As part of my watchmaking journey I decided to replace some bezels on a watch that bezels are very hard to come by. I was able to pick up a donor watch with a bezel that I am taking measurements from. I am slowly learning fusion 360 and printing my prototypes. Once I have a working prototype I will manufacture them from either titanium or aluminum. This is where I am now on these orient dive watches.

Update: I have manufactured a trial bezel from ceramic. It has a nice friction fit but loses the fit when a spacer ring is used between the watch body and bezel. This needs to be adjusted. I still need to add the coin edge and other markings but I am getting closer and closer. Here are a few pics of this process. The first picture shows the ceramic bezel in it's green state before removing from the workpiece and an 8+hour sintering cycle. Notice how much this ceramic shrinks from green state to final state. Original bezel can be seen sitting inside the green state ceramic one.

that looks great. I am new to the "watch scene" but would like to design and make some watch components myself. I work in the machine building industry and have access to several CNC machines. Share your project. Maybe I can be helpful to you.

finding an online cnc lathe company that wants to do these id difficult. No one wants to just make a few units. I have a few more options that I am looking into

Maybe there's a facility like Munich's Makerspace in your area, where you can rent time on a machine?

      Not a family member, and yes, it no way near as good, as some information got lost from original site and some information got incorrectly copied. The original site is available as iOS app here: https://apps.apple.com/fi/app/ranfft-watch-movements-archive/id6502008939

      Seitz Tool - Help determine if Seitz or not

      By Hawaiikook808 · Posted

      Outstanding, Marc! Your information is really helpful and clears this up, especially given that yours were purchased as sets. Thanks, man. So, it appears I jumped the gun on this one, but I am relieved. I will say, though, that all of my reamers and concave pushers are number-stamped and appear to be of better quality.  Also, the bayonets on my pushers are actually the same color as the steel.  The next thing to do is restore the heads of these pushers with some polishing paper.  Alex at the Watch Repair channel has a nice little video on this.   I appreciate your help!

      Just installed it on my iPhone (my only iOS device) and it appears to be intact and functional. I may have to go out and buy myself an ipad just for this app.

      Seitz Tool - Help determine if Seitz or not

      By Marc · Posted

      I have two Seitz sets, one ancient (with the 3mm anvils) and one just old (with 4mm anvils) plus a collection of spare pushers of assorted vintage. Not one of them is marked with it's size. Something which I have found very irritating when I have been using the tool and not returning pushers to their correct place in the tray every time as it means that I have to get the calipers out and measure them. These were bought as sets and collectively I have over 100 pushers so it would seem highly unlikely (if not inconceivable) that they are all cheap knock offs, especially as they are old enough to pre-date the prevalence of the Chinese knock off industry (at least as applied to watch making tools). I therefore believe them to be original Seitz parts. And there is no numbering. The shape of the bottom of the pump pushers is the same as your photo. The only thing that may not be the same is that the slotted insert (looks like a screw but is in fact a bayonet) should be brass. Yours looks the same colour as the steel but that could just be the lighting.
