require any further attention for many many years.

The watch movement comes with a full 1 year warranty.
