I am very new to watch repair and need some advice. I am trying to repair a Waltham winder. I have the stem out but as you can see it is bent. My hope is to order a new stem, crystal, and crown, but I am not able to identify the proper replacement. The options are just too many. 

The stem length is 12.5 mm but is broken off. The crown diameter is 4.25 mm on a comparable Waltham but it is missing the gold plating. 

I would be most grateful if someone could point me in the right direction. Would Esslinger send the correct stem with the photo?

Thank you,

This is one of the Swiss Walthams, they used a lot of ETA movements. Hopefully you will be able to see the ETA mark and movement number under the balance wheel. Your movement photo is not clear enough nor zoomed in enough to see it here. Hopefully this will help get you on track as with a manufacturer and movement number it will be easier to search for parts.

This is an AS movement. Find its caliber NO on mainplate under the balance.

This looks esay to streighten, or you can replace the bent section with a stem extender.

Thank you for your help! The numbers under the balance are AS ST 1802 / 03. I have written Esslinger for part numbers on a new stem, crown, and crystal. 

If you have any other guidance, please let me know.  I also have a Waltham self-winder I was able to get working. 

The support on this forum has been most helpful. Attaching better photos.

 I'd say good job so far as I don't see any finger prints on this beautiful dial and it be shame if you end up having to remove it to access the keyless, you see sometimes the stem doesn't want to engage and lock onto the keyless mech (even if you had observed the proper proceedure for pulling  the stem out )

Surely you know, the set lever screw is only to be loosened about one to one and half turns, as it might release the set lever if you loosen it more.

Push on the set lever screw as you insert the new stem in and ( turn the stem a little as you are inserting the stem)  then tighten the screw, next pull the stem outwards to the SET TIME POSITION , you will by then know if the stem has engaged and locked onto the keyless or not. 

If it hasn't, pull the stem outwards before loosening the little screw, this will set/ leave  the keyless in The SET TIME position, then loosen the screw and pull the stem out to retry inserting the stem.

Hope I am clear to understand and this helps.

      9020 or HP500? Which would I get the most use out of?

      By Neverenoughwatches · Posted

      Depends what sizes of watches you mostly service . If you were to say pocket watches then you might benefit by wholly replacing the 9010 for 9020. As a rough guide hp500 is twice the viscosity of 9020 which is twice the viscosity of 9010 at 20°c.  So hp500 would give you a more mid-range oil between thin 9010 and HP1300, but as it happens hp750 is more mid- range than hp500, but is that more or less useful when oiling a train of wheels. After the barrel arbor the jump down in pivot size is around half, then after the centre wheel maybe more than half until the escapement. And pivot size isn't especially a deciding factor, as the torque and speed of a pivot would be more relevant when thinking about which oil to choose. So 750 might only be useful on a centre wheel and nothing else, and 500 might be better than 1300 for oiling the centre wheel but still comprises the rest of the train, where 9020 would be ok for the train but too thin for the centre wheel, leaving only 1300 for the oiling of it. You see the problem we're having here. What can be ok for one thing is less ok for another in a different way, damping down power compared to oil spread.  Maybe mixing a drop from two opposite range viscosity synthetic oils will give you some approximate thickness of an in-between . You want a short answer now ?  I tnink I'd go with the 9020. Now be prepared for a whole host of different answers.

      So, working on watches and your karma at the same time: win-win situation!

      @SteveF ,  Go on to Dr ranfft website,  Enter keywords Omega 26.5T3  ranfft .  There Dr ranfft  has listed all related calibers to this family, all which beat the same frequency,  any balance complete of this family fit your watch. This would only expenad your choice of balance complete.  Recolleting your hairspring is easy, but matching it with a balance of the family is challanging.

      Yes, it looks much better, but at this point the main thing is to make the spring in one plain. so picture from side will show this better. Now it is seen that #1 bending is needed, which is normal.
