The Seiko 4R35 is the in-house version of the SII/TMI NH35. They are essentially the same movement. As for what materials are used in the components of the 4R35 vs. the NH35 I simply don’t know. As an owner of both movements (Seiko bloody monster and various other manufacturers for the NH35) I don’t find the Seiko 4R35 any more smooth or accurate than the NH35. Both movements are defintely not as smooth as the Miyota 9000 series movements for sure.
I don’t find the thickness to be an issue, but of course that is my personal opinion on it. It is not a one piece block like say a Boschett Cave Dweller where it feels and appears really tall on the wrist. It wears more like a 14mm thick watch in my opinion.

Is the thickness an issue? was thinking of picking up one but 16mm seems huge. what are your thoughts?
