Catalogue description

Dealer description — Craft & Tailored

Elgin was a watch company originating from Elgin, Illinois and was founded in 1864 under the name "National Watch Company" and officially became "Elgin National Watch Company" in 1874. The first wristwatch for Elgin came into production in 1910 and in the Second World War, Elgin produced both watches and military instruments for the United States Military. Unfortunately, Elgin disbanded in the year 1968. All US manufacturing discontinued and the Elgin name was sold. After the Elgin names initial sale, the name passed through several hands which resulted in some interesting pieces that were manufactured under the Elgin name from all over the world. Here at Craft + Tailored we love when a vintage watch has some vibe and style, and this Elgin Incabloc Chronograph doesn't disappoint. The metallic blue sunburst dial features flashes of gold, red, and silver speckled throughout from a natural patina, the minute register offers and complimentary pop of color with its regatta countdown timer, and the bright orange lollipop chronograph hand ties the whole dial together. The Unpolished case provides rugged sharp angles while the very unique brick-style stretch bracelet provides an element of subtlety. There's no doubt this Elgin chronograph is fun, but it's also worthy of the most prestigious watch drawers as it's powered by the revered Valjoux cal. 7733 chronograph movement.

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.
