Frequently asked questions
What is the lug width of the Longines Présence L4.790.4.12.6?
The lug width of the Longines Présence L4.790.4.12.6 is 30mm. This non-standard measurement requires specifically dimensioned straps and represents a distinctive feature of this model. It is essential to verify the correct measurement before ordering an aftermarket strap.
Which strap material pairs best with the Longines Présence L4.790.4.12.6?
For the Présence, an elegant and versatile timepiece, we recommend lacquered calf leather for formal occasions, or alligator leather for those desiring a more pronounced texture. For daily wear, vegetable-tanned calf leather ensures natural patina development over time. Modern alternatives include FKM rubber straps for water sports activities, whilst maintaining the model's understated aesthetic.
How do you change the strap on a Longines Présence L4.790.4.12.6?
Strap replacement is accomplished by removing the spring bars that connect the case lugs to the strap. Use a dedicated spring bar remover tool to prevent case damage. On models equipped with a deployante, remove the clasp from the old strap first. For those inexperienced with the procedure, we recommend having an authorised watch centre perform the operation to ensure proper assembly and case protection.
Is an aftermarket strap compatible with the Longines Présence L4.790.4.12.6?
Yes, provided it respects the 30mm lug width and the strap width is proportionate to the case dimensions. Artisanal 30mm straps from MilanoStraps are fully compatible and customisable. Always verify that the strap has been measured on the basis of lug width (30mm) rather than case width to avoid ordering errors.
How long does a leather strap last on a Longines Présence L4.790.4.12.6 with daily wear?
A quality leather strap, such as those crafted from vegetable-tanned leather, typically lasts 2-4 years with daily use. Longevity depends on humidity exposure, sunlight and the tanning method employed. MilanoStraps straps carry an 18-month warranty and can be serviced or replaced. Proper maintenance—avoiding prolonged water exposure and applying leather conditioners—significantly extends strap longevity.
