Founded in 1832 by Auguste Agassiz, Longines has built its reputation by producing exquisite chronograph movements and patenting the first flyback movement. Starting with the legendary caliber 13-ZN in the mid 30’s, Longines further continued its research and development and presented Cal 30CH, a new manual wind chronograph movement in 1947. The flyback function is a very important complication especially for aviators as it allows the wearer to reset the chronograph immediately without the need to stopping it first. Chronographs by Longines are considered to be amongst the best, most attractive and, consequently, collectable in the world. The present pink gold flyback chronograph from 1957 stands out with its absolutely stunning aesthetics, elegance and sobriety. The case looks much larger that its 36.5mm diameter suggests and has an extremely handsome presence on the wrist. Housing a caliber 30CH, the present watch is part of the timeless chronographs that built the brand’s reputation.
