Ruhla Space Control

Description

The Ruhla Space Control 4640M5 is an elegant men's watch that combines German watchmaking tradition with state-of-the-art solar technology. The striking dark red dial with sunburst finish is protected by scratch-resistant sapphire crystal, giving the timepiece a noble appearance.

Thanks to the precise Japanese solar movement, battery changes are a thing of the past, while the brushed stainless steel case ensures durability. With a water resistance of up to 10 bar, this watch is the ideal companion for demanding everyday life.

  • Sustainable Solar Drive: The precise quartz movement is powered by light energy, eliminating the need for regular battery changes.
  • High-Quality Sapphire Crystal: The extremely scratch-resistant glass reliably protects the dark red dial from external influences.
  • Genuine German Craftsmanship: This watch is manufactured directly in the traditional watchmaking town of Ruhla and stands for Thuringian craftsmanship.
