    What movement is in this Ailang?

    I found this watch in my AliX travels - Ailang AL8821-1. Does anyone know what movement it uses or have any information about this brand? Thanks.

    Looks like a decorated PTS S-05

    PTS Resources Limited

    Edit: It's actually the very similar JHLS 33

    Just to follow up on this. I've been reading some old threads on this forum about these dual balance movements but I'm still confused as to what the second one actually does. Is it 100% just a decoration that sucks power for no reason or could it theoretically have some beneficial impact on timekeeping (even if it has no real practical impact, e.g. tourbillon)?

    As I understand it, there are essentially two complete movements, each with their own mainspring. One powers the hour and minute hand, and the other powers the second hand. Theoretically, the resonance between the two balances could help keep them more consistent, but likely there is no measurable benefit or detriment. Others may have a better understanding than me.

    I think you're right based on what I've observed. I saw a retailer sales video for this watch where you can see the wheel on the right stop, freezing the second hand, while the other one keeps going (and presumably still advancing the minute and hour?). Quite an interesting thing, and I like the look of it even if it's not that useful.

    You can see it around 50 seconds in:
