Strap for Master Collection Date 38.5 Two Tone Stick

The lug width of the Longines Master Collection L2.628.5.12.7 is 20 millimetres. This is the internal distance between the attachment pins that hold the strap onto the case. Verifying this measurement is essential before purchasing a compatible strap, as even one millimetre of difference would compromise the correct fit.

For the Longines L2.628.5.12.7, straps in alligator, calf, shell cordovan, or rubber are recommended, all available in 20mm lug width. Black or brown alligator conveys formal elegance; vegetable-tanned calf offers softness and natural patina; shell cordovan suits those seeking chromatic depth. The choice depends on intended use: dress watch contexts demand noble leather, whilst technical rubber is advisable for humid climates.

To change the strap, you must remove the pin passing through the lugs using a dedicated tool (spring bar tool) or consult a watchmaker. The pins on the Longines L2.628.5.12.7 are standard diameter and extract easily once the correct lever point is identified. It is advisable to place a soft cloth beneath the wrist during the operation to avoid scratching the case.

Yes, third-party 20mm straps are fully compatible with the Longines L2.628.5.12.7. Quality depends on the supplier: alligator or calf straps with vegetable tanning from specialised artisans guarantee superior durability and patina compared to industrial straps. Lug width compatibility is the sole essential technical parameter; everything else is qualitative and aesthetic choice.

A noble leather strap (alligator, calf, cordovan) with regular use typically lasts 3–5 years before replacement is needed. Lifespan depends on frequency of wear, moisture exposure, and maintenance: avoiding prolonged water contact and allowing natural drying extend life. Vegetable-tanned straps develop patina that improves over time, but the fibrous structure gradually wears. Specialised artisans offer regeneration services to extend useful life.
