The Day-Date 36 128395TBR-0004 (aka: m128395tbr-0004), seen from the bench

The Day-Date 36 represents the evolution of the model introduced by Rolex in 1956, the first watch in the world to display the day and date in full. It is powered by the automatic caliber 3255 with chronometer certification, displaying hours, minutes, seconds, date and day of the week. The case measures 36mm with 20mm lugs.

Frequently asked questions

What is the lug width of the Rolex Day-Date 36 128395TBR-0004?

The lug width (ansa width) of the Rolex Day-Date 36 128395TBR-0004 is 20mm. This measurement refers to the internal distance between the metal pins that connect the case to the strap. A compatible strap must maintain construction precision within ±0.5mm to ensure perfect adhesion to the rose gold case. Measuring the lug width correctly is essential: use a digital calliper positioning the tips between the internal ends of the lugs.

Which strap is best suited to the Rolex Day-Date 36 128395TBR-0004?

For the 128395TBR-0004 in rose gold, the ideal strap is genuine alligator leather with specialised tanning, which enhances the luminosity of the precious metal. Natural alligator is the classic choice, whilst dark brown creates an elegant tonal progression. Alternatively, shell cordovan (horsebutt calf with vegetable tanning) develops a burgundy patina that dialogues perfectly with rose gold. High-quality European calf remains the versatile solution for those desiring lower maintenance whilst preserving formal elegance.

How do I change the strap on my Day-Date 36?

Changing the strap requires a specific tool to remove the pins connecting the case to the strap. Position the watch with the lugs facing upwards, locate the pin hole (small cylindrical opening between case and lug), and use a pin pusher or dedicated tool to push the pin laterally until detachment. Proceed with care: although rose gold is robust, it can scratch if subjected to incorrect pressure. Once the old strap is removed, align the strap's holes with the case lugs and reinsert the pins.

Can I use an aftermarket compatible strap on the 128395TBR-0004?

Yes, absolutely. An aftermarket quality strap constructed at 20mm lug width is perfectly compatible with the Day-Date 36 128395TBR-0004. Compatibility depends on construction precision: the strap lug must feature straight edges, uniform thickness and a tolerance of ±0.5mm against the nominal measurement. Selecting a craftsman familiar with Rolex geometry guarantees a result that preserves the aesthetic elegance of the original case, without premature pin wear.

How long does a leather strap last on the Rolex Day-Date 36?

The lifespan of a leather strap depends on the material and frequency of wear. A genuine alligator strap, crafted by a specialised artisan, lasts an average of 3–5 years with moderate daily use (4–5 days per week), developing a desirable patina over time. Shell cordovan tends to last slightly longer (4–6 years) thanks to fibre density. High-quality European calf guarantees 2–4 years before replacement is required, particularly if exposed to moisture, perspiration or extreme temperatures. Proper maintenance (periodic cleaning and protection from prolonged water exposure) significantly extends strap life.
