Strap for BC3 Advanced Day Date Stainless Steel / Silver / Rubber

The lug width of this model is precisely 22mm. To verify, measure the distance between the case lugs using a digital calliper. This width accommodates substantial strap thickness (1.4–1.6mm) whilst maintaining wrist movement fluidity.

We recommend Tuscan leather with vegetable tanning in dark brown vintage tonality: it offers natural elasticity, evolving patina over time, and atmospheric resistance superior to synthetic tannages. Alternatively, NATO straps in olive green ballistic canvas enhance the avionic identity of the instrument.

Remove the strap by gently pressing the lateral release pins downward until the ends protrude from the case. Insert the new pins into the replacement strap, align with the case lugs, and press until the locking click engages. Verify the pins are fully inserted and the strap does not move laterally.

Yes, the BC3 is fully compatible with any quality 22mm strap. Milano Straps offers an extensive selection of artisanal leather, NATO, and rubber straps, all tested for mechanical and aesthetic compatibility with the 42mm stainless steel case of this model.

A high-quality leather strap (e.g. Tuscan vegetable-tanned) maintains structural integrity for 4–6 years of daily use. Longevity depends on ambient humidity, cleaning frequency, and conditioning care. Regular maintenance with natural oils significantly extends useful life.
