Frequently asked questions

What is the lug width of the Longines Presence L4.921.2.18.8?

The Longines Presence L4.921.2.18.8 features a lug width of 20 millimetres. This is the distance between the two attachment points (lugs) where the strap connects to the case. To verify this measurement, position a digital calliper between the case lugs: it should read exactly 20 mm. It is essential to respect this dimension to ensure proper strap installation and secure wear of the timepiece.

Which strap material is best suited for the Longines Presence L4.921.2.18.8?

Alligator is the most recommended choice for the Presence: its natural and regular grain highlights the geometric purity of the case, creating a sophisticated and formal aesthetic pairing. Alligator ages beautifully, developing a patina that accompanies the natural wear of the steel case. Alternatively, shell cordovan offers a distinctive grain and remarkable capacity to develop character over time. Vegetable-tanned calf leather is a versatile and daily-wear option that guarantees comfort and extended durability.

How do I change the strap on the Longines Presence L4.921.2.18.8?

To change the strap on the Presence, you must remove the transverse pins (bars) connecting the strap to the case. Use a professional tool called a spring bar tool: insert the flat tip into the small slot on the side of the pin, applying gentle downward pressure to release the internal hook. Once the first pin is free, the strap can be slid out. Repeat the procedure on the opposite side. To install the new strap, reverse the process: reengage the internal hook and insert the pin through the case lug and the new strap.

Is the strap I'm looking for compatible with the Longines Presence L4.921.2.18.8?

A strap is compatible with the Presence if its width is exactly 20 mm. This measurement must correspond to the distance between the two attachment points on the case. Milano Straps offers a specialised collection of 20 mm straps, certified to fit the Presence and other Longines models with matching specifications perfectly. Before purchasing, always verify that the seller explicitly specifies the compatible lug width.

How long does a leather strap last on the Longines Presence L4.921.2.18.8?

The lifespan of a leather strap depends on the type of leather, frequency of use and care provided. A certified quality alligator strap typically provides 4–6 years of daily wear before showing significant signs of aging. Shell cordovan can last 7–8 years thanks to its superior structural density. Vegetable-tanned calf leather usually offers 3–5 years of intensive use. Prolonged exposure to moisture, direct heat and sunlight accelerates deterioration. Milano Straps offers an 18-month warranty on its handcrafted straps, covering any manufacturing defects.
