Strap for Datejust 36 Stainless Steel Domed / Oyster / Silver Floral

The lug width is 20mm. This width is specific to the Datejust 36 model and is critical for correct strap installation. Verify with a digital caliper by measuring the internal space between the two flanks of the stainless steel lug. An 18mm strap would be too loose and unstable, whilst a 22mm strap cannot be inserted.

American alligator with modern tanning is ideal: the fine and symmetrical grain creates the best aesthetic contrast with the polished stainless steel case. Vegetable-tanned leather offers excellent patina development over time. Shell cordovan provides audacious burgundy character. Choice depends on use: hot climates suggest FKM rubber; formal wear requires satin-finished black alligator.

Requires precision tools: a Rolex screwdriver (or equivalent 0.80mm for lug screws) and a stable workbench with direct lighting. Remove the original bracelet by inserting the screwdriver into the lateral lug holes and rotating the screw downward. Extract the lug pins carefully from the opposite side. Position the new strap, reinsert the pins, and tighten with balanced pressure. If uncertain, entrust the operation to a certified watchmaker.

Any strap with a 20mm lug width is compatible, provided it is constructed to artisanal standards with precise shoulder fit. MilanoStraps 20mm straps have been specifically designed for models like the Datejust 36, maintaining aesthetic coherence with the case proportion. Always verify that the shoulder hole is 20mm internal, not 20mm external.

Durability varies by tanning method and usage. Vegetable-tanned alligator in temperate climates lasts 4–6 years with visible but functional wear. Shell cordovan resists 5–7 years whilst maintaining elasticity. FKM rubber lasts 3–4 years before losing fluidity. Vegetable-tanned calf ages nobly for 6–8 years. Maintenance: protect from direct sunlight, avoid prolonged moisture, clean with soft cloth. Casati Milano offers an 18-month guarantee on manufacturing defects.
