Citizen Eco-Drive Super Titanium CA7090-87L Men's Watch Blue • Sapphire Crystal • Solar Chronograph

The Citizen CA7090-87L is an impressive men's chronograph from the Eco-Drive Super Titanium collection, a timepiece that combines high-tech materials with sustainable solar power. The 43 mm wide and 11 mm thin Super Titanium case features Citizen's proprietary Duratect surface treatment, making it five times harder than conventional stainless steel while being approximately 40% lighter — ideal for demanding everyday wear on the wrist. The two-layer blue dial with a vertically brushed surface and circularly grooved subdials gives the watch a sporty yet elegant character.

The CA7090-87L is powered by the Citizen calibre B642, a precise solar movement based on Eco-Drive technology that charges from any light source and, with a full charge, continues to run for up to seven months in complete darkness. The integrated 1/5-second chronograph with 60-minute measurement and a convenient date display make this watch a versatile companion for sport, travel, and the office. A sapphire crystal reliably protects the dial from scratches, and water resistance to 10 bar ensures confidence when swimming and snorkelling.
