Hello, community! I'm a new member to the site and want to tell you a little about myself, why I'm here and I'd like to ask a question which nags at my curiosity and hopefully some of you may be able to answer. When I was 18, I joined the US Navy and as a going away present my grandmother bought me a beautiful Gruen watch which was promptly stolen. The never quite completely got over the loss of that gift from my grandmother and about 8 months ago I spotted an identical vintage Gruen on Ebay that wasn't running. Of course, I bought it with just the thought of having it in a drawer as a keepsake. Well, I've always been good with tools (Navy Machinist) so I bought a set of Moody Jeweler's Screwdrivers from Amazon and a can of lighter fluid, and not knowing the first thing about watch repair(what the hey, it wasn't running anyway)took the watch apart cleaned the parts and put it all back together, wound it and low and behold it started ticking. Well, this was a stroke of good luck, but it lost time like it was the watch from 'Back to the Future". After paying a hefty bill from a watch repairman who re-cleaned, timed and adjusted it, I got to thinking maybe I could do what he did and it might just be a rewarding and pleasant hobby for me. Thus, from all this grew a passion for vintage Gruens and a desire to repair them. For the past 7 months or so I've been learning a few things about watch repair, studying books, gathering a few quality tools from Ebay and playing around with some Gruens I picked up cheap on Ebay. I lately had the idea that a few of the more common parts, such as balance staffs, might be a good idea to have on hand rather than waiting on an individual part through the mail. At 76 years old, I can still learn new tricks, but turn-around-time works against you when you're my age.

Now my question! I see "lots" of Gruen parts being sold on Ebay, mostly in little glass vials with numbers or letters an them, but some just loose parts, from all sorts of different brands parts suppliers, but nothing else to identify them as to which Gruen movements they where originally intended for. Not only am I clueless as to which movements these "mystery parts" fit, but the sellers are equally uncertain as to what they are selling. A query to them usually results in "from an estate sale" or "sold as found". Actually, many of the watchmaker tool sellers are vague about using the tool they list for sale, but at least I have an inkling of how they're used from being a tool head most of my life. How in the world do you identify these orphan parts! I've done hours of internet searching and I still don't know. I'm beginning to wonder if anyone in the world knows!???? It's making me daffy! ? 

I would sincerely appreciate any help the community could give me on this and, let me also say, it feels good to be here.

Hi Gruenguy,  here's some Gruen info for you from Mike Barnett, or Mike The Watch Guy :-)

http://www.gruenwristwatches.com/gruen-caliber-index-for-repairers-reference.php

His site is a great resource fro Gruen collectors.

And yeah, trying to put together a parts inventory from old undocumented material systems can be, uh, interesting to say the least.  But, as you learn the parts, sometimes you can spot what you need from pictures, other times you'll need to hunt, but you can always ask for help here!  You might even get it, too :-)

Have Fun!

    • 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?
