Frequently asked questions

What is the exact lug width of the Bulgari B.Zero1 102319?

The lug width of the Bulgari B.Zero1 102319 is precisely 20 millimetres. This measurement is essential for selecting a compatible strap and ensuring perfect fit in the lug holes without gaps or misalignment.

Which strap is most suitable for the Bulgari B.Zero1 102319?

For the B.Zero1 102319, an alligator leather strap is the most sophisticated choice, as its natural grain creates an interesting dialogue with the tubular geometry of the case. Calf leather with vegetable tanning is equally excellent for a patina that develops over time, whilst cotton NATO straps offer contemporary versatility.

How do you change the strap on a Bulgari B.Zero1 102319?

The B.Zero1 102319 strap is changed by removing the retaining pins (or spring bars) that connect the strap to the case through the lugs. Simply use a dedicated tool to extract them gently, then position the new strap correctly before reinserting the pins.

Can I use an aftermarket strap on the Bulgari B.Zero1 102319?

Yes, absolutely. Any strap with a 20-millimetre lug width is compatible with the B.Zero1 102319. Milano Straps offers a comprehensive range of artisanal straps in various materials (alligator, calf, NATO) specifically sized for this measurement, all ready for dispatch.

How long does a leather strap last on a Bulgari B.Zero1 102319?

Strap longevity depends on the tanning type and usage patterns. A calf leather strap with vegetable tanning typically lasts 2-4 years with regular wear, whilst alligator can exceed 5 years. An 18-month warranty is standard, as offered by the Casati Milano atelier for bespoke straps.
