SJE117J1

The Seiko Prospex SJE117J1 is a Marinemaster 1965 Heritage Diver’s Watch that brings classic dive-watch character into a compact modern design. Its 39.5mm stainless steel case offers a balanced size for everyday wear, while the box-shaped sapphire crystal adds durability and a clear view of the dial. An anti-reflective coating on the inner surface further improves readability.

Inside, the watch is powered by Seiko’s Caliber 6L37 automatic movement with manual winding. It provides approximately 45 hours of power reserve and operates at 28,800 vibrations per hour. The movement also includes a stop-seconds function for more precise time setting.

Built for diving, the SJE117J1 offers 200-meter water resistance. Its unidirectional rotating bezel and screw-down crown add dependable protection, while LumiBrite on the hands, indexes, and bezel helps with visibility in darker conditions. The see-through and screw case back also gives the watch a distinctive finishing touch.
