Which movement

[bally]

Hi All
I'm looking for a replacement crown and stem but not sure which movement I've got, It just says 4C. Thanks

Not sure but it looks like very similar to this one.

Which movement is this - Omega Aqua Terra 150M - from Turkey Holidays

Any idea ? It was running +20sec. Adjusting was pure pain. Beat error always changes with adjusting speed. Best i could do is beaterror +0.9 msec and rate -2sec a day.
