Zenith
Elite 18.2290.679/18.C498— lug 20mm

The Zenith Elite ref. 18.2290.679/18.C498 is equipped with a lug width of 20mm. This measurement represents the net distance between the two lateral attachment points on the case and is essential for selecting compatible straps. To verify it, position the watch with the caseback facing upward and measure between the inner points of the two lugs perpendicular to the case.

For the Zenith Elite 18.2290.679/18.C498 in rose gold, the most aesthetically appropriate strap is dark brown or cordovan alligator, which maintains formal coherence with the dress watch character of the timepiece. Alternatively, vegetable-tanned calf leather in cognac tones or bordeaux shell cordovan naturally dialogue with the warm hue of rose gold, developing distinctive patina over time.

Strap replacement requires a specialised tool (spring bar removal tool). Position the watch on a stable surface with the lug facing you, gently insert the tool tip into the spring bar groove to release tension, extract the lug from the case, remove the old strap and insert the new one by reversing the procedure. To avoid risk of scratching the case, you may request the service from Casati Milano, which performs the change with precision guarantee.

Yes, all straps with 20mm lug width are compatible with the Zenith Elite ref. 18.2290.679/18.C498, provided the spring bar is correctly dimensioned (typically 1.5mm diameter). Milano Straps supplies exclusively verified straps for this compatibility, available in artisanal craftsmanship with premium leathers (alligator, vegetable-tanned calf, shell cordovan) and customisable in size, initials and stitching thread.

The lifespan of a leather strap depends on material and wear: alligator or vegetable-tanned calf, worn daily with ordinary care, maintains structural integrity for 3–5 years; shell cordovan, thanks to superior resistance, can extend this interval to 7 years. Frequent exposure to water, moisture and dirt significantly reduces durability. The patina that develops is beneficial and natural; when the strap shows structural failure at the lug, replacement by a professional is advisable.
