Serial Number 40465867 was reported as inaccurate.

Note: Most post-1940's grade 387 have monometallic
balances - not expansion type. This watch
definitely has the mono type.
Curator Response: Thanks for the report. I have this balance change occurring around 1944, a few runs after this particular run. Images for #40465216 from this run also show an expansion balance. If your watch is fitted with the monometallic balance, please upload images for further evaluation. Thanks!
