Strap for Presence 23.5 Quartz Yellow

The lug width of the Longines Presence L4.220.2.12.7 is 12mm, a specific non-standardised measurement. This dimension was calibrated by Longines to maintain correct visual proportions with the 23.50mm case. To verify the measurement, use a digital calliper to measure the external distance between the two lug pins. It is important not to confuse this measurement with other common sizes (14mm, 16mm, 18mm), as a strap not dimensioned correctly may not adhere stably to the case.

The Longines Presence L4.220.2.12.7 achieves aesthetic excellence with alligator straps of vegetable tannage, which enhance the sobriety of the case through subtle texture and patina that evolves over time. An equally high-quality alternative is Hermès-grade calf leather, particularly appreciated for its ability to develop rich patina. For dirtier or summer use, a grained rubber Tropic maintains elegance without sacrificing practicality. The choice depends on intended use and the colour palette you wish to match with the stainless steel case.

To change the strap on a watch with 12mm lugs, proceed as follows: 1) Position the watch on a soft surface (microfibre cloth). 2) Locate the visible lug pins on the sides of the case. 3) Use a dedicated spring bar removal tool to push the pin inward, releasing one end of the spring. 4) Remove the old strap. 5) Align the new strap with the watch lug and insert the pin into the new leather hole. 6) Press gently until the pin engages with the second lug. It is advisable not to force excessively; if the pin does not enter smoothly, verify that the strap is correctly dimensioned for 12mm lugs.

Yes, provided the strap is expressly constructed for 12mm lugs. The majority of aftermarket straps on the market are dimensioned for standard sizes (14mm, 16mm, 18mm), and therefore will not be compatible. Milano Straps offers a dedicated collection of 12mm straps, available in alligator, calf, rubber and shell cordovan, all constructed with precise tolerances and standard spring bar pins. Aftermarket compatibility is guaranteed only when the manufacturer explicitly specifies the 12mm lug width.

A natural leather strap of quality (alligator, vegetable tannage calf) has an average lifespan of 3-5 years with moderate daily use, extendable to 7-10 years with correct maintenance and non-daily use. Factors that influence longevity include: 1) Water exposure (it is advisable to avoid it, given that the Presence has 30m water resistance). 2) Relative humidity (dry environments prolong life). 3) Frequency of use. 4) Sun exposure (UV degrades fibres). 5) Tannage quality (vegetable is more durable than synthetic). Milano Straps offers 18 months warranty on artisanal straps and recommends alternating use among multiple straps to distribute wear.
