I haven't seen any rep seconds hand that tapers like the gen so I opted for gen hands. Money well spent IMO, especially when using a 3135 clone movement.
I was so undecided on whether I was going to build a 16610 or a 16613 I ended up buying gen dial, hands and datewheel for both models. I decided on sticking with a 16610 build since I couldn't afford the gold bezel or crown after. lol
Edit: I just checked OFrei and they sell aftermarket 3135 hands and the second hand looks like it tapers. Could be an illusion though. Not bad at $26
