The Datejust 36 116233-0174, seen from the bench

The Rolex Datejust 36 reference 116233-0174 is a two-tone timepiece combining yellow gold and stainless steel, featuring the Rolex 3135 automatic movement with Parachrom hairspring and Chronometer certification (±4 seconds/day). The 36mm case diameter represents the classic Datejust standard, with a 20mm lug width for strap attachment. The smooth bezel, date window at 3 o'clock, and Perpetual crown enable manual date adjustment, balancing formal and casual wear with its warm gold lugs contrasting against the steel case back and middle case.

Frequently asked questions

What is the exact lug width of the Rolex Datejust 36 116233-0174?

The lug width of the Rolex Datejust 36 116233-0174 is 20 millimetres. This specification corresponds to Rolex's manufacturing standard for 36mm Datejust models, whether in two-tone or full gold. The factory tolerance is ±0.2mm, so any strap certified for 20mm will install with precision on the spring bars without lateral play.

Which strap material is most suitable for the two-tone Datejust 36 116233-0174?

For the yellow gold and steel combination, we recommend three complementary options: dark brown alligator (Hermès grade or better) for formal elegance, cognac calf leather for daily versatility with visible patina development, or grey twill NATO for refined sporty contexts. Alligator emphasises the nobility of the case metals, calf leather dialogues with the warmth of the gold, and NATO modernises the classic presentation. Avoid straps with excessively coarse texture, which clashes with the refined proportions of the 36mm case.

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

Strap replacement requires minor attention: place the watch on a soft cloth with the case facing upwards. Locate the two spring bars that pass through the lugs. Using a spring bar tool or small rounded-tip screwdriver, gently press inward on one end of the bar until the spring releases. Repeat on the opposite side. Extract the old strap and insert the new one, ensuring the bar clicks firmly into the lug slots. If unsure, consult a qualified watchmaker: the service typically costs £12–£25.

Is a quality aftermarket strap compatible with the Datejust 36 116233-0174?

Yes, provided the declared lug width is 20mm and construction tolerances meet standard specifications. Straps in alligator, cordovan, calf leather and even certified vegetable-tanned parchment are entirely compatible. What differs is longevity: an artisanal Italian strap in vegetable-tanned leather maintains elasticity and patina for 4–5 years of moderate daily use, whereas budget synthetics degrade within 12–18 months.

What is the typical lifespan of a natural leather strap on a Rolex Datejust?

A quality artisanal leather strap — such as alligator, shell cordovan or vegetable-tanned calf — typically lasts 3–5 years with moderate daily use (5–6 days per week). Visible patina after 8–12 months is normal and desirable, a sign of authentic leather that breathes. To extend lifespan, alternate the strap with a NATO or rubber option during weekends, avoid prolonged exposure to stagnant fresh water, and apply a leather conditioner every 6–8 months.
