anyways just sharing some info of my mods i done to this ZF BB58 as I've seen many are sharing their ideas and wonderful works here regarding BB58. So I would like to share some of mine too to contribute ~
1. Purchased original case tube - screw crown from ZF works flawlessly when screw into Gen Case tube, but GEN case tube threads are wider than the case hole itself. Needs to widen the case hole to fit the Gen Case tube. So with a little bit of modding done - it went perfectly fine.
(Crown no longer protrudes too long - crown tube img)
2. Dial - ZF dial is too smooth and plain , unlike Gen BB58 with textured dial. So I just covered the indicies as much as i can then sprayed matte spray paint over the dial in super thin misty layers resulting in textured dial
(I tested it over some other spare seiko dials before working on the actual thing =P )
3. Swapped the internal movement from 2824 to 2892. The Lever spring is easier to mod with a file so ghost date is removed + smoother hand winding experience. Also, 2892's returning to position 1 is more responsive and less likely to jam up the keylessworks (Maybe I'm bad at modding 2824?)
4. I own a Gen Pelagos 39, fell inlove with the T fit clasp, so purchased a rep Rolex braclet with microadjust , hack + saw + drilled and mod the single end half links to fit BB58's endlinks and tada! now it works perfectly lol ..

So ... overall I think ZF base is not too bad, with a little elbow grease the rep can look closer to Gen haha ..
Feel free to PM me if you wanna do similar mods , I can share some experience lol .. Sorry for the long thread , just am super thankful that I'm able to join in this wonderful group ~
