Strap for Lyre Quartz 32 Stainless Steel / Silver / Strap

The lug width of the Longines Lyre L4.359.4.72.2 is 16 millimetres. This specific measurement was selected by the manufacturer to maintain proper proportions with the 32-millimetre case diameter. It is essential to verify that any strap purchased matches this dimension precisely, as even minor variations can prevent correct insertion into the lugs.

For this model, an authentic alligator strap in black or cognac brown represents the most appropriate choice. Alternatively, a high-quality calf leather with vegetable tanning offers versatility and a natural patina that develops with time. Shell cordovan straps are discouraged as their thickness alters the proportions of the case. Avoid straps in bright colours, which would conflict with the restrained aesthetic of the Lyre.

To change the strap, remove the lugs from the case using a specialised tool or spring bar removal device. Position yourself in a well-lit, flat workspace, then gently extract the lug by pushing downward with the removal tool. Once extracted, the strap disconnects easily. To insert the new 16-millimetre strap, align the lug with the seats and press until you hear or feel a click. If uncertain, consult a professional watchmaker.

Milanostraps.it provides a dedicated selection of 16mm-compatible straps, crafted from materials such as alligator, vegetable-tanned calf, and others, all customisable in size, colour and stitching.

The lifespan of a leather strap varies depending on material quality, frequency of use and care applied. A high-quality alligator or vegetable-tanned calf strap has an average lifespan of 4–6 years with daily wear, extendable to 7–8 years with proper maintenance: avoid excessive moisture, protect from direct heat sources and periodically apply a protective balm. Lower-quality straps may deteriorate prematurely. Milanostraps offers an 18-month guarantee on Casati Milano straps, with the option for updates and replacements.
