Strap for Da Vinci SL Chronograph MecaQuartz Stainless Steel Brushed / Black / Bracelet

The lug width of the IWC Da Vinci IW3728-05 is 19 millimetres. This measurement refers to the distance between the two metal lugs attached to the case. To verify this specification, measure the space between the lugs on your case: 19 millimetres is the exact width required for proper fitment with any compatible strap designed for this model.

We recommend alligator leather with fine grain or vegetable-tanned calf leather for the Da Vinci IW3728-05. Alligator enhances the classical, geometric character of the squared case, whilst vegetable-tanned calf develops a natural patina over time, creating an elegant dialogue with the steel's grey tone. Both materials maintain aesthetic coherence with the visible calibre through the exhibition caseback and the manual-winding movement.

Strap replacement on the IW3728-05 is performed by releasing the spring bars that secure the lugs to the case. Use a dedicated spring bar tool: position the tip in the bar's groove, apply gentle pressure to release the old strap, then insert the new strap with 19mm lug width. Avoid excessive force to prevent damage to the case lugs. If you lack experience, contact our Casati Milano atelier for professional strap replacement with warranty coverage.

Yes, any strap with a 19mm lug width is compatible with the IW3728-05, provided it meets standard manufacturing tolerances. Milano Straps artisanal straps are crafted with millimetre precision and guarantee perfect fitment. Choose from premium materials—alligator, calf, or shell cordovan—to preserve the chronograph's elegance and your investment's longevity.

A premium leather strap (alligator or vegetable-tanned calf) typically lasts 3 to 7 years, depending on intensity of use and maintenance routine. Frequent exposure to humidity, perspiration, and sunlight reduces lifespan. Calf leather ages gracefully: the patina deepens and gains character whilst retaining structural integrity. Our artisanal straps carry an 18-month defect guarantee; consistent care (gentle cleaning, periodic conditioning) significantly extends useful life.
