Strap for Presence 25.5 Automatic PVD Gold / White - Mixed

The lug width (ansa measurement) of the Longines Presence L4.321.2.15.2 is 13mm. This dimension is specific to feminine wrists and requires a proportionately-sized strap to maintain the watch's aesthetic balance. Verify by measuring the distance between the lug holes with a digital calliper, positioning it perpendicular to the case plane.

Alligator leather is optimal: its regular pattern and smooth texture emphasise the minimalist design language. Vegetable-tanned calf offers versatility and develops patina over time. For daily use, a densely-woven cotton NATO strap maintains balanced proportions. FKM rubber suits informal contexts without sacrificing construction quality.

Position the watch on a soft cushion with the case facing downward. Using a spring bar tool, press the small spring-loaded button beneath the lug from the opposite side, lifting the spring bar end. Extract the spring bar and remove the strap. Align the new strap's holes with the lugs and reposition the spring bar by pressing until you hear a click. Test that the strap is securely fastened before wearing.

Yes, provided the lug width is exactly 13mm. High-quality artisanal straps are compatible and often enhance aesthetics and comfort compared to original straps. Choose materials that respect Swiss constructive rigour: alligator, vegetable-tanned calf, or high-density woven NATO are conservative and durable choices.

A high-quality leather strap (alligator or vegetable-tanned calf) lasts between 3 and 5 years in daily use, depending on UV exposure and humidity. Alligator tends to last longer due to superior material density. Vegetable-tanned leather develops aesthetic patina over time, extending visual appreciation. To maximise longevity, minimise exposure to prolonged moisture and salt water.
