FAQ

What is the lug width of the Eterna Heritage 2960.69.11.1272?

The lug width of the 2960.69.11.1272 is 20mm. This measurement is taken between the two lugs (metal springs) protruding from the case. You can verify this using a digital calliper positioned perpendicularly between the two attachment points. A 20mm lug width is considered medium-sized, ideal for wrists between 16cm and 19cm, and offers compatibility with a broad range of aftermarket straps.

Which strap is recommended for the Eterna Heritage 2960.69.11.1272?

For the Heritage 2960.69.11.1272, alligator straps with vegetable tanning are recommended for formal occasions, brown tobacco calf leather for elegant everyday wear, or NATO straps in neutral tones for a sporty approach. Natural patina alligator in Havana tone emphasises the contrast with rose gold, whilst shell cordovan offers dense texture and substantial shoulder. Your choice depends on intended use: formal, everyday or sporty.

How do I change the strap on the Eterna Heritage 2960.69.11.1272?

To change the strap on the 2960.69.11.1272, position the watch on a soft surface. Locate the spring bars (small metal rods) that connect the strap to the case lugs. Use a spring bar tool to compress the internal spring of the pin, then extract the strap. Repeat on the other side. Insert the new strap by positioning the spring bars in their grooves and compressing the pin until it clicks into place.

Is the 2960.69.11.1272 compatible with aftermarket 20mm straps?

Yes, the Eterna Heritage 2960.69.11.1272 is fully compatible with any aftermarket strap featuring a 20mm lug width. This standard width guarantees extensive material options: leather, NATO, rubber, mesh and elasticated designs. Milano Straps offers a specialised catalogue of customisable 20mm straps for this model, with finishes suited to rose gold.

What is the lifespan of a leather strap on the Eterna Heritage 2960.69.11.1272?

The lifespan of a leather strap depends on the material type and usage frequency. A vegetable-tanned leather strap, worn daily, typically lasts 3-5 years before replacement is warranted. Shell cordovan, being more durable, can last 5-7 years. Determinant factors include sun exposure, humidity and frequency of wear. Proper periodic maintenance—including gentle cleaning with damp cloth and conditioning with specialist creams—significantly extends strap longevity.
