The measurement

We do not ask you for it. The atelier’s archive knows the Datejust 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 strap takes the place of the bracelet and its end links, and the tip follows the profile of the case between the two lugs. The archive tells you the lug width of your reference.

The leather

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

The time

Four to five weeks from confirmation. At the atelier in Via XX Settembre or over a 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.

Datejust 36: four generations

The Datejust was born in 1945 with reference 4467, in yellow gold on the Jubilee bracelet presented together with the watch: it is the first automatic with a date that changes on its own in a window. The case has been 36 mm since the beginning and, from the 1601 to today's references, has a 20 mm lug width; in 2009 the Datejust II brings it to 41 mm, with a 21 mm lug width.

The 1601

The 1601 has a 36-millimetre case, a plexiglass crystal and, on early examples, the dial known as pie-pan; the date does not yet have quickset. Lug width, 20 millimetres.
