Can someone help me with a size?

I believe it is 0X12X?? on the Dennison scale.
I don't see an 11SP- is this just an "11" caliber. It is the rectangular movement for a ladies watch. serial number is 5093. Do the swiss number by watch ebasche instead of sequentially out of the factory??

I beleive the size you are looking for is a 0x12x8 1/2
metric size 0.90x0.09 8 1/2 inches long
Samson #0126
I do havethis mainspring I have attached my post from 185
"Unknown Mainsprings.
Let me help identify your unknown mainspring.
Until the end of November send me a sample of your unknown mainspring and any info you have on the mainspring you need, along with a SASE.
Self addressed stamped envelope (mailer).
Include your email address just in case!!!!!!!!
This is an experiment I am conducting to see if this is feasible.
I will determine as closely as I can the mainspring that will fit your needs.
I will send it back ID'd for future use in your mailed, or return your money along with whatever info you supplied me.
The cost is $ 10.00 for the first spring, $8.00 for the second, and $7.00 for the third.
Any additional ones can be had at $5.00 each.
Cash or equivalent is the only payment that will get me started. This is an opportunity to get a mainspring and not spend the exorbitant dollars it would take to fix a watch.
Note these are mainsprings having standard ends.

Thanks Melvin,


I believe your are correct- Ordered one from Jules Borel as I needed some other supplies!!

Thanks again,

Michael
