Product Details
Description
The Ruhla Space Control 4660M2 is a men's watch manufactured in-house in Ruhla, paying tribute to the historic space mission of Sigmund Jähn in 1978. The dial faithfully recreates the original brown dégradée design with silver numerals and indices, complemented by luminous hands for reliable readability even in low-light conditions.
The stainless steel case measures 40 mm in diameter and 13 mm in height, and is water-resistant to 10 bar. Powering the watch is the Japanese automatic movement Citizen-Miyota 8315, featuring 21 jewels and a power reserve of 60 hours. The high-quality sapphire crystal reliably protects the distinctive dial from scratches. The watch comes with an integrated metal bracelet and bears the quality hallmark "Made in Germany".
