Strap for Presence 37 Automatic Gold

The lug width of the Longines Presence L4.787.6.11.2 is 18 millimetres. This measurement is precise and allows no tolerance: the strap must be exactly 18mm to fit correctly into the watch lugs without risk of damage or instability. Correct measurement is performed by placing the calliper perpendicular to the lug, between the inner shoulders of the case, excluding the attachments.

For the Longines Presence L4.787.6.11.2 in yellow gold, alligator leather represents the ideal formal choice, preferably in dark brown, cognac, or black tones. Vegetable-tanned calf is an elegant alternative, as is shell cordovan in deep brown. The recommended colours enhance the warmth of the noble metal without competing visually. Avoid bright shades, navy blue, or cream, which create chromatic dissonance with gold.

To change the strap, position the watch on a soft surface with the case facing upward. Use a dedicated spring bar tool to push the small spring lug inward, releasing the metal tube from the lug. Repeat this operation on both sides. Insert the new 18mm strap by snapping the attachments into the lugs until fully locked. Verify that the strap is secure before wearing the watch.

Yes, the Longines Presence L4.787.6.11.2 is fully compatible with quality artisanal aftermarket straps, provided they respect the 18-millimetre lug width. Straps in alligator, calf, shell cordovan, or other noble materials can be used without compromising functionality. It is advisable to choose manufacturers specialising in luxury watches to ensure construction precision and longevity.

The lifespan of a leather strap depends on material quality, daily use, and maintenance. A high-quality alligator or calf strap typically lasts 3-5 years with regular use. Vegetable-tanned leather tends to age by developing patina, visually extending the perception of value. Exposure to moisture, extreme heat, and perspiration accelerates wear. Proper maintenance – periodic cleaning and drying – significantly extends strap life.
