The Eternity GMT is one of Stuhrling Original’s finest automatic timepieces. This watch features a 42mm case made from solid stainless steel with a beautiful polished finish. The guilloche solei texture on the dial is hydraulically stamped using vintage German machinery to capture the Old World style of watchmaking, and Arabic numeral 12 and shark’s teeth indices are each individually hand-applied. An ST-90072 automatic movement powers the Eternity GMT, which includes hours, minutes, and small seconds with a GMT window and big date – one of the most complex movements in Stuhrling’s repertoire! It comes equipped with an elegant and stylish alligator embossed genuine leather strap.
The Eternity Family is part of the Symphony Collection, and it includes beautiful timepieces that feature an incredible sunray dial.
Krysterna is proprietary to Stührling Original and refers to the crystals that are used in its timepieces. Krysterna stems from the eyewear industry and has more strength over a spread surface area than sapphire. Krysterna crystals are more scratch resistant than mineral crystals and more shatter resistant than sapphire crystals.
Summary of Features
• Movement: Automatic
Automatic watches do not operate on batteries. Automatic watches are made up of about 130 or more parts that work together to tell time. Automatic movements mark the passage of time by a series of gear mechanisms, and are wound by the movement of your wrist as you wear it. The gear train then transmits the power to the escapement, which distributes the impulses, turning the balance wheel. The balance wheel is the time regulating organ of a mechanical watch, which vibrates on a spiral hairspring. Lengthening or shortening the balance spring makes the balance wheel go faster or slower to advance or retard the watch. The travel of the balance wheel from one extreme to the other and back again is called oscillation. Lastly, automatic movements come in different types, including movements that are Swiss-made, Japanese-made, and more.
Also referred to as self-winding, watches with automatic movements utilize kinetic energy, the swinging of your arm, to provide energy to an oscillating rotor to keep the watch ticking. They're considered more satisfying to watch collectors (horologists) because of the engineering artistry that goes into the hundreds of parts that make up the movement. If you do not wear an automatic watch consistently (for about 8 to 12 hours a day), you can keep the watch powered with a watch winder (a great gift for collectors).
