Strap for Rectangular Day Date 30 Stainless Steel / Black

The lug width of the Oris Rectangular 01 585 7525 4064-07 5 20 44FC is 20mm. This measurement indicates the distance between the two lateral case lugs, measured from inside to inside. For strap compatibility verification, precise measurement using a calliper or metal ruler is essential, as even minor discrepancies prevent proper fitting.

Selection depends on usage and aesthetic preference. For versatile elegance, a vegetable-tanned leather strap develops character over time. For luxury and durability, alligator leather is ideal with superior water resistance. For casual versatility, a satin cotton NATO maintains the watch's instrumental character. For sports use, FKM rubber offers water resistance and long-lasting comfort.

The strap is mounted and removed via the lateral case lugs. Use a spring bar tool (dedicated extraction instrument). Insert the thin blade into the lug slot, gently press downward to release the spring, and the strap disengages. For installation, align the new strap's holes with the lugs, reinsert the spring bar using the tool, and verify secure fastening on both sides.

Yes, numerous options exist. The 20mm lug width is widely available in the bespoke strap market. Always verify that the selected strap specifies 20mm compatibility, as this is the only size that properly fits this Oris model. Milanostraps offers a dedicated collection of 20mm straps in various materials and colours.

A quality leather strap (European calf or shell cordovan) typically lasts 3-5 years with daily use, considering routine maintenance. Longevity depends on frequency of use, humidity exposure, and tanning method. Vegetable-tanned straps deteriorate faster with water contact, whilst alligator resists moisture better. With proper care (drying after water exposure, occasional conditioning), lifespan can extend considerably.
