Key Features

• NH35 Automatic Movement: Powered by the reliable Seiko NH35 caliber, this movement offers automatic winding through wrist motion, ensuring accurate timekeeping without batteries. It features 24 jewels and a hacking seconds function for precise time setting.

Benefits & Use Cases

This dive watch is ideal for professional and recreational divers who require a dependable instrument for underwater timing. Its 300-meter water resistance makes it suitable for scuba diving, spearfishing, and deep-water exploration. The luminous display ensures readability at depth or during night dives, while the sapphire crystal protects against scratches from sand, rocks, or equipment. Beyond diving, the watch serves as a durable everyday timepiece for outdoor activities, travel, or casual wear. Its automatic movement appeals to watch enthusiasts who appreciate mechanical craftsmanship and low-maintenance operation. The stainless steel construction resists corrosion from saltwater and humidity, making it a reliable companion for coastal adventures.

Important Notes

The STEELDIVE SD1957 is designed for water resistance up to 300 meters, but it should not be used for saturation diving or high-pressure underwater work. Avoid pressing the crown or buttons while submerged. Regular maintenance, including pressure testing every 1–2 years, is recommended to preserve water resistance. The watch comes in a protective package measuring 7.8 x 4.88 x 2.44 inches and weighs 12.63 ounces. Always ensure the crown is fully screwed down before exposure to water. Do not expose the watch to extreme temperature changes or strong magnetic fields, which may affect accuracy.
