The Glashütte Original 1-36-13-03-90-33 combines the elegance of 18k red gold with the robust functionality of a professional diving watch. Its galvanic black dial features a refined sunray finish, creating a striking contrast against the gold case. Applied indexes and Arabic numerals, along with luminous hands and Super-LumiNova details, ensure clear legibility in varying lighting conditions. A date display and rotating bezel add practical functionality, while the overall design balances luxury with a distinctly sporty character. The 43mm round case is crafted from 18k red gold and measures 15.65mm thick. A sapphire crystal protects the dial, while the centrally screwed sapphire exhibition caseback provides a view of the mechanical movement. With water resistance up to 300 meters (30 bar), the watch is designed for professional diving. A black rubber strap complements the case and is secured with a folding buckle, providing a practical and comfortable fit. Powering the Glashütte Original 1-36-13-03-90-33 is the automatic Caliber 36-13, a mechanical movement that drives the hours, minutes, seconds, and date functions. Its automatic winding system supports convenient everyday operation, while the exhibition caseback offers an opportunity to appreciate the movement's mechanical construction. Bringing together precious-metal craftsmanship and serious diving capabilities, the Glashütte Original 1-36-13-03-90-33 stands out with its 18k red gold construction, black sunray dial, and 300-meter water resistance. The combination of a rotating bezel, luminous details, automatic movement, and rubber strap makes it a distinctive choice for collectors seeking a luxury sports watch with professional diving credentials.
