Formula 1 CAZ101B.FT8028— lug 20mm

The CAZ101B.FT8028 features a lug width of 20mm, determined by the case width and the geometry of the attachment lugs. This dimension is specific to the model and ensures perfect visual proportion across the 43mm case diameter.

For this sports chronograph we recommend alligator in brown with medium grain finish for elegance, black calf in vegetable tanning for patina development, or a ballistic NATO for a more motorsport-oriented and assertive approach. The choice depends on your usage context and personal colour preferences.

Strap replacement involves removing the springbars that connect the old strap to the case lugs. Use a proper strap change tool to avoid scratching the case. The new 20mm strap is inserted by aligning the lug holes with the springbars, ensuring correct bilateral engagement.

Yes, any aftermarket strap with a 20mm lug width is compatible. We recommend verifying the quality of the lugs (leather or rubber) and the buckle to ensure comfort and security. Milano Straps 20mm straps are tested for compatibility and crafted from premium materials.

A quality leather strap under moderate daily use typically lasts 2–3 years before replacement is needed. With careful maintenance (drying after humidity exposure, protection from direct heat) it can reach 4 years. Vegetable-tanned leather ages more aesthetically than synthetic alternatives.
