Serial Number 235438 was reported as inaccurate.

Note: Serial number 235438, as mentioned in a previous
verification, is a pendant set model 5. This make
the grade of the watch a 281, not a 182.

Curator Response: Thanks for the report. However, there is no known description for a No. 281 that matches the characteristics of this movement. However, The "182 Special" is described in catalogs as two-tone, 17 jewels, adjusted, and pendant-set.
