Anyone Tried Tg watch regulation software

normally when I think of Seiko crowns I think of a crown that looks different than what your assortment has. I think is Swiss crowns as having a gasket inside the crown that goes around the tube. Where crowns Seiko typically has it’s a little tiny gasket that goes on the crown and goes inside the tube. To that may be an issue perhaps then of course there’s the thread size issue.

as I was just on this website finding a jewel for somebody on this group let’s see what they have for Seiko crowns. No pictures of but we have a problem notice they’re not just the standard 10 there also 11 and 13 that will be a problem.

then let’s look at the parts list at this link and now we know what the problem is. Go down the list and see if the stem and there’s two of them one of them is a tap 9 which may be what you have. So yes it appears to be that Seiko stems like Swiss stems can come in different diameter sizes and they will not fit a crown designed for a size that you don’t have.
