Panzera Aquamarine NATO Watch

Designed as much for office workers as it is for divers, the Aquamarine by Panzera features a cushion-style case that gives the watch a girthy 45-millimeter width. For easy legibility, the dial features long stick markers at the hour positions and exaggerated Arabic numerals—one red, one white—at the 12 and 6 o’clock positions. Also in the interest of legibility, the white skeletonized hour and minute hands are not only lumed but also oversized, while the seconds hand is tipped in red. At 3 o’clock is a day window and an extended date display.

The Aquamarine is fitted with Miyota caliber 820A automatic movement. Packed with 21 jewels, this Japanese movement vibrates at 21,600 beats per hour. It can be wound by hand, though it also offers automatic winding, which is powered by the wearer’s own movement. The day and date can be set by way of the double crown—which features a screw-down design—at 3 o’clock. For added water resistance, the caseback is also screwed down, helping the watch achieve a 200-meter rating. And for excellent scratch resistance, not to mention increased legibility, a sapphire crystal with double anti-reflective coating protects the dial.
