Strap for Avant-Garde Date Two Tone / Silver / Bracelet

The Eterna Contemporary 2945.53.61.1716 is equipped with a lug width of 20 millimetres. This measurement refers to the internal distance between the spring bars and is critical for determining strap compatibility. It is advisable to verify with precision using a digital calliper, measuring perpendicular to the centre of the lug.

For this timepiece, we recommend alligator in vegetable tannage with a deployante buckle: the elegance of the natural texture dialogues perfectly with the Swiss architecture of the case. Alternatively, charcoal calf for a softer hand, or grey NATO for casual contexts. The choice depends on prevailing use and your specific dial.

Position the watch on a stable surface, lugs facing upward. Use a dedicated tool (spring bar tool) to compress the spring bar whilst maintaining pressure as you extract the old strap. Insert the new strap by applying the same pressure on the spring bar until the safety click. Avoid hammers or crude tools that may damage the case.

Yes, all artisanal straps with 20mm lugs are compatible. We recommend verifying that the total width of the strap (including the shoulders) does not exceed the case geometry. Milano Straps curates collections specifically for this diameter and case proportion.

An alligator or vegetable-tanned calf strap, used reasonably (4–5 days weekly), has a lifespan of 5–8 years before elasticity begins to compromise functionality. The evolving patina is part of the aesthetic value. Maintenance (occasional conditioning, protection from salt water) significantly extends functional duration and preserves appearance.
