Which movement in $35 Rolex

[GrimReaper]

I bought a Silix special Rolex blue Submariner.
The movement is Asian 21J, but it doesn't look anything like DG2813 which is in my 2 Omegas.

I would say it is somewhat better, second hand has more constant movement, it doesn't slow and accelerate as much.

Yep shitty bottom end 21j...good news
If it dies you can replace it with a top tier Chinese DG2813 for $27...It a long way from junk amigo.

That's a Seagull ST6. Has 21.600 beats, so it's slower than Rolex gen, but reliable and can be regulated quite ok. If needed - I have spares
