Accuracy:-15/+25 seconds per day Calibre:6R5H Mechanical Manual Winding Power Reserve:72 Hours Jewels 24 Product Description : This Timekeeper style Presage Craftsmanship model pays homage to Seikos vast history in timekeeping and the pocket watches created at the time of the Seikosha establishment as it was then known in the late 1800s. This design recreates the dial of the very first Seikosha pocket watch, known as the Timekeeper, launched in 1895. Under a dual-curve sapphire crystal glass is a white enamel dial, lined with a railtrack design around its circumference, accented by roman numerals inspired by the original Seikosha pocket watch. From a distance, the slim and stylish nostalgic numerals seem like baton indices, increasing legibility even further whilst the stainless steel case of this craftsmanship piece is finished with a super-hard coating for increased scratch resistance. The accompanying black calf leather strap is sourced and certified from a LWG-certified tanner. The Leather Working Group is an international certification organisation that aims to create a sustainable leather production environment. Powered by an in-house crafted 6R5H automatic calibre, the timepiece has a 24-hour feature at 6 oclock. Accurate to -15/+25 seconds per day, it has a power reserve of three days. Seiko Presage: Timeless looks, precise mechanical timekeeping. Minimalistic watch designs with a distinctly Japanese aesthetic. *This enamel watch dial is manufactured by firing it at a high temperature. The process of melting enamel may create small dimples, tiny dots, and a rough surface. These attributes are unique features of genuine enamel watch dials, of which no two are exactly alike.
