Strap for Master Collection 40 Date Stainless Steel - Pink Gold / Silver / Bracelet

The lug width of the Longines Master Collection L2.793.5.70.7 is 21 millimetres. This measurement defines the distance between the two spring bars that connect the strap to the case. To verify compatibility, use a calliper or ruler and measure the internal space between the lugs: it must be exactly 21mm.

The best strap depends on usage and personal aesthetic preference. For formal occasions, an alligator strap in vegetable tanning—cognac or black—enhances the elegance of the rose gold and steel case. For a sportier approach, a NATO strap in polyamide or cotton-blend fabric offers versatility. For daily wear, smooth calf leather ensures comfort and durability. The ideal choice reflects the predominant context of use.

Strap replacement requires extraction of the spring bars that connect the lugs to the case. Proceed as follows: place the watch on a soft surface; use a spring bar tool or small flat screwdriver; gently press inward on one side of the bar; once loosened, extract the bar from the lug; repeat on the other side. Insert the new strap onto the bars and reinsert the bars into the case lugs. Ensure the bars are fully seated, verifying that the strap does not move laterally.

Yes. The Longines Master Collection L2.793.5.70.7, with 21mm lugs, is compatible with aftermarket straps of identical width produced by specialist craftspeople. MilanoStraps offers a comprehensive selection of 21mm straps in alligator, shell cordovan, calf leather, NATO, and rubber. These straps can be personalised in length, stitching thread, and finishes. Compatibility is guaranteed, as standard Longines spring bars fit perfectly with any strap manufactured to 21mm specifications.

The lifespan of a leather strap depends on the material and intensity of use. An alligator or shell cordovan strap in vegetable tanning lasts an average of 5-10 years with daily wear, thanks to the inherent resilience of the leather and its patina-development capability, which extends its aesthetic appeal. Calf leather, being more delicate, has a lifespan of 3-5 years with intensive use. Rubber or NATO straps last 5-7 years. Storing the watch away from direct sunlight prolongs strap life. The standard warranty offered by MilanoStraps covers 18 months from manufacturing defects.
