:thumbsu:I need some help here, I'm going nuts trying to find the answer.  I have an old Seiko Chronograph Sports 100; 7T32B watch that my son gave to me to replace the crystal.  Seemed easy enough, my first thought was to pry the Bezel off, rather than taking off the back plate off and pulling out the stems to drop out the movement.  I don't like messing with the tiny levers that hold the stems in place.  Anyhow, I proceeded to pry off the bezel which required a bit of an effort.  When it came off, out came to a fine stainless steel ring and a small plastic green ring with some very fine numbers printed around the inside of it.  After replacing the crystal, I haven't been able to figure out how to install the bezel.  My insight tells me that there must have been some sort of an "O" ring type seal/retainer that holds the bezel in place after being pressed in.  However, there was no sign of anything resembling an O ring that fell out of the assembly once it came apart. Although there seems to be grooves there on the case and the bezel where they go together to facilitate a bond between the bezel and the case.  I've been looking for days on the internet for some sort of a diagram, or instructions about how to reassemble these parts, but up to now I found nothing.  Can anybody out there help me with this issue.  Thanks much and God bless.

The Bezels snap back on. Some tight ones need the help of a crystal press. If you removed the bezel with to much force from just one side it could have been distorted, if so it will never re-fit.

Thanks for your reply, I'm very sure the bezel is not distorted, or warped because I didn't have to pry it hard enough to do that.  The crystal set into it perfectly all the way around and when together, the case and the bezel fit perfectly flat with no rocking motion, as though the bezel were perfectly flat.  The bezel goes together with the  case very loosely with about one MM of lateral play all the way around like there needs to be some sort of a ring within it to snug it up and hold it in place and seal it.  What puzzles me is that There is no click ring within the bezel and the case and when it came apart, the only thing I found was a stainless steel ring having four evenly spaced pressed tabs that raise up at a 45 degree angle.  The inside diameter of this ring is too small a diameter to fit over the outside surface of the ring of the bezel that goes into the cavity of the surface of the bezel that goes into the cavity of the case.  The outside diameter of the stainless steel ring does fit perfectly within the inside diameter of the cavity of the case.  In lough of a click mechanism, the pressed tabs of the ring could act as a sort of friction clutch when set, bringing up another question, as to whether the tabs go up, or down withing the cavity.  I'm looking for someone who has had experience with the bezel/case relationship of this particular watch, a "Seiko chronograph sports 100, 7T32B"  to verify my observations and to tell me what kind of device holds the bezel into the cavity of the case.  Anybody out there please step forward.  I really don't want to improvise, but I have some ideas that might work out very well.  Thanks and God bless.

    • Hello and welcome to the fo4um. Enjoy
    • Welcome to the forum, enjoy.
    • You're asking a pretty broad question and you didn't specify the machine but yes it's simple especially if you have the right machine. The question has problems but I'll take it as it is. Is it really that simple yes especially if you have the right machine. So in the video below he's making a screw and yes it really is that simple but pay attention to the machine it is not simple at all probably wasn't cheap but it is small it will probably fit in your garage. Unfortunately wouldn't fit in my garage as it's far too cluttered up with things. In the video he talks about making a screw and pay attention to the machine. The machine has lots and lots and lots of cutters and lots of things to do lots of machining all-in-one machine conceivably one step after another all programmable. If you look at his channel lots of CNC's stuff and there are several other videos related to this machine. He goes to the factory where they talk about it and show all the other machines they make in Switzerland.  I did look up the specifications the machine I don't recall the price it's not going to cut wheels I think it has a maximum diameter around 11 mm basically it's really good for making small diameter watch parts. Then in one of the other videos he goes to a factory that used to make parts with waterpowered machinery been in business for 100 years and everything they now make is made with CNC machines including this one. What was interesting with the factory photo was that when they make some parts they can put them on a optical comparator comparator compares with whatever the reference is and the machine can be programmed to adjust its cutting to make sure everything is actually being made to specifications. Oh and then somewhere in all of this there was at least one picture of a balance staff can't have a CNC Swiss machine without making balance staffs.   It would be really nice if we had pictures of the machine. Then yes if you look at the page for wheel cutting you can enter parameters and it will generate a G code but he left out things? Notice he has a picture of a complete wheel but the G code isn't making a complete wheel it's only cutting the gear teeth I don't see whereas the program for crossing out the spokes? Typically when you see people cutting gears once the teeth are cut most the time the spokes are cut by hand. Occasionally someone will mill them out but typically not with the program which seems strange if you have CNC capability for instance one of my friends fill it used to design assembly line equipment or things to make things. So his hobby was to continue to make tools to make things like clocks. Very interesting and clever clocks but his true fund was making the machines to make the clocks. Then machine is not controlled by G code like we would typically find today as the stepping motor controller he has was made a long time ago and the individual controllers used a textbased program. So the company had a editor you could write a program to cause each the stepping motors to do something. So basically once you figure out how to cut a gear he would just change the parameters for different size gears so here's an example of a gear as you can see we have the teeth and the spokes. Then we have a picture the machine which sucks because it would've been so much nicer if I could've taken a picture when it was cutting a gears so we can see things better. Then yes there is a worm gear stepping motor indexing this is a mini lathe and the indexing is at the end of the lathe head hiding. The basic operation of this machine would be brass sheet not cut to a specific diameter size not even round mounted on the machine. Then it turns and a milling cutter will cut the diameter. Then the gear would be cut with a gear cutter. The same mill cutter for the diameter although conceivably change the size I don't know but basically the same milling for cutting the outer diameter would be used to cut the spokes. I really can't remember how he did the center hole but whatever it was was very precise.          
    • Yeah I know the site and the creator of it.  the two video clips are good examples of the quicker method and a full tear down.  the quick method will work in many cases. But not always and not for all the different movements.  I strongly suggest to not bend the four tabs as was done in the first clip.  Instead there are three tabs that insert into the top plate, Much saver way as to not break a tab.
    • I found a motor that is 3/4 hp and another that is 1.2hp. They come with speed controller. So I don’t think I would need a wiring diagram. But I sure appreciate you offering your help! Do you think 1.2 hp would be too much for a watchmaker’s lathe?
