Strap for Master Collection Date 38.5 Two Tone Roman

The lug width of the Longines Master Collection L2.628.5.11.7 is 20 mm. This is the distance between the inner shoulders of the lugs where the strap is inserted. This dimension is critical for compatibility: only 20 mm straps will fit correctly without any structural modification.

Alligator represents the formal choice par excellence, with a refined texture that complements the case's sobriety. For daily versatility, vegetable-tanned calf offers a patina that evolves over time. FKM rubber with gold deployante is ideal for intensive use, whilst NATO in certified textile fabric transforms the model into a more sporting instrument.

Strap replacement requires a spring bar tool to compress the internal springs at the lugs. Position the tool at the base of the lug, gently compress the spring, remove the original strap, then insert the new 20 mm strap by aligning the ends to the lug shoulders. If uncertain, Casati Milano atelier provides this service with warranty and personalised consultation.

Yes, any 20 mm strap is compatible with your Longines Master Collection L2.628.5.11.7, provided it is manufactured from certified watchmaking materials (full-grain leather, FKM rubber, certified textile canvas). MilanoStraps offers handcrafted customisable straps that guarantee construction excellence and aesthetic coherence with your timepiece's value.

A high-quality watchmaking leather strap (alligator, calf, shell cordovan) lasts an average of 3–5 years with moderate daily use. Alligator tends to resist wear better due to its scale structure. Vegetable-tanned leather develops a natural protective patina that extends longevity. Casati Milano atelier guarantees 18 months and offers restoration services for aged leather straps, keeping them wearable.
