Strap for BC3 Sportsman Day Date Stainless Steel / Black / Bracelet

The lug width is exactly 22 millimetres. This dimension is calibrated to the proportion of the 42mm case and is specific to this model. To verify compatibility, measure the distance between the inside of the two metal lugs: it must be precisely 22mm.

The choice depends on use: genuine alligator or grain leather offers elegance without sacrificing robustness; a NATO in regenerated yarn ensures versatility and easy cleaning, perfect for aviation context; rubber remains the ideal solution for humid environments or extreme temperature variations.

Use a dedicated tool to gently push the springbars inward towards the case, freeing one end of the lug. Completely remove the strap and insert the new one, aligning the 22mm width into the slots. Ensure that the springbars click firmly into position.

Yes, any 22mm strap is compatible with this model. However, verify that the thickness of the leather or fabric does not exceed 3-4mm to ensure optimal grip in the lugs and uniform wear over time.

A quality leather strap (vegetable-tanned alligator or grain leather) typically lasts 18-36 months with daily wear, depending on humidity exposure, sweat pH and maintenance. Vegetable tanning develops patina that increases beauty; synthetic leather degrades faster but requires less care.
