The two-cylinder model shown here was
rated at 10 horsepower, and weighed only 190 pounds; it
was priced at $250. Watertown also offered a three-cylinder
model, priced at $375. The four-cylinder, 20 horsepower size
retailed at $500. For racing purposes, the company could
supply their Type R engine that included an auxiliary air intake,
for an extra $12.50 per cylinder. We have found no
Watertown advertising aside from 1907 and 1908.
