It should be reliable with the st19 movement, but all of them have incorrect dial spacing(nothing can be done about it)I believe there should be an accent over the word tachymetre, and the dials don't look recessed, but if it comes with the Omega branded bridge as shown it's a definite plus. On these it all depends on what you will accept in the flaw department cause they
ALL have them of one kind or another. Good luck!
Here is my moonie with sunken subdials and accent but no Omega bridge:facepalm:
