The Heritage

The Apple Watch was introduced in 2015 as the first smartwatch from the California-based manufacturer. The device is equipped with the proprietary Apple Watch calibre with chronograph, perpetual calendar, moon phases and alarm functions. The MJ472LL reference integrates physical activity tracking sensors and wireless connectivity.
Made to Measure

The strap for this watch is made to measure

On the Apple Watch the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

Can a standard strap be fitted to the Apple Watch MJ472LL?

No, a strap with straight bars does not fit the integrated attachment system of the MJ472LL case. The solution is a bespoke strap built directly onto the watch, handcrafted by <a href="/pages/casati-booking">Casati Milano</a> during a private atelier appointment.

How does the bespoke strap service work for this model?

The craftsman examines your watch in the atelier, precisely measures every detail of the proprietary attachment, discusses leather selection and finishes with you, then builds the strap directly onto the case. Every millimetre is calibrated for perfect fit to the case geometry.

Which leather suits the character of the Apple Watch MJ472LL best?

The minimalist Californian design of the MJ472LL calls for leathers with fine, uniform grain such as box calf or cordovan in neutral tones (black, dark brown, slate grey). Some prefer vegetable-tanned leathers with more pronounced texture to create intentional contrast between the case's high-tech aesthetic and the leather's artisanal quality.

How long does a well-made leather strap last?

An artisanal strap crafted from quality leathers and conscious stitching lasts 3 to 5 years of daily wear, sometimes longer. Leather develops patina and character over time; longevity depends on use, maintenance, and the initial quality of the raw material.

Why does the 2015 Apple Watch MJ472LL deserve a bespoke strap?

The MJ472LL represents the foundation of the smartwatch revolution: rigorous design, noble materials (ceramic and stainless steel), complex movement with astronomical functions. A bespoke strap makes it wearable on your wrist and reconciles it with artisanal tradition, transforming it into a consciously crafted object.
