GYROMATIC by Girard-Perregaux
 
During the 1950s the watch industry saw a growing wave of consumers requesting self-winding wristwatches, as a response to this demand, in 1957, Girard-Perregaux introduced a revolutionary solution, its first self-winding (automatic) wristwatch: the Girard-Perregaux Gyromatic. The Gyromatic was the marketing term (employed for many years) for automatic movements used by Girard-Perregaux; these movements beat at the standard 18,000 bph (beats per hour). The introduction of this movement was very significant in the context of the Girard-Perregaux brand itself, and in the context of technological innovation for the era. “Indeed, horological historians view these early Gyromatic movements as some of the most important ever produced.”
 
The first automatic watches offered by Girard-Perregaux used base movement made by A. Schild (and, later, Peseux), Girard-Perregaux was “dissatisfied” with their performance. So, the brand developed their own winding module: the Gyromatic, which was then added to a blank manually wound movement. The Gyromatic substituted roller-equipped unidirectional clutches for the ratchet (“Gyrotron”) wheels, which made the watch wind smoothly; additionally, each wheel had seven rubies on it to protect the movement from unnecessary wear. The resulting construction was simple, reliable, and efficient. Best of all, the clutch’s compact nature opened the way for slim, sleek, and stylish designs.

“The Gyromatic has since demonstrated its excellence in thousands of Girard-Perregaux models throughout the years.”

Vintage watches are traditionally smaller than today's watches. Men’s watches typically measure between 29-36mm wide (some larger, some smaller) excluding the crown. In the listing details we typically try to do our best to list all pertinent dimensions of a watch. If you don't see it, or we failed to do so, please reach out to us. Women’s watches from the 1900s-1970s were also much smaller than today's offerings. Please also feel free to ask any questions you have pertaining to size. 

We prefer to shoot photographs outside when weather is permitting. However, when we shoot indoors, please be aware that we shoot our photographs inside of lightboxes that are lit with 360 LED bulbs. This indeed magnifies any flaws. Usually, they are much less obvious to the naked eye. Having said that, we never photoshop any of our photography, remove blemishes, etc. We adjust the lighting, when necessary, but what you see is what you are getting, and we take pride in that.  

The condition is pre-owned.   
The item may have some signs of cosmetic wear but is fully operational and functions as intended. 
Please review the photos and feel free to ask any questions you may have.  
 
It will be carefully packed.
