Strap for Speedmaster Day-Date 40 Yellow Gold / Silver

The lug width is 19mm. This measurement must be respected precisely when selecting a replacement strap to ensure perfect attachment to the watch case without play or forcing.

Alligator in cognac or dark brown tones represents the most aesthetically fitting choice, as it naturally complements the warm reflections of yellow gold. Vegetable-tanned calf offers a sophisticated alternative with characteristic aging. For summer daily wear, navy NATO maintains the professional identity of the instrument.

Using a flat end (spring bar tool or specific tool), apply gentle pressure to the spring lug positioned underneath the strap itself. The spring yields, releasing a metal pin that allows strap extraction. The process is reversible and does not require sophisticated tools; Casati Milano recommends proceeding with caution to avoid scratching the gold case.

Yes, any strap with a 19mm lug width is compatible. Milanostraps.it offers a wide range of artisanal straps in this size, customizable in leather, colors, lengths, and thread stitching. It is important to always verify the lug width before purchase.

The durability depends on the material and usage. A superior quality alligator resists 5-7 years with daily wear. Vegetable-tanned calf ages thanks to natural patina and with appropriate maintenance can last 3-5 years. Shell cordovan, being denser leather, tends to preserve longer. The Casati Milano atelier provides an 18-month warranty on all made-to-measure straps.
