US customers, please contact the sales team.
The One Week Skeleton Rose Gold is a tribute to Mr. Armin Strom’s pioneering artistry in skeletonisation – a craft that lies at the core of the brand’s philosophy and heritage. For the first time, the in-house calibre appears in a solid 18K rose gold case, enriching the collection with a warmer character. Rose gold coloured finger bridges, hands and applied indexes mirror the tone of the case, while a sleek black textile strap provides a refined modern contrast. Measuring 41 mm in diameter, the case remains compact and ergonomic and its skeletonised architecture gives the watch a distinctive presence on the wrist – a harmonious balance of technical craftsmanship and precious metal elegance.
At its heart lies the hand-wound Calibre ARM21, a reinterpretation of our first in-house Calibre ARM09. Two mainspring barrels work in series to deliver a steady flow of energy for seven days, wound by two ratchet wheels visible on the dial side – a distinctive Armin Strom signature. Operating at 3.5 Hz, the calibre ensures consistent precision and stability in daily wear.
Inspired by the ingenious mechanisms of historical pocket watches, the conical power reserve mechanism is complemented by our 3-dimensional power reserve indicator, which displays the remaining energy with exceptional clarity and precision. Central hours and minutes keep the display symmetrical, while a skeletonised small seconds at 9 o’clock adds an engaging sense of motion.
Every component of the Calibre ARM21 is decorated by hand, reflecting Armin Strom’s dedication to traditional craftsmanship. The two finger bridges are coated in a rose gold tone that enhances the depth of the open worked construction without overpowering it. Hand-polished bevels, circular graining and finely finished screw sinks demonstrate the brand’s uncompromising attention to detail – The skeletonisation brings the movement to life. Each One Week is assembled twice, a hallmark of the brand’s commitment to mechanical precision and aesthetic integrity.
Limited to just 50 pieces worldwide, the One Week Skeleton Rose Gold continues Armin Strom’s modern gold chapter – a celebration of mechanical transparency, precision and craft.
