Hi Everyone!

I'm a mechanics enthusiast (studying engineering, actually), and watches always caught my attention. I came across an Omega 30T2 from my grandfather and managed to replace the balance staff with a second hand stacking set I could lay my hands on. In the process I looked up a few things on the internet and came across the forum, thank you all, it's ticking now!

 

Cheers

Welcome to this friendly forum. Re-placing a balance staff is not easy. Normally you would be well into your apprenticeship before you under take that task, certainly not with an Omega.  

Well, in this case the OP succeeded as a total beginner in getting, at least, the watch running. Although we can't know how good without a timegrapher picture.

welcome to a very good watch forum.!  brovo!  on the shaft job and thanks to the net;  you found the modern version od "tech. manuals".  an engeering degree would be good also.  i do not use a "timegrapher [ I junked one,  it had 12 tubes (valves)].   i use a stethosope.    vin

SHello guys! Some updates from a full Omega saturday afternoon. I started checking the regulator pins as I asked in the other post. In the second attempt I got them where I think is better, the coil bounces but with little clearence. Then I started timing it. No timegrapher so I had to improvise: I tried an stethoscope Vin, but the one I had (asked my mother actually) didn't pick it up.

So I got the open source TG 0.5.0 running on my computer. My cheap mic wouldn't get it either, so I came with a "tech" solution: recording a voice message on my phone, with the mic close enough, and getting the audio file to the computer, then streaming it to the in-line as it were the mic. It started measuring. Quite a job, since I had to suspend the computer to record every time (over a minute each), to avoid any kind of noise, but at least I was getting some numbers. First ones: Not good. I was +200 sec/day. Moving the regulator from end to end got it from +150 to over +300. So I started checking again. Using more geeky stuff, slow mo vid, I saw the balance wheel getting barely 180 degrees from side to side. When I loosened the arm it clearly gained angle.

So I took it off again to find some markings on the plate where the arm sits, which were pointing it down (marks on the outside-side of the screw). Carefully removed them, cleaned the debris, and added just a micro drop of synthetic oil on the lower pivot jewel, just in case. As soon as I winded it up, it kicked to life getting some nice 300 degrees (slowmo vid uploading). Timing again: -200 sec/day. Well, at least I got to the minus side. The regulator was full on slow since it was running fast before. Moved it arround. +160. Getting there! After four or five more fine adjustments, I got close enough to zero. Take into account the measuring must not be the most accurate one, for sure. I'm planning on building an electronic one with a microcontroller, when I get some free time, and see what it comes out. Being an enthusiast and a begginer at the same time, I'm quite pleased with what I achieved today. I'll keep an eye on the timing of course, on the following days. As to the watch, it was at my father's, non working for years, so I got curious.

Thanks to everyone for the warm welcoming and replies!

Cheers

This sample ranged from +7 to +2. Again it's probably not the most accurate, we'll see after a couple of days.

The analized sample and the slowmo. If you'd like to see the video, the easy way probably would be to download it from the forum. The audio should play fine (at least it does on the preview).

A little update: After 6 and a half hours, side by side with my phone's cronograph, it's good by the second. So far so good. Why only six hours? Well, last night was odd since I had to pick up someone from the airport at 4 am, so I slept quite off schedule and forgot to rewind it. When I got up again it had stopped, therefore losing my reference from yesterday. I'm keeping track of it from now on!

      AS 554 from 1930

      Nice interesting diver Razz, i have a sheffield dress watch, different movement altogether. Could be a wrong motion works part, how does the setting feel before fitting the cannon pinion, clutch and intermediate wheel meshing ok ?  The less traditional setting design could be suspect, the second wheel has a slip clutch assembly, that most likely needs looking at. LA is 42 ° Razz Tbh i  much prefer to call the complete unit the lever, then use the seperate names for all of its components. Such as guard pin, fork, fork horns, fork slot, lever arm, pallets , pallet arms, pallet slot, pallet stones. I suppose pallet fork is the combination of the two opposite ends that make up the lever, its also called the anchor which is descriptive of its appearance.  Its a pretty basic 1930s  swiss lever movement H and yes Nev was meaning the pallet fork.

      The pallet fork should really be called a lever, English lever, Swiss lever etc but most people including myself call it a pallet fork.

      Seiko 6309a diver crown replacement

      By RichardHarris123 · Posted

      Seiko have case numbers, I  can't see it on your photos.  If you can find that we can look for a genuine crown.  If not, you need to measure the diameter of the stem, the distance between the lugs and the depth of the lugs.  The case number will be something like this.

      I'm not sure what kind of movement this is, but I'm curious to know if you're using the word "lever" as a synonym for "pallet fork"?

      Actually kind of rough, maybe munute wheel pinion problems? Is the 2.73mm canion oinion which seems rarer and not availble on Cousins UK. The seconds hand works and suprising nice amplitude but don't know the lift angle and BE this one says 17 j but is a pin pallet as well. Cap jewels on the escape and drive train pivots. Interestingly in has both water proof and shock resistant on the caseback and dial. Puts this around 1969 or '70? The double bezel that works independently is cool has the pi symbol on each. Wonder if it can be used like a slide rule ir something...
