Strap for Datejust 36 Stainless Steel / Everose / Fluted / Silver - Palm - Diamond / Oyster

The Rolex Datejust 36 reference 126231-0038 has a lug width of exactly 20 millimetres. This measurement defines the space between the case attachment pins and determines which straps and bracelets can be fitted. To verify this, remove the original bracelet and measure the distance between the case lugs using a digital calliper. Any compatible strap must respect this 20mm dimension.

For a Datejust 36 two-tone in rose gold and steel, dark brown or cognac alligator represents the most traditional and sophisticated choice, as it enhances the warmth of Everose gold. Bordeaux shell cordovan is ideal if you seek a patina that ages visibly. Vegetable-tanned calf leather offers breathability and lightness. FKM rubber remains the most versatile for alternating formal and sporty contexts. The choice depends on primary use and personal aesthetic preference.

To change the strap on your Datejust 36, remove the spring bars connecting the bracelet to the case using a spring bar tool. This tool applies lateral pressure to the pins, allowing you to extract them gently. Once removed from the old strap, the spring bars are inserted into the attachment holes of the new strap and then reinserted into the case lugs. We recommend having this operation performed by an authorised Rolex service centre or qualified professional to avoid damage to the case or pins.

Yes, you can use an aftermarket compatible strap provided it respects the 20mm lug width and is made from high-quality materials. Bespoke straps in alligator, shell cordovan or vegetable-tanned calf guarantee aesthetics and durability comparable to Rolex standards. It is important that the buckle (ardillon or deployante) is in 904L steel to maintain colour harmony with the two-tone case. A personalised strap made in an atelier allows you to choose the colour, leather type and clasp type according to your preferences.

The lifespan of a leather strap depends on several factors: leather type, frequency of use, exposure to moisture and perspiration, maintenance and climatic conditions. A high-quality alligator strap, with moderate use and regular maintenance, can last 5-8 years. Shell cordovan tends to last longer (7-10 years) as the leather is denser and more resistant. Vegetable-tanned calf, being softer, has an average lifespan of 3-5 years with heavy use. To extend the strap's life, avoid direct water exposure, remove the watch before swimming, and have the strap professionally cleaned and conditioned at least once a year.
