Timeless 40 mm analogue watch

This Citizen Eco-Drive watch uses a light-powered quartz movement, removing the need for battery changes. A blue dial with a date window at three o'clock sits inside a 40 mm stainless-steel case. The black leather strap fastens with a traditional pin buckle. It is suited to daily office wear and casual occasions.

Compatibility checks before ordering

Verify that a 40 mm case diameter and 9.3 mm thickness fit your wrist and shirt cuffs. The 16 mm lug width accepts standard replacement straps if you wish to change the look later. Water resistance is rated to 30 metres, so the watch handles splashes and rain but is not intended for swimming or diving. No charging cable or special tool is required for the Eco-Drive system.

Build quality and daily use

The stainless-steel case and bezel are polished to a silver tone and protect a mineral crystal dial window. A stationary bezel keeps the profile slim for sliding under sleeves. The leather band is sized for a men's standard wrist and will develop a patina over time. The pin-buckle clasp allows quick on-and-off adjustment without tools.

Questions about this item

Does the AW1780-09L come with the leather strap fitted or must I buy it separately?

The watch is supplied with the black leather strap already fitted and a buckle clasp; nothing extra is required to wear it.

How does the 40 mm case compare to the 9.3 mm thickness for daily comfort?

At 40 mm across and 9.3 mm thick the case sits low on the wrist, so it slides under a shirt cuff without catching.

What does 30 metres water resistance mean for real use?

It protects against splashes, rain and brief immersion such as hand-washing, but is not rated for swimming or showering.
