Strap for Day-Date 1806

The lug width of the Rolex Day-Date 36 reference 1806 DD is 20 mm. This measurement is taken between the inner edges of the lugs using a digital calliper, excluding the metal thickness of the lugs themselves. This is the correct specification to provide when ordering a compatible aftermarket strap.

For an 18-carat yellow gold case such as that of the Day-Date 36 1806 DD, an alligator strap in square grain Hornback or Mississippiensis is the most coherent choice given the watch's formal identity. Alternatively, a vegetable-tanned calf leather strap develops a patina over time that complements the warmth of the gold. For less formal settings, shell cordovan offers unmatched surface compactness and sheen.

The strap on the Rolex Day-Date 36 1806 DD is removed using a springbar tool inserted between the lug and the spring bar. Lateral pressure on the tip of the spring bar releases it from its housing in the lug. It is advisable to rest the case on a soft cloth and proceed carefully to avoid scratching the gold. The new strap is fitted by tensioning the spring bar on one side and compressing it to engage the opposite lug.

Yes. Any strap with a 20 mm attachment width and standard spring bars is compatible with the Rolex Day-Date 36 1806 DD. milanostraps.it offers a selection of handcrafted straps in alligator, calf leather, shell cordovan and rubber, made specifically for watches with a 20 mm lug width, with the option of a deployant clasp in metal matching the case.

Longevity depends on the type of leather and frequency of use. A quality alligator strap, kept away from moisture and rotated with other straps, can last between three and five years whilst retaining structural integrity and a well-maintained appearance. Vegetable-tanned calf leather develops character over time but is more sensitive to perspiration. Shell cordovan is among the most resilient leathers for daily wear. Casati Milano straps carry an 18-month guarantee covering manufacturing defects.
