Strap for Presence 34.5 Automatic Pink Gold

The lug width (misura ansa) of the Longines Presence L4.778.8.12.0 is 19 millimetres. This is the distance between the two internal attachment points of the case where the strap inserts. You can verify this by measuring the inside of a lug with a digital calliper. This measurement is standard for Longines Presence dress watch models.

Medium brown or cognac alligator is the classic choice for rose gold, as the natural grain reflects light in harmony with the case. Alternatively, deep red shell cordovan creates absolute formal elegance thanks to its natural lustre. Black vegetable-tanned calf is perfect if you desire maximum contrast. Avoid sporty rubber or NATO straps, which diminish the dress character of the watch.

Strap replacement is done via the spring bars. Position the watch face-down on a soft pad and use a strap tool or small artisanal lever to gently compress the small elastic catch on the spring bar; once the bar is released, withdraw it completely. Repeat on the other side. To insert the new strap, align the strap holes with the spring bars and compress until you hear a click. Never force: if a bar won't enter, the lug width is incorrect.

Yes, any strap manufactured for the 19mm lug width is compatible, provided it has been made with millimetre precision. The milanostraps.it artisanal straps for the 19mm measurement are specifically designed for this lug width. Ensure the strap is not too rigid (during the first month of use) and that the attachment holes are perfectly aligned with the spring bars of your case.

A high-quality leather strap (alligator, calf, shell cordovan) lasts an average of 2–4 years if worn daily, or 5–7 years if worn occasionally. Longevity depends on exposure to moisture, perspiration and mechanical stress. A vegetable-tanned strap naturally develops a patina, gaining character. milanostraps.it straps include an 18-month warranty and can be restored via the Casati Milano atelier.
