··Oooo subtitles!If you look at the movement photo you posted above, the one on the yellow post it note, you can just about see it on the edge, towards the 8pm position. That pic isn't high enough resolution to check but maybe you have an original that is? Failing that, carefully unscrew the back, lift off the dust cover and with a camera or loupe take one yourself. But use care!
To be fair to your watchmaker, the serial numbers are often difficult to make out exactly even under magnification, but I am certain yours will be 26m not 20m unless there has been some major messing about with your watch.
