I'm new on this fantastic forum and spend days and days reading.
Thanks also to ALE for his great info!
I've got a Noob 177N and are very happy with it.
Runs within 3 seconds in 24h, after adjusting it a little bit.
Very good Lume and clear sapphire.
Micrometric screw is too short, but hardly visable.
No Y shape incabloc but I think no rep 6497-2 has it.
Titanium will scratch more easily than stainless steel 111, but mine is very clean even after every day use for months.
Changed straps a lot and still OK.
Runs >48h after winding.
Took it apart for getting to know it
.
Love the titanium low weight for my small wrist.
Have no information about the H-factory but hope it helps you choose.
