Strap for GA-100C-1A3 Green Hands

No, the attachment system is proprietary Casio and integral to the case geometry. A standard strap with straight spring bars is incompatible. However, a strap does exist and is possible: it must be constructed bespoke directly on the watch at <a href="/pages/casati-booking">Casati Milano</a>, measuring the exact coordinates of the attachments and crafting an accessory that integrates flawlessly into the case structure.

The artisan at Casati Milano examines your watch in the atelier, measures the precise distance between the proprietary attachments, evaluates inclination angles and case proportions. Based on this foundation, they construct the strap by cutting the leather, assembling the layers and stitching every element directly onto the GA-100C-1A3 geometry. It is realised exclusively by appointment, with every parameter personalised to your watch.

Leathers with pronounced grain engage in stylistic contrast with the rigid geometry of the resin case. A fine alligator grain or aged vegetable-tanned calf create lines of force that echo the case's channelling. Even a satin leather, deliberately burnished and minimalist, functions as tonal shading, leaving protagonist status to the watch's architectural design.

A strap constructed from quality leather and artisanal stitching endures years with mindful maintenance. Natural leather ages and patinas, acquiring character in time. Casati Milano employs materials that improve aesthetically with wear, transforming the strap into a living object that evolves alongside the watch.

Launched in 2010, the model redefined tool watch aesthetics by rejecting digital minimalism and embracing instead oversized architectural geometries. The 55mm oversize case, the multi-layered design and the 5081 calibre with perpetual calendar and chronograph established it as a reference point for those seeking aesthetic robustness without compromise. It is a constructivist object that ages well and deserves completion with a strap reflecting this stature.
