This outstanding personality has earned his fame by virtue of his brilliant invention: a timekeeper, capable of complementing the plane’s on-board chronometers with a special mechanism for synchronizing watches to the closest second with help of a radio time signal with no need to move the hands.
The Weems Second-Setting watch incorporates the following functions: hours, minutes and seconds. Animating them is a self-winding movement - L699 / ETA A07 111 calibre, set with 24 rubies. It features a balance wheel, beating at the rate of 28,800 vibrations per hour. The movement boasts a 46-hour power reserve.
The Longines watch is available with an impressive case, which measures 47.50 mm in diameter. The front side of the case is protected by a sapphire crystal. The case back is fitted with an engraved, individually-numbered cover, which opens onto a sapphire crystal.
Performed in lacquered white, the timepiece face reveals a silvered opaline mobile central dial. Blued steel hands are traveling over large Arabic numerals.
The Longines Weems Second-Setting watch, reviewed by Watches.InfoNIAC.com, is mounted on a brown alligator leather strap, equipped with a Charleston buckle and an extension piece.
