Strap for Master Collection Date 34 Stainless Steel - Diamond / Silver

The lug width of the Longines Master Collection L2.357.0.70.2 is precisely 18mm. This measurement is specific to the 34mm dress watches of the manufacture and is determined by the distance between the inner shoulders of the integrated lugs. Any compatible strap must fit perfectly to this dimension without lateral play.

For the Master Collection L2.357.0.70.2, the finest strap options are alligator or shell cordovan: both maintain the dresswear aesthetic of the case and develop patina over time. Alligator offers natural grain and visible ageing; shell cordovan guarantees superior durability and moisture resistance. For formal evening contexts, smooth black calf leather represents the minimalist alternative. Your choice depends on primary use environment.

The Longines Master Collection L2.357.0.70.2 features integrated non-standard lugs. To change the strap, you must use a spring bar remover tool to extract the spring bars from the case lugs. Proceed with extreme caution to avoid scratching the satin-finished steel case. For precision work, it is advisable to consult a specialised workshop or Casati Milano atelier for risk-free replacement.

Yes, any artisanal strap with an 18mm lug width is compatible with the Longines Master Collection L2.357.0.70.2. High-quality aftermarket straps (alligator, shell cordovan, fine calf leather) often offer superior finish and longevity compared to the original strap, with customisation options (initials, custom stitching thread). Milanostraps supplies personalised 18mm straps ready for dispatch.

Leather strap durability depends on material, tanning method and frequency of use. Smooth alligator with vegetable tanning lasts 3-5 years with moderate daily wear; shell cordovan reaches 5-7 years due to its natural hardness; standard calf leather averages 2-3 years. A dresswear strap worn 2-3 times weekly for formal occasions can last 7-10 years. Maintenance (moisture protection, drying after exposure, annual conditioning) significantly extends useful life.
