This might be some serious idiocracy, but anyone who has changed a crystal on a Seiko with a metal crystal retainer will know the difference in weight to the other metal components. Returning the retainer is often snug but still begs the question of water rating capabilities.  I am Struggling to find a crystal retainer for the Arnie and have pondered the question. Could it be 3D plastic printed with water resistant capabilities? I am prepared for a barrage of abuse for such heresy. Cam |

Don't know the capabilities of 3d printed plastic for that application, wouldn't it be simpler to get one turned out of metal? You have the broken one to provide the dimensions.

The retainer ring doesn't really have much to do with WR. It is just there to keep the crystal from popping out if any internal pressure manages to build up. The plastic or whatever material the crystal gasket is made of does the actual WR.
My guess is that a retaining ring made of the right type of plastic would work fine but it would have to be made from a solid piece rater than 3D printed.

Have you tried checking the dimensions against SEIKO CRYSTAL RETAINING RING FOR 6309-7040, 6309-7290, 6306, 6105 DIVER
Which are available on eBay, perhaps they can be machined to fit instead of starting from scratch.

That was my first thought. Unfortunately it's not even close. The 558 is about 15mm less in diameter. |

No current 3D printing tech will give you the accuracy you need for this part and a plastic part will just warp and pop off. Send it here and I'll get it laser welded.
