Frequently asked questions

What is the lug width of the Rolex Datejust 36 reference 116238-0073?

The lug width of the Rolex Datejust 36 116238-0073 is 20 millimetres, measured centre-to-centre between the lugs. This dimension is standard across the Datejust 36 and most Rolex sports models. Verifying this measurement before purchasing an aftermarket strap is essential, as even minor deviations compromise secure fitment and overall aesthetic integration.

Which strap material is best suited to a yellow gold Rolex Datejust 36 116238-0073?

Alligator remains the quintessential choice for a yellow gold Datejust 36: its tight, oblique grain scale pattern creates an intuitive chromatic synergy with the precious metal. Shell cordovan presents a sophisticated alternative for those who value patina development over time. Vegetable-tanned calf leather offers daily versatility, whilst leather NATO straps provide practicality and rapid changeover capability. The selection ultimately reflects your personal usage philosophy and aesthetic priorities.

How do I change the strap on a Rolex Datejust 36?

To change the strap on a Datejust 36, you must remove the spring bars that attach the strap to the lugs. Obtain a proper spring bar tool and proceed methodically: position the tool in the lateral groove of the spring bar, applying gentle, measured pressure until the spring releases. Extract the old strap carefully and align the new strap to the lugs, inserting the spring bar in sequential fashion. If unfamiliar with this procedure, consult a qualified watchmaker or artisan.

Can I use an artisanal aftermarket strap on a Rolex Datejust 36 116238-0073?

Absolutely. A high-quality artisanal strap affords exceptional control over leather selection, finish quality and longevity characteristics that OEM straps sometimes cannot guarantee. Ensure the lug width is precisely 20 millimetres, that spring bars are stainless steel of verified quality, and that the strap features proper keeper loops. Artisanal leather breathes and matures over time, establishing an authentic, tactile relationship between wearer and timepiece.

How long does a natural leather strap last on a Rolex Datejust 36?

Durability depends on leather grade and daily usage intensity. A well-maintained artisanal alligator or shell cordovan strap endures 5–7 years of daily wear, developing distinctive patina and character. Vegetable-tanned calf typically survives 3–5 years before exhibiting visible wear markers. Natural leather is not permanent by design—this impermanence is, paradoxically, its greatest virtue: every scuff and discolouration chronicle your relationship with the watch. Light conditioning with neutral balms extends strap lifespan considerably.
