The Tissot 763 watch movement, which was likely introduced around 1966, shares similarities with the ETA 2522 movement. However, it differs in several aspects, including the presence of Kif shock protection, a distinct rotor shape, and an anodized alumina barrel with life-time lubrication. It is worth noting that the specific dissimilarities between the Tissot 763 and the 624 movements are not known, suggesting that the designation might have been changed in 1966. The Tissot 763 movement features an automatic mechanism, a sweep second function, and a date display that can be adjusted by altering the time between 20:40 and 24 hours.
