Longines
Master Collection L2.357.4.08.6— lug 18mm

The lug width of the Longines Master Collection L2.357.4.08.6 is 18 mm. This standard width accommodates any 18 mm strap available on the market, from calf leather to alligator, rubber, and specialty fabrics.

For this dresswear model, we recommend alligator or vegetable-tanned calf in dark brown, cognac, or black tones. If you prefer a sportier approach, rubber or leather NATO straps maintain elegant functionality. Your choice depends on use: formal wear = alligator, daily wear = calf, sports = rubber.

Remove the two spring bars positioned on the inner side of each lug using a spring bar removal tool or flathead instrument. Extract the old strap and insert the new one, ensuring both springs click firmly into the lug holes. Professional assistance is recommended if you prefer to avoid DIY installation.

Yes, any strap with an 18 mm lug width is compatible with the L2.357.4.08.6. Milanostraps offers handcrafted 18 mm straps customisable in leather type, colour, monogram initials, and stitching, guaranteeing quality superior to standard replacement straps.

A quality leather strap with vegetable tanning lasts approximately 3–5 years with regular daily wear. Alligator and shell cordovan offer greater durability (5–8 years). The patina that develops over time is a desirable characteristic. Storing the strap away from moisture and excessive heat preserves longevity.
