What at first glance appears to be an ordinary Longines calibre L729.2 actually conceals a remarkable milestone in the history of Swiss quartz watchmaking 😅. Hidden inside the black plastic tube is one of the first three tuning-fork-shaped quartz resonators ever manufactured in Switzerland. Also the CMOS IC is one of the first built in Switzerland on industrial scale with Hughes Microsystems’ license. Three watches were built using these pioneering Swiss-made quartz resonators and CMOS IC’s. This is the sole surviving example, originally presented to André Beyner. Starting with these three watches, the Swiss definitively introduced ‘home-made’ industrially produced and reliable CMOS IC’s and switched from bar shaped quartzes to tuning fork shaped ones aligning with the industry standard imposed by Seiko already in 1967. ESA/ETA 940.111 / Longines, L792.2 prototype with one of the first three Statek licensed quartz resonator and one of the first Hughes Microsystems licensed CMOS IC made in Switzerland, 1976 For a full description and more pictures follow the link in bio. by @massac_jp
