The Tetra is most probably the most modern watch among the Nomos timekeepers, but what really first strikes the eye is the smooth and skillful mixture of color shades. The latest additions to the color collection are weltweiß (worldwhite), himmelbau(sky blue), biskuit and zartbitter brown(bittersweet). All share the same rhodium-plated hands, Horween shell cordovan straps and the manual-wind Alpha caliber with 43 hours power reserve.
