This watch combines a black 316L stainless steel case with a gold skeleton dial and a black top-grain leather strap. The openwork dial reveals the automatic mechanical movement under a sapphire front crystal, and a mineral exhibition back gives a clear view of the mechanism. Metal, glass and leather combine for a clean, modern look with visible mechanical detail.

• Material Quality: Nickel-free 316L stainless steel case and sapphire front crystal resist wear and help prevent scratches.
• Comfort Fit: Smooth top-grain leather strap with finished edges for comfortable daily wear and a secure fit.
• Practical Function: Seagull ST1646 automatic mechanical movement winds with wrist motion. The skeleton dial and mineral exhibition back make the movement easy to observe.

On the wrist, the black case frames the warm gold skeleton, creating a strong contrast that feels technical yet refined. The adjustable, replaceable leather strap adapts to different wrist sizes and pairs neatly with smart-casual and business-casual outfits. The visible movement adds mechanical interest without extra bulk.

A timeless addition to any watch collection.
