What is an automatic watch?
An automatic watch runs without a battery — it charges itself through the natural movements of your wrist. As long as you wear it daily, it keeps ticking. If left unused for more than 42 hours, it will simply stop and start again as soon as you wear it or gently wind the crown. This type of mechanism, rooted in traditional watchmaking craftsmanship, is more intricate and refined than a standard quartz (battery-powered) movement.
Why choose Proseiko?
Because we combine the reliability of genuine Seiko movements with premium materials and custom designs — all hand-assembled and tailored to your style. At Proseiko, you get the craftsmanship of a luxury watch, the freedom to personalize it, and a fair price without compromise.
