Strap for Master Collection 34 Moonphase Stainless Steel / Silver / Bracelet

The Longines Master Collection L2.409.4.78.6 features an 18-millimetre lug width. This is a standard measurement well-represented in the bespoke watch strap market, ensuring abundant options in materials and finishes without requiring custom solutions.

The choice depends on intended use. For formal occasions, we recommend dark brown alligator or black vegetable-tanned calf leather. For versatility and patina development, burgundy shell cordovan is unbeatable. For daily practicality, structured rubber maintains the model's sober elegance.

The strap is replaced by extracting the spring bars connecting it to the lugs. Using a spring bar tool, remove the bar, extract the old strap, and insert the new one, aligning the holes with the lugs. The operation requires care to avoid scratching the case.

Yes, entirely. The 18mm lug width is a well-established standard. Any strap manufactured to this specification will be compatible. We recommend verifying thickness and total length to ensure comfort and correct aesthetics across different wrist sizes.

Durability depends on material and frequency of use. Vegetable-tanned calf: 3-5 years in regular use. Alligator: 5-8 years. Shell cordovan: 8-10 years due to exceptional resistance. With periodic maintenance and rotation between multiple straps, longevity extends significantly.
