The series of Longines Watches, which the company from Saint-Imier named Heritage, is meant to recreate its famous timepieces from the past, and to present them with the contemporary features that are enabled by the development of the technology. It is closely related to the past when Longines timekeepers were of immense significance to the various explorers and pioneers who used these watches in their feats and explorations on land, during the memorable flights and even in underwater adventures. These timepieces are proud examples of the watchmaker’s successful history.
All of the watches that celebrate the heritage of Longines are equipped with automatic mechanical movements which are placed in round casings, made of stainless steel or 18 karat gold 5N. The usual width of the housing is around 40 mm, but the collection does involve smaller watches (the diameter of 35 mm), and even some that are up to 47.5 mm wide. The most common colors of the dials are black, silver and white. These dials are protected with sapphire (which can be treated with single or several layers of anti-reflective coatings, or domed with additional scratch-resistance), synthetic and highly resistible Hesalite (which even allows the polishing of potential dents), and in one case with a mineral glass.
Speaking of available complications in these models, one can notice a great variety. There are models with three hands and only with date (in some instances there are small seconds indications, while the others have central second hands), some are column-wheel chronographs. Besides, there are timepieces that include full calendars with retrograde indications, second time zones, and even the ones that use radio signals to adjust the time. Few of Longines Heritage products are equipped with scales that allow their wearers to perform computing or navigation by the use of various scales, such are tachymetric, telemetric or Vernier. The flagship model of the series, which is a remake of the famous model made for Charles Lindbergh, even involves a bezel that enables the adjustments to variations of the time equation that occur on a daily basis.
The usual water resistance for the watches in the Heritage line is 30 meters, but there is also a diving model that can be submerged to 300 meters below the surface. Usually, wristlets used in the series are made from brown or black leather (mostly alligator), while the diving model has a synthetic strap.
