Key Features

• 43mm Square Brushed Stainless Steel Case: The bold square shape gives the watch a distinctive geometric profile, while the brushed finish reduces visible scratches and adds understated sophistication. Its 10mm thickness ensures a low, comfortable fit that slips easily under cuffs.
• Integrated Stainless Steel Bracelet: Seamlessly connected to the case, the bracelet enhances the watch’s streamlined silhouette and provides a cohesive, high-end appearance. The design eliminates traditional lugs, contributing to a sleek, modern aesthetic.
• Sunray Dial in Black, Green, or Blue: The dial features a subtle sunray texture that catches light dynamically, adding depth and visual interest. Available in three versatile colors, it pairs well with both neutral and bold wardrobe choices.
• Polished Baton Markers and Framed Date Window: Clear, polished hour markers ensure quick readability, while the framed date window at 3 o’clock adds practical functionality without disrupting the dial’s symmetry.
• Luminous Hands and Indices: Essential for low-light visibility, the luminous coating on the hands and markers allows for easy time reading in dim environments, such as evening commutes or nighttime events.
• Flat Mineral Crystal: Provides scratch resistance and clarity while maintaining a flat, glare-minimizing surface that complements the watch’s clean design.
• Signed Crown and Engraved Caseback: The crown features the Stuhrling logo for a branded touch, while the engraved caseback adds a refined detail that speaks to the watch’s craftsmanship.
• Quartz Movement: Delivers precise, reliable timekeeping with minimal upkeep, ideal for daily wear and those who prefer consistent accuracy over mechanical complexity.
• 5 ATM Water Resistance: Protects against everyday exposure to water, including splashes, rain, and brief surface swimming. Not suitable for diving, snorkeling, or high-impact water activities.

Prolonged exposure to water, steam, or extreme temperature changes may compromise its integrity. For warranty details, customers are directed to the manufacturer’s official support page.

Always store the watch in a dry place when not in use and avoid contact with harsh chemicals or abrasive materials to preserve its finish.
