The world of replica watches is a vast and often murky landscape. While some strive for meticulous accuracy, replicating even the most minute details of a genuine timepiece, others fall far short of the mark. This article delves into the realm of Valjoux 7750 Breitling clones, specifically focusing on the experiences and observations surrounding their quality, particularly in comparison to authentic ETA 7750 movements and the variations found within the market itself. The discussion will touch upon the frequently encountered issues, the geographic origins of these clones (particularly focusing on the "Shanghai 7750 clone"), and the overall reliability and longevity of these often-affordable alternatives.
The ETA 7750, a highly regarded automatic chronograph movement, serves as the foundation for many high-end watches, including various Breitling models. Its robust design and relatively high accuracy have made it a popular choice among watchmakers for decades. However, the cost of the genuine ETA 7750 is significant, leading to a high demand for more affordable alternatives, primarily in the form of clones, often produced in China. This demand fuels a market that ranges from surprisingly decent imitations to frankly poor-quality pieces, posing a significant challenge for consumers trying to navigate this complex world.
My personal experience several years ago involved a direct comparison of several Valjoux 7750 Breitling clones alongside a watch featuring a genuine ETA 7750 movement. The differences were immediately apparent. While the visual appearance of some clones could be remarkably close to the original, mimicking the dial, hands, and case design effectively, the internal mechanics told a different story. The most striking issue I encountered was the consistent lack of lubrication in the Chinese-made clones I examined. These watches arrived essentially "unoiled," meaning the numerous moving parts within the movement were operating with minimal or no lubrication. This critical omission resulted in significantly increased friction, leading to several immediate problems.
Firstly, the lack of lubrication resulted in noticeably increased noise. The genuine ETA 7750 operates with a smooth, quiet hum; the clones, on the other hand, produced a harsh, grating sound, clearly indicating the friction between unlubricated components. This excessive friction also contributed to a significant reduction in power reserve. While the genuine ETA 7750 typically boasts a respectable power reserve, the unoiled clones struggled to maintain even a fraction of that duration, often stopping after a few hours of wear. Furthermore, the lack of lubrication accelerated wear and tear on the delicate components of the movement. This resulted in premature failure and significantly reduced the lifespan of these clones.
