Strap for Avant-Garde Date Black / Strap

The lug width of the Eterna Contemporary 2945.41.50.1338 is 20mm. This measurement must be taken between the lugs (spring bars) that attach the strap to the case, not across the external surface. Verifying this dimension is essential before purchasing any aftermarket strap.

For the Contemporary 2945.41.50.1338, an alligator strap with vegetable tanning represents the most elegant choice, emphasizing the subtlety of the satin-finished case. Vegetable-tanned calf leather offers chromatic versatility, whilst a cotton NATO or satin FKM rubber maintains the contemporary sporting character of the timepiece. Your choice depends on intended use and wearing context.

Remove the original strap using a spring bar remover tool. Position the watch on a soft surface, gently compress the lateral spring bar to disengage the lugs, then insert the new 20mm strap. Verify that both spring bars are securely fastened to the lugs before wearing. If you are inexperienced, consult a professional watchmaker.

Yes, any strap with a 20mm lug width is compatible with the integrated lugs of the Contemporary 2945.41.50.1338. The case architecture remains unaltered. By selecting aftermarket straps, you can diversify the aesthetic whilst preserving the case geometry and construction balance of the timepiece.

A quality leather strap with vegetable tanning, worn daily, typically lasts between 3 and 5 years. Longevity depends on humidity exposure, frequency of use, and maintenance (avoid prolonged immersion; clean periodically). A vegetable-tanned strap develops natural patina that increases aesthetic value over time. Contact Milano Straps for timely replacements.
