Panerai · Automatic

OP III

A Valjoux 7750 with its chronograph removed. Panerai took the industry's most-produced automatic chronograph, stripped the timing works and left the base going train, which is why a three-hand Luminor carries the beat rate and 42-hour reserve of a chronograph movement. The result is unglamorous and extremely well understood — any watchmaker who has serviced a 7750 knows this movement.
