Hand-Wound. Heartfelt. Timeless. Crafted for those who appreciate the beauty of traditional watchmaking, the Worldmaster Prestige ATL-4 Limited Edition combines timeless elegance with the rewarding experience of a hand-wound mechanical manufacture calibre. Limited to just 188 pieces worldwide, it offers a rare opportunity to own a watch created for collectors who value craftsmanship, character and enduring design. [vc_row][vc_column][vc_column_text css=”” css_params=””] A Celebration of Mechanical Craftsmanship The Worldmaster Prestige ATL-4 Limited Edition celebrates mechanical watchmaking in its purest form. Limited to just 188 individually numbered pieces, this exceptional timepiece is powered by the hand-wound Atlantic Manufacture Calibre ATL-4, developed from the renowned ETA 6497/98 and enhanced according to Atlantic’s own requirements. Every turn of the crown creates a direct connection between owner and movement, transforming the daily act of winding into part of the experience itself. The elegant silver dial features a refined Côtes de Genève finish and reveals selected elements of the movement through its distinctive double open-heart design. The balance wheel remains visible through the aperture at 9 o’clock, while a second opening at 6 o’clock provides an additional view into the movement beneath. Together, they bring the mechanics of the watch to life and create a constant reminder of the craftsmanship within. Behind the dial, specially developed balance bridges, a Glucydur balance wheel and a Nivarox hairspring contribute to the precision and character of the ATL-4 Manufacture Calibre. Visible through the sapphire crystal caseback, these details showcase the attention devoted to every aspect of the watch. Presented on a polished stainless steel bracelet and accompanied by an additional black leather strap, the Worldmaster Prestige ATL-4 adapts effortlessly to different occasions while retaining its unmistakably classic character. Created for collectors, enthusiasts and lovers of traditional Swiss watchmaking, the Worldmaster Prestige ATL-4 Limited Edition is a tribute to craftsmanship, heritage and the enduring fascination of a mechanical movement powered by hand.
