Seiko Prospex LX Line Diver’s Watch SLA039 – 8L55 Caliber | Professional 300m Saturation Diver

Engineered for the extreme, the Seiko Prospex LX Line Diver’s Watch SLA039 combines high-performance diving functionality with luxurious design. Powered by the high-beat 8L55 automatic movement (hand-winding compatible), this professional-grade dive watch beats at 36,000 vibrations per hour (10 beats per second) for exceptional precision and smooth sweep. With a power reserve of approximately 55 hours and +15 to -10 seconds per day accuracy, it’s built for reliability in the harshest environments.

Crafted from Ever-Brilliant Steel, the case offers enhanced corrosion resistance, making it ideal for saturation diving up to 300 meters (1000 feet). The robust 44.8mm diameter case features a one-piece structure, screw-down crown, and unidirectional rotating bezel for ultimate underwater performance.

A dual-curved sapphire crystal with anti-reflective coating on the inner surface ensures optimal legibility in all lighting conditions. Combined with LumiBrite on the hands, indexes, and bezel, this diver’s watch offers superior visibility during deep dives or nighttime use.
