This timepiece is a prime example of Seiko's continuous innovation in dive watch technology. The watch utilizes the sophisticated Kinetic movement (Caliber 5M63), which generates its own electrical power via a rotor (similar to an automatic watch), storing it in a capacitor to drive the quartz accuracy. The watch features a Power Reserve Indicator (the button at 2 o'clock, typical of the 5M series) that shows how much energy is stored, blending the convenience of quartz with the engaging aspect of mechanical winding.
The watch is built for serious professional use, featuring a 200m Air Diver rating and a unidirectional rotating bezel. Crucially, the entire watch (case and bracelet) is constructed from Titanium, making it incredibly lightweight, hypoallergenic, and highly resistant to saltwater corrosion- ideal for a professional scuba watch. The dial has a unique textured, speckled grey finish which complements the matte titanium case. The serial number 905427 suggests a production date of May 1999 (based on the first digit '9' and the second digit '0' for the month). This is an outstanding piece for a collector who appreciates cutting-edge hybrid technology and a professional-grade tool watch.
