Introduction Offered here is a SEIKO Kinetic Auto Relay men's wristwatch, reference 5J22-0A50. This model features a black dial, luminous-style hour markers and hands, a date display at approximately 4 o'clock, a stainless-steel case and bracelet, and a sporty diver-inspired design. The watch is powered by Seiko's Kinetic Auto Relay system, which generates electrical energy through the motion of the wearer’s wrist and uses quartz regulation for timekeeping. It is currently running, but its present operating condition indicates that maintenance should be considered. Historical & Collector Value SEIKO's Kinetic technology represents an interesting chapter in the brand's development of alternative-energy wristwatches. It combines a mechanically driven generating rotor with quartz-controlled timekeeping, creating a system that differs from both conventional automatic watches and ordinary battery-powered quartz watches. The 5J22 caliber belongs to the Kinetic Auto Relay generation. Auto Relay was developed as an energy-saving system designed to reduce power consumption during periods when the watch is not being worn. For collectors interested in Seiko's technical history, the 5J22-0A50 offers an interesting combination of Kinetic technology, a sporty late-20th-century design, and a distinctive black dial. This example is offered with full disclosure of its current charging-related condition. Specifications - Brand: SEIKO - Model: Kinetic Auto Relay - Reference: 5J22-0A50 - Movement: Kinetic quartz - Caliber: 5J22 - Display: Analog, three hands - Functions: Hours, minutes, seconds and date - Dial color: Black - Case material: Stainless steel - Bracelet material: Stainless steel - Case width: Approx. 37 mm excluding crown - Case thickness: Approx. 11 mm - Wrist circumference: Approx. 17 cm - Accessories: None stated - Included items: Only the items shown in the photos Condition This is a pre-owned watch with visible signs of previous use. The watch is currently running. However, the seconds hand advances in two-second intervals. When the watch is shaken thoroughly, it temporarily returns to normal one-second operation, but after some time it returns to two-second intervals. This behavior suggests that the rechargeable energy-storage component / capacitor may have deteriorated. The watch is therefore offered in its current condition with the expectation that inspection, capacitor replacement, or other maintenance may be required. Time setting is possible. There are scratches and scuffs on the case, bracelet, buckle, and bezel. The crystal has visible linear scratches. There is also rubbing and tarnishing / dullness around the lower part of the case. Please check all photographs carefully for the exact cosmetic and functional condition. This is a pre-owned / vintage watch. It has signs of use such as scratches, small marks, fading, and wear due to age. Please check all photos carefully, as they are an important part of the description. The watch is running at the time of listing. Time setting and basic functions have been checked unless otherwise stated. Long-term accuracy has not been tested. As this is a used/vintage watch, maintenance or overhaul may be required after purchase. Water resistance is not guaranteed, even if the case or dial has water-resistance markings. Only the items shown in the photos are included. If box, papers, spare links, or accessories are not shown or mentioned, they are not included. Please understand that the condition of vintage watches can be subjective. I describe the item as accurately as possible, but minor signs of age and use should be expected. Service History The watch is running at the time of listing. Time setting has been checked. The seconds hand currently changes between normal one-second operation and two-second interval operation depending on the available stored charge. No documented service history has been provided. Due to the current symptoms, inspection and possible replacement of the rechargeable energy-storage component / capacitor should be considered.
