NH35/4R35 Watch Build

[SeanWatch]

Hello All,

I'm extremely new to watch building or anything beyond just wearing them. I want to build my own watch, but I would like to have a bigger dial/face (around 38-40mm). Is that possible with a movement like Seiko NH35/4R35 which has a diameter of around 28mm??

 

Thank you,

Sean

Yes, it's possible but complicates things you will have to build more special parts like mov.t holder ring, or source a special case etc.

If one takes pride in how the watch is built beside how it looks that can take time money and effort.

If it wasn't for your dial size requirement, the esslinger kit is a close match as it comes with a NH35: https://www.esslinger.com/make-my-own-watch-kit/

As the NH35 has a date wheel, one thing to be aware is that the date window will have to be at the same distance from the center regardless of what size dial you use. So a larger dial will have the date window further from the edge.

Dr ranfft list the movement's dimensions the case would need to accomodate. 

Provided date window.  Filing to enlarge date window is a choice if you can find a rim  new/ used  for the window.
