The bottom of a random, semi-functional Swiss level, under the steel bar, one can see the Maltese-Cross stopwork, and two steel 'jewels' at approx. 12:30. These match real jewels on the top(visable) side of the movement, and were common in 19th century Swiss watches, when they were making cheap, deceptive movements. More disturbing is that these are on the Lever and the escape-wheel, which move the fastest and therefore have more need of jeweling. The intersecting arrcs that appear near the pivot in the middle and the 2nd wheel at about 3:15 are traces of the depthing tools used in laying out the movement. At the top(11:45) one can see the bottom cap jewwel of the balance, and it is cracked, which causes the watch to not run for any length of time when placed face down; it runs fine face up. If you want a Huge(2344x2344) version is available.
