The Delphi Helix is a unique member of Stuhrling Original’s Delphi Collection. The solid stainless steel case features a triple step design bezel, which you can expect; the dial is where things get interesting. The skeletonization is done with a swirled whirlwind design, revealing the calibre ST-90050 automatic movement. Skeletonized hands indicate the individually applied Arabic numeral 12 and baton indices. The Delphi Helix has a stylish boardroom design that is further enhanced by the alligator embossed genuine leather strap.
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.
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 “heart” 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.
• Complications: Three-Hand Movement with Hours, Minutes, & Seconds
• Dial: Whirlwind-Style Skeletonized Dial
