This elegant timepiece features a vertical rectangular case paired with a soft gray dial and gold hands. A thin gold line surrounding the dial adds a subtle touch of glamour, while the minimalist design exudes a sense of sophisticated composure. The delicately faceted glass adds a refined touch, making this a watch that will elegantly complete any look, from suit styles to weekend attire.

Credor is a luxury dress watch brand proudly launched by Seiko in 1974. True to its name, which means "golden crest" in French, the brand has pursued a uniquely Japanese aesthetic and delicate watchmaking craftsmanship. Without relying on excessive ornamentation, this is a quintessential Credor piece that expresses quality through its materials and form.
