The shape of the case of SBDC051 is cool! I've been feeling lately、I was able to get a used SBDC051 in good condition, so I re-MODed the clock I made last time, including the dial and hands.。 I have two problems、Chapter ring of SBDC051 (SPB051) seems not to be sold outside the company、never seen。Search does not come up。Different sizes for boys and others。The SBDX019 dial has a minute scale on the outer circumference, so I personally want to combine it with the silver chapter ring.。Then measure the size、The outer circumference of the boy's chapter ring, which was made by cutting the inner circumference last time, is about 30 mm.。different height。When I put it in the SBDC051 case, it moved in the gap, so I was wondering what to do.、Spread the sapphire glass packing height 2.5mm for another watch that you had at hand slowly and carefully with needle nose pliers, align the outer circumferences, and attach it to the outer circumference of the chapter ring.。because there is still a gap、Do the same thing again and install gaskets around the outer circumference.。This time it's too thick to fit in, so slowly and carefully scrape the outer edge little by little with sandpaper.、Scrape top and bottom、It is still a little high at 2.2mm in height, but it fits perfectly around the circumference, so I installed it.。The height is press-fitted with the expectation that some space will escape due to the curvature of the glass.。0.2The glass may be loose about mm。I was so busy working that I forgot to take a picture.。 The next problem is that the diameter of the dial is different。SBDC051 is a general 28.5mm dial、The dial of SBDX019 is big...。I had no choice but to do it so far, so I shaved the outer circumference with a router.。Rely on your senses, appearance, and the scale on the outer circumference、so that the center does not shift evenly、Clear the outer circumference problem by scraping so as not to break the circle。However, although the dial was cured,、I entered through a gap and was covered in iron powder。。I want to avoid scratches and dirt.、It will not fly with dust blowing、Even rodico can't get it...。Take the plunge and wash with water to feel good、Remove fine particles with a rodico、After cleaning the dirt on the index with a glass pen、Complete revival! No noticeable scratches or dirt、I managed to get through。 It took a lot of time and effort to scrape the chapter ring and the dial、I was able to do something with 120 points on my own.。The luminescence and color of the bezel match、I like the reflection of the night light。This component SBDC051 + SBDX019 dial, hands, buckle + SEIKO logo crown (probably ebay)+ Non-genuine chapter ring gasket = SBDCX0519?
