Great quality and care!

I've purchased this and can't be more satisfied with the quality. Not many, if any, produces parts for modding the 0030 series, and this simple ring opens a lot of possibilities! Besides adding a couple of finger gloves for doing the job properly was a nice touch. With all probability will buy from here again

Thanks Alvaro! It's been a pleasure. I hope you have many great SKX013 modding adventure coming ahead. =)

Very nicely cut, polishing can be improved

I needed a polished chapter ring for a complete build I'm doing on an SKX013. It's really well cut, nice sharp edges, but the polishing can be improved. I noticed just a few rough spots here and there and there are also some faint horizontal lines running around the surface. Not sure if this is from the machining process or an indication that the ring was polished in only one direction. It was no big deal though as I just ended up polishing it a bit more with my Dremel.

Yep. You are actually right, it's machine polished in one direction. For our dials to fit SKX013, we had to reduce the width size of the CR by about half compared to SEIKO's stock plastic CR and still keep the CR angled like the original. To give you a perspective how tight the clearance, the CR is 1.0 mm width and 0.25 mm from touching our dial indices when installed. Any smaller, the CR will be too fragile to produce even though its 316L stainless stain. From an engineering point of view, these chapter rings were by no means easy to manufacture. It was a manufacturing feat! So the faint flaws do occur on occasion. Unfortunately, this is part and parcel of machining process. Of course to reach perfect finish, like what you did, each CR has to be hand polished. Prices of parts always astronomically increase with finishing. I did not opt for hand polished as with this option, each CR would probably cost est. $60 USD due to the intensive labour cost involve. I honestly think no ones going to buy a CR for a $60 USD. As always, thanks Theo for sharing your constructive feedback!
