Strap for Master Collection 34 Stainless Steel - Pink Gold / Silver

The lug width of the Longines Master Collection L2.357.5.70.2 measures 18mm. This dimension is specific to the model and reflects the balanced proportion between the case diameter (34mm) and the strap. To measure correctly, position a calliper perpendicularly between the two metal lugs that accommodate the strap, excluding any protective rubber gaskets.

For the Master Collection L2.357.5.70.2, high-quality aesthetic materials are recommended: black alligator for formal continuity, brown shell cordovan for elegance with character, beige vegetable-tanned calf for contemporary minimalism, or NATO blue/green for everyday versatility. The choice depends on intended use and wrist tone: premium leathers for formal occasions, NATO for daily versatility.

The strap on the L2.357.5.70.2 is changed via spring bars located at the ansa extremities. Use a spring bar remover or thin flat tool to compress the spring and release the bar from the lug. Repeat for the opposite end, then insert the new strap while maintaining the spring bar in horizontal position and sliding the bar back into the seats. Symmetrical and reversible operation.

All straps with an 18mm lug width are compatible with the L2.357.5.70.2, whether produced by major manufacturers or specialist artisans. On milanostraps.it, a complete selection of 18mm straps is available in alligator, cordovan, calf, NATO and vulcanized rubber, with customization options (dimensions, initials, thread colour).

The lifespan of a leather strap depends on usage, material and maintenance. High-quality alligator and shell cordovan maintain structural integrity for 5-8 years with moderate use (3-4 days weekly). Vegetable-tanned calf requires more frequent maintenance but reaches 4-6 years. Standard warranty is 18 months. Factors that reduce lifespan: constant sun exposure, humidity, perspiration, lack of nocturnal ventilation.
