Strap for Da Vinci Tourbillon Quattro Stagioni / German / Bracelet

The lug width of the IWC Da Vinci IW9267-05 is 19 millimetres. This measurement is taken between the horizontal pins that anchor the strap to the case. It is the historical standard for Da Vinci models, chosen by IWC to maintain harmonious proportions on a 39mm case.

Alligator in dark brown or black represents the most suitable choice: the directional grain creates dialogue with the warmth of the gold, evolving naturally over time. Alternatively, calf leather with vegetable tanning in honey or cognac tones offers superior aesthetic maturation and tactile comfort. Avoid synthetic or faux-leather straps, which compromise the watch's authority.

The strap is changed by removing the horizontal pins (typically using a dedicated tool supplied by IWC or by a qualified watchmaker). Insert the first pin into the upper seat, slide out the old strap, then thread the new strap and secure the second pin. This delicate operation is best performed by a qualified craftsman to avoid scratches on the yellow gold case.

Available online from specialists in fine leathers: alligator, shell cordovan, vented calf, vegetable-tanned leather. Atelier Casati Milano also manufactures bespoke straps with personalised leather selection and 18-month guarantee.

Vegetable-tanned calf may last 2-4 years before replacement is warranted. Lifespan depends on sun exposure, relative humidity, and strap rotation frequency.
