The size

We do not ask you for it. The atelier's archive knows the Eco-Drive references one by one: the lug width, the case, the years. Below is what the archive says today; from the reference, the rest follows. The watch stays on your wrist.

What changes for the strap

The end of the strap follows the profile of the case between the two lugs. The archive tells you what size your reference has.

The leather

Alligator, box calf, suede, shell cordovan: the leather is chosen together, in the atelier or by video call. Where it enters between the lugs, the strap is as thin as needed; at the wrist it returns to its thickness. The calf lining, the edges painted in several layers, the hand stitching in saddle stitch.

The time

Four, five weeks from confirmation. In the atelier in Via XX Settembre or by video call, wherever you are. Care for the first eighteen months is included.

The next step

The right strap is not chosen. It is built together.

Four models

Eco-Drive is Citizen's light-powered charging, not a model. It was born in 1976 with the Crystron Solar Cell, the first analogue quartz watch powered by light; Citizen later developed the technology now called Eco-Drive. With a full charge an Eco-Drive runs for 6 months.
