Research Note: This run is designated as Grade 345 in factory serial lists. However, examples of Grade 337 movements have been found in the run (marked "337" on the barrel bridge). The majority of the first half of the run has been determined to be consistent with Grade 345 while the second half is consistent with the 337 classification despite obvious overlap between these groups. The database has been segmented accordingly, but mixed results are still possible and expected. #534279 and #534299 Verified as Marked "337" (17 Jewels, Marked, Gilded Screws/Regulator, No Adjustments Indicated); #534046 Verified as Marked Grade 345.
