First service of Lady's watch


Recommended Posts

I've worked on a few mechanicals that size.  One of them that comes to mind was a little Kingston with an FHF-60, and another was a Seiko with a 4206B.  And that Seiko was crammed full: sweep second, automatic plus day and date, all in that tiny little package.  They aren't really much different to work on than larger movements.  Like you all mention, the small size is the main thing that presents challenges.  And I am sad, also, that some of these miniature marvels don't get more respect, and aren't in greater demand.

I do have a daughter, though, who adores the little cocktail watches.  She's seen the ones that I've worked upon.  I am looking for a vintage one that suits her, as a gift.  She will likely cherish it more than anyone else has in a long time.

Worked on a few ladies watches. Don't think I could do it if I didn't work under the microscope.

 One was the only Rolex I've serviced, a Cal 2230, 20mm dia. automatic. Gave me palpitations handling the balance 😨But it was a beautiful movement to work on. It's the only movement I've worked on that didn't need any adjusting after a service.

The hardest I've worked on is an Omega Cal 455, 16mm dia, automatic, with a sweep second. Very fiddly
I still have it, waiting for a new balance, as I trashed the hairspring trying to adjust it.
The hairspring is about 3mm diameter, so even with the smallest tweezers, it's not really possibly to tweak it (well not for me)

Just finished one of these movements in an Avia ladies watch.  Was impressed how well made the movement was.  All parts nicely polished and even had adjustable beat error on the regulator. Got really good amplitude and zero beat error after a bit of fiddling.  After letting it settle down through a full run time cycle (46 hrs!) and another full wind there was no discernable gain or loss over 36 hrs, very impressive. Not got any pics unfortunately.  Only downside was single top plate for barrel and gear train, so a little delicate fiddling required. I do  lot of ladies watches, small calibers, so now used to the very small parts.  Makes larger calibers seem massive afterwards!!!

    • Just to add to what @Neverenoughwatches says, the impulse jewel on the balance wheel is also held in by shellac, so avoid exposing the assembly to IPA as well - as stated the one-dip and generic tetrachloroethylene equivalent is safe with shellac so you can use this for your pallet fork and balance assembly. I agree, but worth noting that IPA readily soaks up water, even from the atmosphere: "IPA exposed to the air will absorb moisture rapidly until it reaches an equilibrium value of 65% IPA to 35% water." So you need to refresh it regularly.     
    • The width is otherwise known as mainspring height and strength as thickness for us more modern guys.
    • I've remembered something I had forgotten.  I've come across Dennison before but forgot all about it as I'm never going to use the units.  Maybe we should start a  thread on obscure units of measurement. 
    • Learned a new thing today! 🤓 Looked this up and found this informative document: Watkins-MainspringGauges.pdf
    • Correct one dip is expensive when the chemical is purchased as " one dip " which is why it is mostly reserved for these two small parts as far as information tells us it is mostly tetrachloroethylene. I use it bought as perchloroethyl used in dry cleaning processes, i cant say I'm overimpressed with it though it appears to me to be shellac safe. What may be a better solution for hairsprings is a high lab grade of pure benzine.  IPA is mostly used as a rinse and water displacer and yes it does have the potential to dissolve shellac, personally i would not buy anything that has significant water dilution so 99.9% IPA is the way to go. And lastly the part you are cleaning dictates your choice of cleaning brush, delicate parts like a hairspring requires the finest artist's brush you can find. Plates and bridges can take a little more scrubbing, but always check to make sure the surface is being unharmed. And dont forget a stick of tip benzine soaked correctly shaped pegwood is your mate set up for cleaning dirty jewels and removing stubborn dried up lubrication.
