Strap for Prestige Gold 23

The lug width of the Longines L4.223.7.88.6 is precisely 16mm. This measurement represents the internal distance between the case lugs at the point where they connect to the strap pins. It is essential to verify this measurement with a digital calliper before purchasing an aftermarket strap, as the pins are not universal and an incompatible lug width would create mechanical compatibility issues.

For the 23mm Longines in yellow gold, we recommend straps in dark brown alligator, black shell cordovan, or grey pearl calf leather. Alligator amplifies the classical authority of the case, cordovan guarantees maximum durability and natural ageing patina, whilst calf offers contemporary elegance. Your choice depends on the dial: if silvered, favour brown or cognac tones; if champagne or red, opt for burgundy or formal black.

To change the strap without damaging the case, use a spring bar tool to release the pins connecting the original strap. Position the tool's tip into the small release hole on one side of the pin, applying gentle outward pressure until the pin clicks free. Repeat on the opposite side. Then insert the new strap by threading the pins through the case lugs, ensuring they click completely into position.

Yes, aftermarket 16mm straps are fully compatible with the Longines L4.223.7.88.6, provided they are crafted by artisans respecting manufacturing tolerances. MilanoStraps offers 16mm straps personalised in leather type, length, stitching thread and initials. The Casati Milano atelier creates bespoke straps with direct consultation, providing an 18-month warranty.

Lifespan varies according to material and usage intensity. A calf strap lasts 2-3 years with daily wear and regular maintenance; alligator extends this to 4-5 years; shell cordovan, with superior equine leather density, guarantees 8-10 years or more. Patina and wear marks represent natural beauty, not deterioration. To extend useful life, we recommend alternating straps and protecting against excessive moisture and direct sunlight.
