Serial Number 9586003 was reported as inaccurate.

Note: Serial number 9586003 has the winding stem at the
12 O'clock position, instead of at 3. The gold
case is made by B.&B. Royal Warranted 20 Years,
and has serial number 9521038. I inherited this
perfectly running pocket watch from my maternal
grandfather, who bought it new in 1900. For an
all original 119 year old watch, it keeps
excellent time and runs perfectly!
Curator Response: Thanks for the report. The lookup information indicates the watch is an open face configuration, as you stated. Did you see anything that needs to be updated with the information provided?
