• Two-Tone Stainless Steel Case and Bracelet: The combination of gold-tone and silver-tone stainless steel creates a versatile, modern aesthetic that pairs well with both formal and casual outfits. The bracelet features a secure clasp and smooth links, ensuring a comfortable, snug fit on the wrist while maintaining a polished appearance.
• 100m Water Resistance: Rated for depths up to 100 meters (10 bar), this watch is suitable for swimming, showering, and surface snorkeling. It’s designed to withstand water exposure during daily activities, though it should not be used for scuba diving or high-velocity water sports.

• LumiBrite Markers: Hour markers are coated with SEIKO’s proprietary LumiBrite material, which absorbs ambient light and glows brightly in dark environments. This ensures clear visibility during nighttime outings, early mornings, or in dimly lit spaces like theaters or restaurants.

Important Notes

This watch uses one nonstandard battery, which is included with your purchase. While it is water-resistant to 100 meters, it is not intended for scuba diving, high-speed water sports, or prolonged submersion under pressure. To maintain water resistance, avoid pressing any buttons while submerged and rinse the watch with fresh water after exposure to saltwater or chlorine. Regular cleaning with a soft, dry cloth will help preserve the luster of the stainless steel case and bracelet. For warranty information, please refer to the manufacturer’s official support page. The product arrives in standard packaging measuring 5 x 3.62 x 3.39 inches and weighs just 0.45 ounces, making it compact and easy to store or gift.
