Strap for Annual Calendar Chronograph 5960 Stainless Steel / Silver

No. The bracelet is integrated into the case with a proprietary attachment: no standard strap clips on without intervention. That is not a flaw — it is part of this watch's character. If you want to change it, I build the strap directly on the watch, in the atelier, to measure.

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>, at Via XX Settembre 15 in Milan. I bring the watch to the bench and take measurements from the case itself, not from a data sheet. Each lug end is shaped by hand to follow the exact geometry of the attachment. It is the only way to achieve a visual continuity that makes sense on a watch like this.

For a watch with this dual character — sporting in its aesthetic, technical in its mechanics — I choose naturally aged Barenia. It starts firm, almost stiff, and over time softens and takes on the marks of the person who wears it. It suits a watch that has nothing to prove.

With a first-quality leather and minimal care, five to eight years are well within reach. The upkeep is straightforward: keep it away from direct water, let it breathe between wears. The leathers I work with do not deteriorate — they transform, developing a patina that reflects the time of whoever carries them.

A flyback chronograph lets you reset and restart the count in a single gesture, without stopping first. On a watch that also carries an annual calendar — self-correcting for eleven months out of twelve — the result is considerable mechanical complexity handled with a steady hand. Patek launched this reference in 2006, and the balance between the complications does not show its weight: everything coexists without any visible compromise on the dial.
