The replacement would be another Valjoux 7750 variant, with the column wheel like Longines but also a Co-Axial escapement. The new Omega calibre 3330 is truly a modern movement, complete with a silicon balance spring, but it's a Valjoux 7750 at heart. It's disappointing that Omega chose the 33xx name for it, though, given how …

it's also because the 7750, like the ETA289x, starts off at Elabore grade, not basic or standard grade. That means it's adjusted to 3 positions. The two most consistently accurate movements I've had--big surprise--are the 7750 and the 289x. Is it because they're such wonderful movements?

But the Valjoux 7750 seemed to become a supernova, burning brightly for a very short time and then imploding. By 1975, after only two short years, Valjoux customers felt the squeeze of the Japanese quartz movements to such an extent that orders plummeted and Valjoux decided to halt production of it completely.

A very common issue with the ETA/Valjoux 7750 indeed. It is NOT a difficult fix, but it involves a few parts being replaced and you'd have to decase the movement and have the hands and dial removed. Gaining access to the day-date module from behind the watch is A LOT of unnecessary work.

The cal 7750 was developed by Valjoux long before this merge-up. As Valjoux is now a part of ETA, what used to be the Valjoux 7750 is now the ETA 7750, with the same specs. Technically, only if it's a 7750 assembled before this merge up is a true Valjoux 7750. Else, simply call it the ETA/Valjoux caliber 7750. That makes the cal …
