I came across this forum a couple weeks ago and read through all kinds of threads on how to reshape cases, assemble watches etc.
Since I love tinkering with all things mechanical and always loved watches- I bought some tools and a raffles 1675 set to get started.
Because I found the knowledge on this site very helpful I wanted to give something back and maybe help others who are at the beginning of this hobby too - I wanted to share my experiences with this build.
So I started with the bezel - there was some kind of protective plastic on top that I had to polish away (you can still see some traces at the 8) because I was afraid that it would give uneven fading once the insert hit the bleach.

I mixed common German bleach with water in a 50/50 ratio- because I found that pure bleach would fade the insert too quickly (I tried this with a JKF 1665 first - which came out too faded).

The other thing I found out with the 1665 was that you should not touch the insert once it’s in the bleach and the first minutes after. With the 1665 I went over it with a brush and it left streaks - I guess it’s a look, but if you want to achieve an even fade: just touch the insert at the sides and check it periodically by placing it in a bowl of water, because it will keep fading some more.
Here’s the 1665 for comparison:

Then I put the insert in a box with nails and gave it a good shake to give it some smaller dings.

For the crownguards I removed the tube and prepared two photos of gen cgs that I liked. I found that if you look at too many pictures you tend to loose the eye for the form.

Since I’m a dentist by day I have some nice diamond drills - but I found this one to work best. It’s a fine diamond drill with a very handy form for case reshaping. With this I gave the cg a vage form.
To open up the cg from the inside I used a sanding wheel - but be extra careful not to hit the case - it will leave nasty nasty scars that are hard to polish away
Leave some material for corrections (symmetrical form of upper and lower cg, polishing errors etc). Here you can see the „dirty first reshape“.

To polish the case I bought sand paper drums starting at 120 grid going up all the way to 2000 grid. If you are careful with your work here and don’t rush it you will have a case that only needs a quick polish with a cotton drum and some metal polish.
By the way - for the dremel work I bought a proxxon 60 series. It has enough power but is small enough for this kind of filigrane work.

Then I cleaned off all residue and assembled the dial, hands, crown etc. And you’re ready to go:

The only thing that bugs me with the build is the bezel assembly - it’s way to loose ( meaning that the whole assembly is easily removed) - I guess that the little plastic washer that comes with it is too small or something. Did someone find a good solution for this - or did you just glue the bezel retaining ring in place?
