At present, the 4130 clone movement is very stable, with minimal difference from the original factory. The hairspring has also been optimized, and the watch uses 904L steel. The ceramic bezel is produced in the Clean Factory and will never fade. Durability is greatly improved.
If you want to be cheaper, you can choose the A7750 movement, which has the same performance but the price is half the former, and there is no difference in appearance and material.
