The size

We do not ask you. The atelier's archive knows the Aqua Terra 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. What size your reference takes is stated in the archive.

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 it needs to be; at the wrist it returns to its thickness. The calf lining, the edges painted in several layers, the saddle-stitching by hand.

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.

In 2008 the dial takes on vertical stripes; in 2017 the stripes become horizontal and the date moves to 6 o'clock. Lug width changes with the case: 16, 19, 20 or 21 mm.

The first Aqua Terra, 39.2 mm

In 2002 the Aqua Terra is released with the calibre 2500 and Co-Axial escapement; on the 39.2 millimetre case the lug width is 20 millimetres.
