I did this because I am at the bottom of my stock, and the SKX007’s that I received in the past were mixed: Most were OK, but many were with mis-aligned chapter ring. When I had enough stock, it was simple: put the bad ones aside and wait for sapphire-orders and fix the dial ring-issue while installing sapphire. But now, all stock that is left, are the ones that I initially put aside for the orders with sapphire. So from now, every SKX007 needs to be taken apart to fix the dial ring issue, so I am selling them with sapphire.

I ship them with aligned dial rings, and I receive about 50% with aligned dial rings so sometimes I have to wait a few shipments before I can fulfil an order (the mis-aligned ones are put aside and the dial ring is fixed when I install sapphire).
Sapphire-options:

• seamless double domed with blue and clear AR coating
• flat with large beveled edge like original glass, with blue, clear, green or red AR coating.
• flat and double domed STEPPED sapphire, made especially to be combined with the sloped bezel inserts, also with blue and clear AR coating.

• 100% Japans: parts and assembly, so a “real” Seiko.
• Hard to see: sharper grip on the bezel and sharper transition between polished and brushed surface, it seems that the workers that make the made in Japan version put just a little bit more effort in their job.
• Easy to see: “made in Japan” and “21 jewels” on the dial, “Japan” on the case back. But also inside on the movement.
• Alignment of the dial ring: this is a well known issue with the SKX007. The dial ring is a loose part, it lies on an edge in the case, and there is a “nipple” that keeps it in place. But the nipple is smaller than the hole it goes into, so the dial ring can move a bit. This issue appears equally in the K and the J version.
  I try not to sell those! I keep them aside and correct the aligment when I install sapphire.
• The bezel is a part with a function (how long you are submerged). Being exactly at 12 is not its function, and Seiko does not care. The way the watch is made, a complete bezel is pressed on the case) almost prohibits the markings to be at 12: there are too many variables: click ring, indentations on the bottom of the bezel, how the bezel insert is placed in the bezel). If you want a perfectly aligned bezel, the insert must be placed after assembly of the watch, and that will result in a much more expensive watch. I can do that, if you ask for it, but will charge 25 euro for it. I have to remove the bezel, take out the insert, press back the bezel and re-install the insert.
