Catalogue description

Dealer description — Craft & Tailored

Whether it's a chronograph, diving watch, or a simple dress model, a Longines wristwatch never seems to disappoint. Longines history is sprawling with an array of beautiful and functional watches, including from military-issued timepieces, unique dress watches, and beautiful sports watches. The Longines 30CH in-house flyback chronograph movement was created in 1947 and is the direct successor of Longines' legendary 13NZ movement created in 1936, which was the first flyback chronograph wristwatch to ever be produced and is renowned as one of the best movements ever created. The 30CH, however, is also regarded as an impressive and truly important chronograph movement in its own right, essentially representing the end of the truly in-house Longines chronograph movements before the brand moved to a modified Valjoux movement platform. SPECS Stock # LNG30CHRG Brand Longines Style Chronograph Model 7414 3 Serial 12XXXXXX Size Men's Material 18K Rose Gold Dial Silver W/ Red & Blue Accents Millimeters 36 Bracelet Original Longines Strap W/ Original Longines 18k RG Buckle CASE & BRACELET The noble 36mm 18K rose gold case is in beautiful original condition, exhibiting minimal evidence of previous polishing as the original case geometry remains intact with only gentle signs of use present. The case retains its original Longines-signed rose gold crown and square rose gold pump pushers. The case back also remains in clean condition and shows gentle, yet expected signs of previous wear. The watch comes supplied on a 2pc handmade leather strap. DIAL & HANDS The original silver dial is simply exceptional. The red and blue outer timing scales give the watch a welcomed touch of color, and the dial itself has achieved an even, warm coloration throughout. The only elements of real age present is only nominal in nature and exists at the very edge of the dial, with no effect to the actual aesthetic of the watch. The original rose gold hands also remain in exceptional condition. ACCESSORIES

Atlas type guide

Chronographs and split-seconds watches

A chronograph is a watch with an additional seconds hand that can be started, stopped and returned to zero independently of the timekeeping. Louis Moinet built an early example in 1816 and Nicolas Rieussec a recording 'chronographe' in 1821; Adolphe Nicole's heart-shaped reset cam (patented 1862) made the modern return-to-zero possible. Split-seconds (rattrapante) chronographs add a second hand that can be stopped for intermediate times; flyback chronographs restart instantly.

Chronographs were essential tools for doctors (pulsometer scales), artillery (telemeter), engineers and sport. In wristwatches, Valjoux, Venus, Lemania and later the automatic chronographs of 1969 (Zenith El Primero, the Chronomatic Calibre 11 group and Seiko 6139) are milestones.

What to look for

  • Push-pieces on the case band or a single button in the crown (monopusher).
  • Subsidiary registers for minutes and hours; tachymeter, telemeter or pulsometer scales.
  • Column wheel versus cam control visible in the movement.
  • Calibre markings of specialist makers (Valjoux, Lemania, Venus, Landeron).

Dating clues

  • Pocket chronographs with heart cam reset: after 1862.
  • Wrist chronographs: from c. 1910; two-button designs from the 1930s.
  • Automatic chronographs: from 1969.
