Strap for Master Collection Date 34 Stainless Steel / Beige - Diamond / Bracelet

The lug width of the L2.357.4.07.6 is 18 millimetres. This measurement is specified by Longines to maintain correct optical proportions relative to the 34-millimetre case diameter. It is not possible to fit straps of different dimensions: the case accepts exclusively 18-millimetre lug widths.

The best strap depends on intended use. For formal contexts, a dark brown or black alligator offers discreet elegance. For conscious daily wear, a vegetable-tanned calf in cognac brown tones allows progressive patina development. Shell cordovan is ideal for those seeking rarity and tactile compactness. For versatility, a NATO in neutral colours guarantees rapid changing without aesthetic compromise.

The strap is removed by extracting the lateral pins using a dedicated tool (strap remover) inserted beneath the lug and gently pressed outward. The pins slide in channels and extract from the case's internal side. The new strap is fitted by aligning the lug holes with the pins and inserting them until they lock. The operation requires care to avoid scratching the case.

Yes, any strap with an 18-millimetre lug width is compatible with the L2.357.4.07.6. Quality aftermarket straps allow customisation in materials (alligator, calf, shell cordovan), colours and finishes. Ensure the strap is precisely dimensioned at 18 millimetres to avoid play or excessive pressure on the lugs.

A quality leather strap has an average lifespan of 3–5 years with regular daily use. Factors affecting longevity: leather quality (alligator and shell cordovan last longer than standard calf), tanning method (vegetable tanning maintains flexibility longer than chemical tanning), exposure to humidity and perspiration, maintenance (periodic cleaning, drying after water contact). A vegetable-tanned calf strap develops patina and becomes softer over time without losing functionality.
