Looking through my odds & ends today I came across this movement ring but can't think what it came from.
It will be Seiko as I have broken one or two for the bits but not other models.
It would be nice if it turned out to be the 7C43-7000 I need but things don't usually work out like that. :undecided:
It is 2.25 mm tall and the outer circumference is stepped with the step at the dial side being .5mm. It is 29.1mm across as is a 6309 one.
It has 3 square "pips" around the upper side. The movement side is completely flat bar the stem notch. There are also 3 separate cut outs around the side wall which you can just make out in the photos, these might be a clue to someone. TIA

It's a a movement ring for the circa '70's 6117-8000 navigator , 6105-8000's, 6217 diver. That era of watches.

The 7c43 ring is the anti-mag shield with the tension ring built into it.

Odd that as I've never had any of those except my 6117 world time and that's all complete, it's a 6400 and it's ring is not the same.
I wonder where I picked this one up:confused:

Are you saying the 7c43 diver doesn't have a separate holding ring as per normal? as I'd never know.

No, it's more of a cup that the rim fits down on the edge of the movement with a wavy spring on the edge. The cup presses down on the edge of the movement when you screw the case back down on the spring .
