UNLESS YOU'RE FORTUNATE enough to have a watch with a manufacture movement (one made in-house), yours will be an ébauche; an engine made by a specialist maker and bought-in by a watch firm. If it's a chronograph, chances are there'll be a Valjoux 7750 behind the caseback hence the old Swiss saying: 'Vous n'êtes jamais à plus de 1.83m d'un Valjoux 7750. It's probably the single most common mechanical chronograph movement.
It very nearly wasn't like this. When the 7750 started life as a young movement back in 1973, the watch industry had hit a peak of craftsmanship, tech and materials quality. It meant Seiko, Zenith and an alliance of Breitling, Buren and Heuer were all able to claim the release of the first automatic chronograph movement within a sneeze of each other: the cal.6139, El Primero and cal. 11/Chronomatic, respectively.
All of a sudden, venerable Valjoux was left wondering what had happened. The firm needed a new automatic chronograph movement to offer a cost-effective competitor.

Will China Change Everything? - China is tearing up modern motor manufacture but is yet to make more than a ripple in the classic car world. That could be about to change dramatically
China now dominates the automotive world in a way even Detroit in its heyday would have struggled to comprehend.Helped by Government incentives, the new car world is dominated by China's industries: whether full cars that undercut Western models by huge amounts, ownership of storied European brands such as Lotus and Volvo, or ownership and access to the vast majority of raw materials that go into EV cars, its influence is far-reaching and deep. However, this automotive enlightenment hasn't manifested itself in the classic world in any meaningful way - until now.
