Serial Number 973223 was reported as inaccurate.

Note: Hamilton's 936 was their first watch produced and
made expressly for RR use. Serial numbers 1
through 426150 used a single roller. Staring with
no. 426151 in 1906 and continuing to the end of
production of the 936 with 1401000 a DOUBLE ROLLER
was used. 624301 saw the introduction of the MOTOR
BARREL, which continued to the end of production
also. The last few runs (like 973223) were fully
marked with "936", "Motor Barrel", and "double
Roller" all stamped on the barrel bridge. The
above information was obtained for Lloyd
Halligan's notes on Hamilton watch size and grade
production and remarks on the digitized serial
number look up data base at NAWCC.
Changes since this report was submitted:
Double Roller changed from No to Yes
