The Porsche Design by Eterna Heritage Chronograph (Ref. 6625.41) is a highly collectible 1990s neo-vintage timepiece featuring a rugged Swiss mechanical movement wrapped in a functional, minimalist automotive design.

• Movement: Powered by the legendary Swiss-made ETA Valjoux 7750 automatic caliber, utilizing a 25-jewel design and an Eterna-signed rotor. 

• Dimensions: Features a 40mm case diameter (excluding the crown), a compact 43mm lug-to-lug distance, and a robust 14.5mm case thickness.

• Dial Layout: Designed with a striking black dial accented by three grey sub-registers (recording hours, minutes, and continuous seconds), an inner tachymeter bezel, a bright red central chronograph hand, and convenient day/date apertures at the 3 o'clock mark. 

• Material & Construction: Built from a full satinized stainless steel circular case and matching integrated bracelet with a branded folding clasp. 

• Crystal & Caseback: Outfitted with scratch-resistant sapphire crystal protection and a secure, screw-down stainless steel caseback for water resistance.

• Vintage Distinctions: Early production versions from the 1990s feature original tritium luminous markers (denoted by the "T SWISS" stamp at 6 o'clock) that age into a warm vanilla patina over time.
