While Hublot is renowned for its fusion of luxury and avant-garde design, often incorporating in-house movements, the brand's early history and certain models feature a crucial component: the ETA Valjoux 7750 movement. This article delves into the significance of the Valjoux 7750 within the context of Hublot, exploring its technical merits, its place in horological history, and its impact on the brand's development, addressing the various aspects mentioned, including the differences between the Valjoux 7750 and column wheel movements. We will also touch upon the use of the Valjoux 7750 in other brands, specifically Fortis, and consider aspects of pricing and availability.
The ETA Valjoux 7750: A Foundation of Chronograph Excellence
The ETA Valjoux 7750 is, without a doubt, a legend in the world of mechanical watchmaking. This automatic chronograph caliber, originally produced by Valjoux (a name derived from the Vallée de Joux, the heart of Swiss watchmaking), established itself as a benchmark for reliability and versatility. Its widespread adoption by numerous watch brands, from prestigious names to more accessible ones, is a testament to its enduring appeal. The Valjoux 7750's success stems from a combination of factors: its robust construction, its relatively affordable manufacturing cost (compared to more complex movements), and its adaptable design, making it suitable for incorporation into a wide range of watch styles. Its architecture, employing a coulisse-lever escapement, provides a reliable and efficient mechanism for controlling the chronograph function. This mechanism, while less refined than the column wheel system (detailed below), offers a balance of performance and cost-effectiveness. The 7750's modularity allows watchmakers to customize its functionality, adding or removing features to meet specific design requirements. This flexibility has contributed significantly to its longevity and ubiquity.
The Valjoux 7750 movement is characterized by its layout, which efficiently integrates the chronograph mechanism with the mainspring and automatic winding system. The movement's components are meticulously arranged, minimizing space while maintaining ease of assembly and servicing. The 7750 boasts a respectable power reserve, typically around 46 hours, sufficient for daily wear. Its relatively high frequency (28,800 vibrations per hour) ensures accurate timekeeping. These features make the Valjoux 7750 a solid foundation for a wide range of Valjoux 7750 watches, from sporty chronographs to more elegant dress watches.
