Strap for Da Vinci Perpetual Calendar Digital Date-Month Rose Gold

The IWC Da Vinci IW3761-02 has a lug width of 24mm. This measurement is precise and non-negotiable: any strap must respect exactly this dimension to ensure correct seating on the rose gold case lugs. It is measured with a digital caliper by calculating the internal distance between the two case terminals.

For the rose gold IW3761-02, we recommend black alligator (aristocratic solution), aged hammered calf (with patina that evolves over time), or shell cordovan for those desiring a strap that acquires natural lustre. Each material dialogues differently with rose gold: noir alligator creates formal austerity, calf communicates confidence, shell cordovan intensifies chromatic depth.

Changing the strap on the Da Vinci IW3761-02 requires just a few steps: position the watch with the strap facing upward, locate the push buttons (small lateral buttons at the lugs), press gently inward with a specific tool (spring bar tool or strap removal tool) to release the retaining spring, remove the old strap, align the new strap so that the terminals enter the lugs, and press until you hear the spring locking click. Operation takes 30 seconds per side.

Yes, any strap with 24mm lug width is compatible with the IW3761-02. Milano Straps offers a collection of 24mm aftermarket straps in alligator, calf, shell cordovan, NATO and rubber, all customizable in size, colour and stitching thread. Verify that the strap is specifically produced for 24mm lug width and that the length is suitable for your wrist.

Durability depends on the tanning and usage. An alligator with vegetable tanning well maintained lasts 5-8 years with moderate daily use. Shell cordovan, more resistant, reaches 8-10 years. Standard calf lasts 3-5 years. Longevity increases significantly if the strap is not exposed to prolonged moisture, frequent washing or excessive mechanical wear. The Casati Milano atelier offers an 18-month warranty on custom straps made to measure.
