Where 1769 fits
Why 1769 is special
Watt did not invent the steam engine; he made it roughly three times more fuel-efficient by keeping the cylinder hot and condensing steam elsewhere. That efficiency is what made steam power viable away from coalfields, which is the step that industrialised everything else.

Newcomen's engine of 1712 worked only where coal was free; Watt's separate condenser in 1769 made steam power economic anywhere. Sixty years separate the demonstration from the general technology.

Watt did not invent the steam engine. His separate condenser made it roughly three times more fuel-efficient by keeping the cylinder hot, and that efficiency is what let steam power operate away from coalfields — the step that industrialised everything downstream.
