Datejust 36 116200-0094— lug 20mm

The Rolex Datejust 36 116200-0094 features a lug width of 20 millimetres. This is the distance between the pins that connect the strap to the watch lugs. It is critical to verify this exact measurement when purchasing an aftermarket strap, as even 0.5mm of variance can cause either play or resistance in the fit.

There is no universal answer; it depends on use case and personal aesthetics. For formal contexts, alligator with vegetable tanning is ideal; smooth calf offers understated elegance; shell cordovan provides structural rigidity over time. For a 36mm watch, we recommend straps with a thickness of 3.5–4.5mm and harmonious curves that respect the delicate proportions of the case.

Position the watch on a soft cloth with the case facing down. Locate the lug (the strap support) and observe the small pin connecting it to the strap. Use a spring bar tool—a dedicated instrument with two curved tips—to compress the inner pin from above, creating sufficient space to extract the strap end. Repeat on the opposite lug. Never use screwdrivers or sharp metal objects that could scratch the case.

Yes, if manufactured correctly. A bespoke 20mm strap, constructed with anatomical lugs and a passage proportioned to the 36mm case, ensures a perfect fit. However, construction quality varies: a poorly made strap may cause lateral movement despite the correct width. We recommend artisans who measure the watch before production.

Lifespan depends on leather quality and usage. A high-quality alligator strap with vegetable tanning and natural tannins lasts 5–8 years with regular maintenance (annual conditioning, air-drying after sweat contact). Calf, being softer, may fail sooner, around 3–5 years. Shell cordovan, due to its natural density, often exceeds 10 years. The most common failure occurs at the passage, where mechanical stress is greatest.
