Ginault 7275 Oscillator

The watch hairspring and balance wheel combined together are referred to as the oscillator. Each hairspring and balance wheel combination has a distinctive center of gravity. Years of experience are required for movement makers to wed two such parts in a perfect marriage, such as that delivered in the balanced oscillator of the Ginault Caliber 7275.

Modern computer aided manufacturing helps achieve nearly error free fabrication as to most parts of a movement, but perfect matching of a hairspring and a balance wheel still must be performed by human hands.

At Ginault, precision manufacturing is our one true pursuit. Almost 30% of our hairsprings and balance wheels are discarded and recycled because they are unable to be suitably matched.

The Powertrain

For an oscillator to deliver the perfect rhythm of 28,800 beats per hour without either gaining or losing time requires a set of gears made with the highest accuracy, with effectively zero tolerance for error in delivering consistent power from the mainspring.

Simultaneously, the materials used in making gears have to be able to endure decades of wear and tear. While most of our fellow watchmakers in Europe and Asia use copper or brass, we have developed our own copper alloy to make the powertrain gears. We call it GC31.

GC31 has strength equal almost to that of steel. It is also antimagnetic. After brushing and polishing, it exhibits a distinctive light, sharing the reflective property of gold.

The Main Plate & The Bridge

Assisted by modern computerized manufacturing techniques, our suppliers make the movement plates and bridges with the exactitude asked by our watch design blueprints. The remaining challenge is hand finishing the chamfers and the internal surfaces to properly receive and seat the red jewels supporting the gears of the powertrain.

Setting jewels is a true test for a watch or a movement maker because the relative precision ultimately affects a caliber’s mean daily rate and isochronism. The skill required in decorating these seats, hidden from view on the movement plate and bridge, is typically mastered only after thousands of hours of training and experience.

As a means of keeping precise time in the present day the mechanical watch is becoming obsolete. The operational limitations imposed by many laws of physics assure that its relative accuracy will be outmatched as against quartz and semiconductors.

Yet mechanical watchmakers continue to thrive by applying their skills and aesthetics in creating beauty through ingenuity and dedication to craftsmanship. And the mechanical watch, with a sensitive movement at its heart, encased in indestructible metal, will continue to be a source of pleasure to its owner out into the unfolding future.
