Strap for Lyre 35 Automatic Yellow

The lug width (ansa) of the Longines Lyre L4.760.2.12.8 is 18mm. This width is specific to the model and was chosen during the design phase to maintain the harmonious proportions of the 35mm case. The lug depth (vertical space between the pins) is approximately 2.5–2.8mm, a crucial measurement to ensure the strap sits flush against the case without gaps or strain.

Polished alligator in dark tones—black, deep brown, or cognac—is the quintessential choice, as it respects the minimalist language of the case. For those seeking daily versatility, vegetable-tanned calf develops a natural patina over time and offers superior comfort. Shell cordovan is ideal for those who appreciate evolved materials: its density and rich colour create refined contrast with the satinised steel case. For a sportive approach, rubber or NATO straps maintain the contained proportions without compromising practicality.

Remove the strap using a spring bar tool. Position the tool's tip in the small hole on the lug pin, apply gentle pressure to retract it, and slide the pin out from the case. Repeat on the opposite side. When installing the new strap, ensure the pins are aligned and the strap is centred relative to the case. Bespoke straps from makers like Casati Milano include personalised instructions or WhatsApp support to guarantee correct installation.

Yes, the Longines Lyre L4.760.2.12.8 is fully compatible with quality aftermarket 18mm straps. Verify not only the width (18mm) but also the lug depth, which must match the case's 2.5–2.8mm specification. Milanostraps curates a comprehensive collection of 18mm straps in various materials—alligator, cordovan, vegetable-tanned calf—all tested for compatibility. Customisation is available: bespoke sizing, embroidered initials, choice of stitching thread, and buckle options.

Longevity depends on material quality, daily use, and maintenance practices. A quality alligator or shell cordovan strap, with regular wear, maintains structural integrity for 5–8 years. Vegetable-tanned calf, more vulnerable to moisture, demands greater care but may last 4–6 years. Bespoke straps from Casati Milano include an 18-month warranty and care instructions. Lifespan increases significantly if the strap avoids prolonged humidity, direct perspiration, or excessive heat. Preventive replacement is recommended when minor structural softening appears at the edges or base, before sudden failure occurs.
