Serial Number 4720433 was reported as inaccurate.
be "Unmarked 60-Hour". The listing neglects that
the detail: Barrel - 60 Hr. Motor. A real world
test recently conducted on this watch demonstrated
that it ran for 58 hours and 23 minutes - not bad
for a 96 year old watch. From The Sangamo Special
- Beginning to End by Michael Chameleon
11-23-2006, it is stated that “(The Model 13’s
were all 60 Hour watches, however only the last
2200 were marked Sixty Hour)”. As I am planning
to sell the watch, the omission of these details
can have a huge impact on its value. It would be
greatly appreciated if the information be updated.
I thank-you in advance.
