Is anyone familiar with the Original 2824 or 2824-1? Specifically the date change mechanism/spring? I've only worked on a 2824-2 previously and can't find any documentation for assembly of the above.

 

Thank you

The base is the same in variants of the caliber, I take pictures as you turn down specially of the date mech that you are not familiar with, this will not only help during assembly it also is a gallary to refer to and show how things were, where you might come face an issue,  if a datasheet exist,  it will be found.

Tell as much as you know of the history, issues etc.

Good luck.

Unfortunately, like an idiot I didn't document during disassembly and it was too late by the time I realised it was an earlier variant. 

I've circled the area I'm having trouble with, it's where the calendar click would usually go on a 2824-2.

Thank you for that, just found that thread and looked through his disassembly photos, unfortunately it's a slightly different date change mechanism on the movement I'm working on, can't seem to find any pics online at all!

Missing part number 2555.

These original 2824 docs say it's part number 2556 for the date wheel, is that in place of 2555?

I can't work out how the jumper spring (part #2575) fits.

2575 fits behind 2576 to push it into date disk "detent". 

A picture worth a thousand words, isn't it.

I've got 2576 in the right place I think, I tried to fit 2575 where I've drawn in blue pen, it was tight but went in and then snapped so I've either put it in the wrong place, been too heavy handed or the part was worn as it's from a circa 1970's rotary.

I've ordered a replacement part from ebay.

I've now got a replacement spring (2575) if anybody knows how to install it?

      Diy rotary cleaning machine

      By Neverenoughwatches · Posted

      To add to this unusual cleaning idea, there is another type of device whereby the internal spinning parts that move through the fluid are not physically connected to the motor.  The internal whisk is propelled via a magnetic connection, so no damaged gaskets due to solvent contamination.

      Etachron regulation system

      By Mercurial · Posted

      Did you watch the whole video? Once Alex has set the stud, he first corrects the best error, then checks that the hairspring coils are breathing concentrically, then turns the stud to centre the hairspring between the open regulator pins.  He then checks that the regulator can traverse the terminal curve without disturbing the hairspring. A correction is needed, which he performs.  He then reinstalls the balance and re-centres the hairspring between the regulator pins, and verifies that the regulator traverses the terminal curve without disturbing the hairspring.  Finally, he demonstrates how to close the gap between pins.  He then recaps the whole process, fleshing out more detail. If you follow this process, you have correctly set up the regulator pins, and are ready to set the rate of the watch.  If you are interested in learning more about the effects of the regulator pin spacing on positional rates etc, you can read any literature regarding regulator pins. The etachron system makes adjusting beat, centering the hairspring between the regulator pins and adjusting the gap between the pins very convenient, but the same rules that apply to old style regulator pins apply to the etachron system.  This video explains the basics :    I hope that helps, Mark

      By Klassiker · Posted

      Some photos of the angles you are talking about, and the changes you are seeing to coil spacing etc. would be really useful. Part of your problem could be that you are closing the pins too far and pinching the hairspring. Adjusting the pin separation should not affect amplitude. Nor should it change the coil separation.

      Rolex cal. 3135 issues

      By VWatchie · Posted

      Did you try it on a Rolex ref. 16600 specifically? Congrats on the nice condition of the movement in your watch. Even so, remember to check the rotor play or those marks around the main plate may start to build up.
