Strap for Lyre Quartz 38.5mm Roman / Bracelet

The lug width of the Longines Lyre L4.859.4.11.6 is 20 mm. This measurement is specific to this model and requires precise measurement of the distance between the inner edges of the case lugs to ensure strap compatibility. A tolerance variance of 0.5 mm in excess or deficit can cause undesirable lateral movement.

Given its classical character and brushed stainless steel case, the Longines Lyre L4.859.4.11.6 pairs ideally with American alligator, shell cordovan, or vegetable-tanned calf leather straps. American alligator represents the purist choice, whilst shell cordovan develops a unique patina over time. Vegetable-tanned calf offers superior longevity and constructive sustainability.

To change the strap on your Longines Lyre, you must remove the spring bars that connect the case lugs to the strap. Use a dedicated spring bar tool to gently press the bar on one side, creating sufficient space to extract the strap. Insert the new strap by aligning the holes with the lugs and release the bar. MilanoStraps provides detailed instructions with every purchase.

The lifespan of a leather strap depends on material type and usage. A shell cordovan strap lasts 3–5 years with daily wear and regular maintenance. Alligator resists for 2–3 years. Vegetable-tanned calf offers superior longevity (4–6 years) due to enhanced aging resistance. MilanoStraps provides an 18-month warranty on all bespoke straps.
