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 the atelier in Via XX Settembre or by video call, wherever you are.

Three generations
The Aqua Terra enters the Seamaster family in 2002, with the calibre 2500 and Co-Axial escapement: no rotating bezel, 150 metres water resistance. 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.

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.
The vertical stripes, 41.5 mm
From 2008 the dial has vertical stripes; until 2017 the larger case measures 41.5 millimetres, with 20 millimetres lug width.
The 2017 case, 41 mm
In 2017 the dial stripes become horizontal and the date moves to 6 o'clock; the case is 41 millimetres, the calibre is the 8900 and the lug width is 20 millimetres.
