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

The lug width (distance between the case lugs) of the Eterna Contemporary 2945.53.66.1716 is 20mm. This measurement is the internal distance between the spring bar attachments on the case. For precise measurement, we recommend using a digital calliper positioned perpendicular to the watch's longitudinal axis. Respecting this measurement exactly is essential to ensure proper strap installation and avoid mechanical play.

The Eterna Contemporary 2945.53.66.1716 pairs ideally with straps made of natural leather using vegetable tanning, particularly alligator or calf leather with fine grain. Alternatively, a cotton NATO strap or an FKM rubber strap preserves the technical vocation of the model. The choice depends on use: leather for formal contexts, rubber for water sports and outdoor activities, NATO for daily versatility.

Changing the strap on your 2945.53.66.1716 is accomplished using a metal spring bar tool positioned beneath the lug spring. Insert the tool into the small lateral slot of the spring, exert gentle inward pressure to disengage the bar, then extract it from the case. Repeat on the other side. When installing the new 20mm strap, ensure the lugs seat perfectly into the case recesses, avoiding misalignment.

The lifespan of a leather strap depends on usage and maintenance. With quality vegetable tanning, the strap should maintain structural integrity for 3–5 years of daily wear. It is advisable to avoid prolonged water immersion, protect against excessive heat sources, and periodically apply natural conditioners to maintain flexibility and patina development. Technical rubber, conversely, offers superior longevity (7–10 years) with minimal maintenance.
