If you want it done right, sometimes you have to do it yourself.
My Seiko Prospex SBDC111 on a Haveston M-1936-B A2 Service Series Strap. I really find the strap's "Field Khaki/Sand" tones work very well with the green tones of the watch. A very vintage military field/dive watch look and feel. Very appropriate given the military history these modern re-issues are decended from.
And, my SBDC111 is finally working as it should and well within my personal tolerances. If you follow my YouTube channel, I've been having trouble with the movement since I got it. Long story short, the 6R35 movement in it is no good. Probably needs an overhaul and service to get it up to spec. But, I've personally found the 6R35 to not be that great a movement. I actually prefer the older 4R35 (NH35A) as they've been much more reliable and consistent performing in my experience.
As such, I did a movement swap recently from the 6R35 to an NH35A. It was a successful operation and my SBDC111 is now performing excellently.. Basically +/-0 s/d over the last 2 days since I did it.
I also reset the hour hand alignment while I was at it as it was about 5 minutes behind where it should have been.
I couldn't seem to reply or add a comment to the Welcome post. So, I'll just do it here. Name is Wing. Just a simple watch enthusiast just like the rest of you here, I imagine. Figure I'd drop first w...
Wow, thanks for sharing this story. I wonder whether NH movement is able to replace 6R perfectly without any modification? I truly admire your bravery of making this decision. 🙇🙇
That surprising me the most where 4R perform better than 6R movement, which is totally different price point.
I wish Seiko could put a little more work and effort to make 6R worth the money.

I've done a lot of watch mods in my past so taking the watch apart and tinkering with them isn't that hard for me. Though, I don't do it as much these days as a few years ago.
Yes. Essentially all the 4R and 6R components are essentially the same. The 6Rs just have higher power reserve and some additional upgrades components which I think is supposed to make it maybe a little more shock and antimagnetic.. maybe. Otherwise, the dimensions and hand set are all the same or compatible across them all. I did a 4 part video just documenting myself doing the movement swap and what was involved.
I reused the dial and handset from the 6R to the NH35A. I also had to swap the plastic movement spacer that is around the 6R35 to the NH35A. It is a little thicker than the one that came with the NH35.. Removing and installing this plastic ring required a slight disassembly of the movement to get the date disk out of the way to be able to get the plastic ring off and on.
It is a pretty well known fact the 6R35's are erratic much of the time from the factory. If you ever watch Spencer Klein's YouTube channel, he's a bit of a vintage Seiko expert and familiar with the infamous over lubrication that often messes up the 6R35 movements.
The 6R35 is essentially a solid movement. They just are not treated and made with enough care from Seiko during production, unfortunately. So, that requires an overhaul and servicing to get the proper lubrication and then it should run pretty well when you get one that runs like shit out of the box.

Wow, thanks for the full info man. I truly appreciated your insight over this.
Lucky for me, Seiko has extended their warranty to 3 years in my country. I might take them to service before the end of warranty then 😬😬
