Strap for GA-100-1A2 Black Blue

Not a standard one: the attachment is an integral part of the case design and does not match universal lugs. However, a bespoke strap can be constructed directly on your watch by <a href="/pages/casati-booking">Casati Milano</a>. Measurements are taken in the atelier during your appointment.

The craftsman measures the case proportions, lug width, and attachment angles. The strap is then constructed specifically for your watch, ensuring the material dialogues perfectly with the resin geometry and the aesthetic intention of the piece. Every detail—stitching, buckle, thickness—is designed for that particular case.

Natural-aged full-grain bull leather amplifies the contrast between resin rigidity and leather softness; dark aniline conveys minimalist restraint and emphasises dial clarity; waxed canvas and cordura align with the watch's streetwear origins. Choice depends on use: mountaineering demands vegetable-tanned, moisture-resistant leather; urban wear permits vintage hide with pronounced patina.

A hand-stitched strap in vegetable-tanned leather, with quality thread, ages elegantly and lasts years, developing patina and personality. Longevity depends on maintenance—regular cleaning, protection from stagnant moisture—and material quality. Casati Milano sources proven European hides.

Introduced in the 1990s, the GA-100 crystallised the brand's aesthetic in a massive 55mm form, incorporating perpetual calendar and technologies that make it suitable for both daily wear and extreme environments. It became an icon of contemporary streetwear and sports fashion culture, never compromising its inherent robustness.
