Armin Strom launches One Week Manufacture Edition
A hand-finished versatile sports timepiece, with an open worked dial, a power reserve of 7 days, and an integrated bracelet. It is limited to 100 pieces.
Armin Strom has just launched the One Week Manufacture Edition. It reimagines the One Week, Armin Strom’s first-ever calibre from 2010, and celebrates 15 years of being a vertically integrated watchmaker.
The One Week Manufacture Edition is a versatile sports timepiece with a stainless steel case and integrated bracelet. It features an open worked dial, highlighting calibre ARM21, the new hand-finished haute horology movement. It has a power reserve of 7 days.
“The new One Week Manufacture Edition completely reimagines this milestone calibre (One Week from 2010) in line with the brand’s recent bolder, more three-dimensional approach to calibre design, all in a sleek and serene execution that further highlights its ingenuity and uniqueness. The mainplate, bridges and parts, visible on the dial thanks to the openworked movement design, are anthracite PVD coated for a striking look.”
The One Week Manufacture Edition is the second redesigned One Week model. The first was the One Week First Edition, launched in 2023.
“Collectors who missed the opportunity to get a first edition of the redesigned One Week will now have another chance. The Manufacture Edition of the new One Week will be limited to 100 pieces.” Serge Michel, Founder of Armin Strom.
