A unique survivor from the mechanical watch era, the Agon 21 Jewels combines utilitarian reliability with mid-century design flair. Made in the era of hand-wound precision, this compact wristwatch features a bold, black textured dial with arrow indices, a red seconds hand, and a quirky vintage date window at 3 o’clock.

The dial carries the classic specs of the time—Waterproof, Antimagnetic, Unbreakable Spring—etched right into its surface. A Swiss mechanical movement beats inside, making it both collectible and functional.
