Serial Number 826415 was reported as inaccurate.

Note: this movement is 'hunting' configuration. You are
showing the end of the SR block (for grade 935) to
be 826500. I believe the change from 935 (open
face) to Grade 835 (hunting) started sooner as
this watch 826415 is a Grade 835 . all other
specs are the same for both grades. [listed as
item # 371690596687]
Curator Response: Verified to be 18-Size Model 10 (Hunting), Grade 835. I have modified the runs to split at X400. [eBay #371690596687]
Changes since this report was submitted:
