It is worse. The 3135 and 3135 clone fit loosely in the case. You have use really long movement tabs and bend them in a weird shape to secure the movement in the case. The JF is much better in this regard plus it is engraved between the lugs.
I have this same version in transit to me. After owning 3 of these JF's and going crazy on one build upgrading damn near everything from the dial, crystal and insert, crown etc.., I have found that for me, the only upgrades this needs is a gen datewheel and a gen insert. Everything else is good enough for me.
