Citizen Zenshin Senkei Titanium Steel Strap Men Watch CA4690-51A

Zenshin - in Japanese, this means progress, improvement or advancement.  This was precisely the aspiration behind the world's first titanium watch, which Citizen presented in 1970.

And it was this same philosophy that led to exceptional manufacturing expertise and in-house developments such as Super Titanium™ and Duratect over the following 55 years. 
 
At Citizen, these in an especially durable watch made of titanium are suitable for everyday use - they are light, hypoallergenic, robust and scratch-resistant.  

This year's chronograph models in Super Titanium™ also feature more edges, a new dial design and a new size. Senkei in Japanese means “clear lines”. They are available in black, blue, green and white. The diameter is 41 mm.
