One of the latest timepieces in Stuhrling Original€s collection to bear the Delphi name, this watch comes with many unique features. The concentric circle cutout of the dial exposes the ST-90089 automatic movement, allowing the wearer to see the jewels, engraved scrollwork, as well as the balance wheel and mainspring. The dial itself features Cotes de Geneve patterning framed by a polished castle-style bezel. The dagger-style hands are filled with Luminova for easy read in the dark. This Delphi is equipped with a comfortable and stylish alligator embossed genuine leather strap.

Krysterna Crystals

Krysterna is proprietary to Sthrling 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.

The Delphi Family belongs to the Classic Collection, and they include timepieces that feature mechanical and automatic movements. Many of them also utilize an exquisite triple step design bezel.

Summary of Features

€ Movement: Manual/Self-Winding Mechanical Movement

The hand-wound mechanical movement is perhaps the most classical of movements. It operates exclusively by the daily (or sometimes more often) winding of the crown to power the mainspring (the €œheart€ of the movement). Unlike its automatic mechanical counterpart, this type of movement does not feature a rotor. The energy source is the mainspring (a spring coiled into a tight spiral) which is wound manually by the wearer twisting the crown, usually in a clockwise direction. As time progresses, the spring begins to uncoil, releasing the energy needed to activate the various wheels and make the movement tick. Without routine winding of the crown, the hand-wound mechanical movement will eventually lose power. Thus, mechanical hand-wound movements usually require daily winding. A hand-wound movement requires greater care than almost all other types of movements because once the mainspring is fully wound, additional tension may cause it to break.
