Yes, in the meantime I found more 'versions' of this movement, eg in the imitated Montbrillant Dator (great scales, but no moonphase ) . I just wish they'd combine the moonphase window and scales of both watches, and remove the false insignia, what a great watch that would become!
Also I am sort of confused now about this Chinese 7751: so far I thought that the Swiss 7750 and 7751 derived from different families and could easily be distinguished that way (fork date for 7751, moonphase at 3 for 7750 etc).
Now I read that the recent Chinese copy of the 7751 is a rather primitive modification of their 7750 engine, with 'issues'. Only one model (the ugly Bauhaus) claims to have a true Asian 7751 - now how could that possibly be?
Since you have this Longines copy, did you notice any of the published problems with this modded 7750, mainly:
- 24hr subdial slow, ie falls out of sync (meaning they use friction, no gearset, to drive the hand, or simply loose axles??)
- badly aligned day fork (the main reason why I hate these forks and want windows like Zenith's 410)
$300 is not a low price, even today, esp for a copycat version. Even my Navihawk and Skyhawk cost considerably less and both are genuine and highly complex animals.
And a last issue I see: apparently these watches are hard to find, due to their legal implications. Here in Germany I could not locate a single online offer, and if ordering internationally the purchase will cause major issues at the customs counter, and extra taxes to boot.
I may still be out of luck, and have to wait for models without the faked insignia, by other Asian watch makers like Trias etc?
