Strap for Kalpa Donna

The Kalpa's lug attachment is an integral part of the tonneau case geometry, so a standard strap manufactured to conventional measurements cannot respect the architectural integrity of the design. The solution is to construct a bespoke strap directly on the case by analysing the precise lug dimensions in the workshop. <a href="/pages/casati-booking">Casati Milano</a> undertakes this custom construction, exclusively by appointment.

The master craftsman surveys the exact geometric dimensions of your Kalpa PFC1600020701B00002 lugs, analyses the tonneau case shape and lug position. He then selects the leather and constructs a strap dimensioned so that the passants sit without generating tension on the case and the lug becomes a natural extension of the design. The strap is therefore built exclusively for this watch.

Vegetable-tanned calf leather with fine grain amplifies the formal sobriety of the tonneau case and dialogues perfectly with the materiality of the steel. Natural vegetable leathers, with their evolving patina, create a temporal narrative parallel to the watch itself. What matters is that the texture remains subordinate to case architecture, without competing visually with the tonneau design.

A bespoke strap realised with selected leather and artisanal stitching develops a useful life of 8–12 years if subjected to ordinary maintenance: periodic cleaning, conditioning with specific creams, and seasonal rest. The leather, like steel, evolves over time, accumulating patina and character. Durability also depends on daily use and climatic conditions, but construction quality ensures the strap ages with nobility.

The PF600 calibre was conceived by Parmigiani Fleurier to mirror the same philosophy of aesthetic sobriety as the tonneau case: hours and minutes without superfluous ornamentation, with a constructive vision that exalts pure function. It is a movement that narrates Parmigiani Fleurier's independent identity, where every internal element serves a precise purpose, without compromise to decorativism.
