Datejust 36 126233-0016— lug 20mm

The Rolex Datejust 36 126233-0016 features a lug width of exactly 20mm. This measurement is determined by the case geometry and is essential for strap compatibility: a strap even 1mm different will cause lateral instability or damaging tension. Always measure your lug by placing a ruler between the inner edges of the passants, at the base of the lug.

Alligator leather with vegetable tanning offers the highest aesthetic value and improves durably over time, developing a rich patina. Shaded calf provides discretion and suppleness. Shell Cordovan develops an extraordinary patina, transitioning from mahogany brown to tobacco hues. For daily use and versatility, vulcanised rubber straps guarantee complete water resistance without sacrificing formality. Your choice depends on lifestyle and watch frequency.

Strap replacement requires a specialised tool to extract the lug pins (spring bars). Position the watch on a soft surface, locate the small lateral holes beneath the lugs, insert the tool gently to release the pin, remove the old strap and insert the new one, ensuring the pins lock firmly on both sides. If inexperienced, Casati Milano's Milan atelier performs this with warranty.

Yes, if handcrafted with certified quality materials. Casati Milano straps, made in Italy from CITES alligator, shell cordovan, premium calf and 904L steel buckles, guarantee durability and finishing comparable to official Rolex components. An 18-month warranty covers production defects completely. Thousands of Rolex collectors use daily high-quality aftermarket straps without compromise.

An alligator or calf strap, vegetable-tanned, typically lasts 5–10 years with daily use, depending on frequency, climate and care. Shell Cordovan tends to last even longer due to fibre density. Maintenance—drying after exposure to water, annual conditioning with specific creams—significantly extends lifespan. Casati Milano straps include detailed care instructions and WhatsApp support to prolong longevity.
