Citizen Eco Drive Blue Angels Skyhawk Men's Analog Digital Watch Stainless Steel World Time

The C650 movement is part of Citizen’s Eco‑Drive range—solar-powered quartz calibers introduced in the mid-2000s, offering chronograph, alarms, UTC, countdown timer, perpetual calendar, and dual time functions.

The Eco‑Drive technology itself originated in the early 1990s and was launched globally between 1995–1996. It allowed light-powered watches with concealed solar cells under the dial—charging from any light source and storing power for months, sometimes years.

Citizen has partnered with the U.S. Navy Blue Angels demonstration squad for over 25 years. This collaboration began with the Navihawk model and evolved into the Skyhawk with Eco‑Drive features around 2002 and later versions with Super Titanium, radio-controlled timing, and refined styling .

The C650‑T000959 is part of this lineage, combining high-tech functionality with aviation-themed aesthetics tied to the Blue Angels.
