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

The lug width of the Longines Master Collection L2.357.5.70.7 is 18 millimetres. This measurement refers to the space between the two lugs where the strap is attached to the case. It is essential to verify this specification when purchasing an aftermarket strap, as even a 0.5mm difference will compromise the proper fit.

For the 34mm Master Collection L2.357.5.70.7, alligator leather with vegetable tanning is the most coherent choice: the natural grain aligns perfectly with the brushed steel case. Shell cordovan is ideal if you desire a patina that develops over time. Vegetable-tanned calf leather with water-repellent treatment offers durability whilst maintaining elegance. NATO fabric straps are a valid option for more casual and sporty occasions.

To change the strap, you must remove the spring bars connecting the strap to the case. Use a spring bar tool to gently compress the internal mechanism of the bars, thereby releasing the strap from the lugs. Once the old strap is removed, align the new strap with the lug holes and reposition the spring bars. If you are not experienced, consult a professional watchmaker.

Yes, the L2.357.5.70.7 features a standard 18mm lug width, ensuring a wide selection of compatible aftermarket straps. Online, you will find alligator, cordovan, calf, rubber and fabric straps all compatible with this measurement. MilanoStraps offers a complete range of customisable 18mm straps, with options for stitching, colour and initials.

The lifespan of a leather strap depends on frequency of use, sun exposure and tanning method. A quality alligator or cordovan strap, with vegetable tanning, can last 5-8 years of daily wear, developing a desirable patina. Softer vegetable-tanned calf leather tends to wear sooner, typically within 3-5 years. Regular maintenance (gentle cleaning, drying after moisture exposure) significantly extends the strap's lifespan.
