Armin Strom Tribute 1 Green: Refined Dress Watch With 100-Hour Power Reserve
Armin Strom has built a solid reputation in the world of independent watchmaking, particularly for its technical mastery and innovative approach to traditional haute horlogerie. While the brand is widely known for its complex Resonance and Masterpiece collections, it also offers a more accessible entry point to its craftsmanship through the System 78 collection. One of the highlights of this collection is the , a modern and refined dress watch with a striking green dial.
Elegant Case Design
The Tribute 1 Green stays true to the family’s compact proportions. Its case measures 38 mm in diameter and just 9.38 mm in height, making it perfectly suited as a slim dress watch. Crafted from stainless steel with alternating brushed and polished finishes, the case balances modern lines with subtle elegance.

Armin Strom’s signature design details are present: a small “lip” at 6 o’clock engraved with the brand name and an unconventional crown placement at 2 o’clock. The watch also shares its lugs with the Gravity Equal Force model, a nod to the modular design philosophy of the System 78 collection.
Striking Green Dial
The dial layout is minimalist yet intricate. Set against a frosted green background, the off-centered hours and minutes sub-dial immediately draws the eye with its hand-guilloché grain d’orge pattern in deep forest green. White Roman numerals on the surrounding frosted chapter ring add classical charm, while openworked hour and minute hands enhance the contemporary character.

A slender central seconds hand sweeps around the outer railroad-style track, and at the lower right sits the openworked mainspring barrel. This barrel is held by a mirror-polished, hand-beveled finger bridge and proudly engraved with “One Hundred Hours of Power Reserve.”
High-Caliber In-House Movement
Powering the Tribute 1 Green is the in-house manual-winding Calibre AMW21, just 4.20 mm thick. This movement showcases 97% in-house manufacturing. It incorporates Armin Strom’s patented equal force barrel, which ensures consistent energy delivery throughout the 100-hour power reserve.

A variable inertia balance beating at 3.5 Hz further contributes to stability and precision. True to the brand’s ethos, the movement finishing blends traditional techniques—like hand beveling and polishing—with a contemporary visual style.
Finishing Touches and Availability
Completing the package is a matching green Alcantara leather strap fitted with a stainless steel folding clasp. The strap is interchangeable, allowing quick swaps to suit different styles.

The Armin Strom Tribute 1 Green is produced as a limited edition of just 50 pieces worldwide, with a retail price of CHF 22,000.
