ZF have best crystal and strong genlike cyclops effect, cf parts on all i think. Smooth bracelet (arf like) hard snap on clasp like gen. Almost flush recess, good dw and aligned
VSF have best «gen» 3135 movement touch, clasp click sound and spring, best genlike recess on all sides and good aligned rehaut. Good dial and insert.
RXF have smooth a2824 movement and good dw, crystal, insert and dial. Ok recess
something like this, all amazing watches! I prefer ZF reason is the crystal/cyclops look gen.
VSF Rehaut has a spacing issue unless it's been corrected like some of the LV I've seen ?
