Introduced during the Art Deco era, the Curvex was revolutionary for its curved case construction, which required specially shaped movements and cases—an advanced technical achievement at the time. The result was not only improved comfort, but a watch that looked refined, architectural, and unmistakably elegant. This Tank-style Curvex features a slim, curved gold-plated case that hugs the wrist gracefully, paired with a balanced white dial and a classic small seconds display at 6 o’clock. The applied gold-tone markers and rectangular geometry reflect the clean, symmetrical lines characteristic of Art Deco design. The case back markings visible in the photos confirm the gold-plated construction and Swiss origin, while the gentle patina and minor surface marks add authenticity rather than detract from the piece. These signs of age tell the story of a watch that has been worn and appreciated over time. Today, Gruen Curvex watches are highly sought after by collectors for their historical importance, distinctive design, and timeless elegance. This example represents a beautiful entry into classic Art Deco watchmaking and remains perfectly suited for both collectors and refined everyday wear. Express Delivery Via UPS Express
