Seiko SOLAR V138-0AD0 Ladies Day-Date Gold Trimmed White Dial with Gold Stylish Ⅻ-Ⅵ Roman Figure simple bar indexes and 3 hands Dial Day-Date Calendar, Stainless Steel, Good Condition KQ222 Model Background and Features: The V138 Movement is a solar-powered system that evolved from the golden age of quartz watches. This V138 solar-powered movement watch is often referred to as a model of evolution process from the golden age of quartz watches. V138-0AD0 belongs to the modern affordable solar dress-watch generation that Seiko produced for the domestic Japanese market (JDM) during the late 2010s–2020s. It sits in the same family as the Seiko Selection / Spirit Standard ladies’ solar lineup: clean Roman numerals, slim case proportions, practical day-date display, and maintenance-friendly solar charging. The model of white dial, gold-trimmed bezel, Roman XII–VI markers with bar indexes matches the elegant “business casual” styling Seiko heavily promoted in the Reiwa-era office-watch market for women. The design philosophy is presented in classic Roman numeral elegance, low-maintenance solar movement, lightweight everyday wear and conservative Japanese office aesthetics. During the 2000s–2020s, Seiko aggressively expanded solar quartz technology into affordable daily watches. Instead of targeting only luxury buyers, Seiko positioned solar watches as “battery hassle free,” environmentally friendly, highly accurate and ideal for daily commuters. The V138 family became one of Seiko’s core ladies’ solar calibers because it allowed thinner cases, long power reserve, day-date complication, affordable manufacturing cost and excellent reliability. This period also marked Seiko’s transition away from older disposable quartz modules toward rechargeable capacitor/cell-based solar systems. This movement is widely used as Seiko's standard quartz movement and is characterized by a good balance of reliability and ease of maintenance. It is a gentle presence that accompanies you in your daily life, and it is a watch that quietly embodies Seiko's philosophy of "practicality and reliability."
