That movement is around 800 parts to the JLC's under 600 and ~50% thicker than that of the EL2 and without the additional complications of a 24 hour indicator, gmt hand, push button function selector, radial power reserve, or any claims about durability. There are few other comparisons for this kind of complication but based on what little competition there is, JLC certainly seems to have done an amazing job building an elegant and well packaged movement. Busy but not messy.
