The polished finish adds a sophisticated touch that complements formal attire while remaining suitable for relaxed weekend wear.
• Scratch-Resistant Glass – The dial is protected by a robust glass that resists scratches and minor impacts, helping preserve the watch’s clarity and appearance through daily use.
