Strap for Master Collection Date 47.5

The lug width of the Longines Master Collection L2.689.4.78.6 is 25mm. This dimension is specific to this model and requires compatible straps of the same size. To verify correct measurement, use a digital calliper positioned at the strap attachment seat on the case: the maximum tolerance is ±0.5mm.

Alligator leather with vegetable tanning is the most harmonious choice from an aesthetic standpoint, ensuring patina evolution over time and longevity of 5-7 years of daily wear. Alternatively, shell cordovan offers superior natural density and resistance, whilst anilina calf leather permits an almost limitless colour palette. For a more casual style, NATO fabric straps dialogue interestingly with the stainless steel case.

Strap replacement is performed by removing the lateral attachment pins using a spring bar tool. Position the tool in the seat beneath the case, compress the pin's internal spring slightly and extract. Insert the new strap aligning the pins to the 25mm lugs, ensuring they enter fully. If inexperienced, it is advisable to entrust the operation to an expert.
