Frequently asked questions

What is the lug width of the Rolex Day-Date 36 128235-0063?

The lug width of the Rolex Day-Date 36 128235-0063 is exactly 20 mm. This measurement refers to the distance between the two attachment pins at the lugs of the Oyster case. It is essential to verify this dimension before purchasing a compatible strap, as a strap of different width will not fit correctly into the case attachments.

What is the best strap material for the Day-Date 36 128235-0063 in rose gold?

Alligator remains the most appropriate material for the Day-Date 36 128235-0063 in rose gold, thanks to its regular texture and its ability to develop a natural patina over time that harmonises perfectly with the warmth of rose gold. Alternative materials of quality include Chamonix calf and shell cordovan, both with more structured textures but equally elegant and durable.

How do you change the strap on the Rolex Day-Date 36 128235-0063?

The strap on the Day-Date 36 is changed using a specific tool to remove the spring bars (lug pins). It is recommended to consult a professional watchmaker or the Casati Milano service, which offers personalised guidance and correct replacement without risk to the Oyster case. Do not attempt to remove the pins without proper tools to avoid damage.

Is a 20mm aftermarket strap compatible with the Day-Date 36 128235-0063?

Yes, any strap with a 20 mm lug width is compatible with the Day-Date 36 128235-0063. However, quality and aesthetics vary significantly. MilanoStraps and Casati Milano offer artisanal high-quality straps specifically designed to enhance this timepiece, with guarantees on craftsmanship and durability.

What is the lifespan of a leather strap for the Day-Date 36?

A high-quality leather strap (alligator, calf, shell cordovan) made with vegetable tanning typically lasts 4–6 years with regular use and maintenance. Durability depends on exposure to UV rays, humidity, frequency of use, and care. Casati Milano offers an 18-month warranty on manufacturing defects and provides maintenance advice to extend the strap's lifespan.
