The Record L2.821.5.57.2 (aka: L28215572), seen from the bench

The Longines Record L2.821.5.57.2 (ref. L28215572) represents the contemporary evolution of a collection established in 1918, symbolizing Swiss precision and elegant understatement. This 40mm stainless steel and pink gold case model features the Longines caliber L888.4 movement with chronometer-certified performance. The 20mm lug width integrates perfectly with the case proportions, while the scratch-resistant sapphire crystal, 30-meter water resistance, and screw-down crown provide robustness without compromising refinement.

Frequently asked questions

What is the exact lug width of the Longines Record L2.821.5.57.2?

The lug width of the Longines Record L2.821.5.57.2 is 20 millimetres. This measurement is taken internally, from the point where the strap attaches on one lug to the opposite side. The 20mm width is proportionally designed to suit the 40mm case diameter, ensuring perfect visual balance and mechanical compatibility with any 20mm strap.

Which strap material is best suited for the Longines Record L2.821.5.57.2?

Alligator leather with vegetable tanning represents the most sophisticated choice for the Record, as its natural texture elegantly complements the steel and rose gold bicolour. Alternatively, vegetable-tanned calf leather offers versatility and durability, developing a noble patina over time. Shell cordovan is ideal for those who appreciate the conscious evolution of leather, whilst rubber or NATO fabric straps suit more casual wear.

How do I change the strap on the Longines Record L2.821.5.57.2?

Strap replacement on the Longines Record is accomplished by removing the spring bars (metal pins) that secure the strap to the case lugs. This operation requires a proper spring bar tool to prevent scratching the case. If you lack the tool or prefer professional assistance, Casati Milano offers replacement services with specialist personnel, ensuring maximum precision and case protection.

Is the Longines Record L2.821.5.57.2 compatible with quality aftermarket straps?

Yes, the Longines Record L2.821.5.57.2 is fully compatible with quality artisanal 20mm straps. The key requirement is accurate lug width measurement (20mm) and appropriately sized spring bars. milanostraps.it offers a curated selection of compatible straps, crafted from premium leathers including alligator, calf, and cordovan, guaranteeing perfect fit and construction quality equivalent to leading brands.

How long does a natural leather strap with vegetable tanning last on a watch like the Longines Record?

A natural leather strap with vegetable tanning, properly used and receiving minimal maintenance (occasional cleaning, protection from excessive humidity), typically lasts 3–5 years with regular wear. Longevity depends on frequency of use, climatic conditions, and whether the strap is rotated across multiple watches. Casati Milano provides an 18-month warranty on its straps and recommends periodic rotation to extend service life.
