Day-Date 36 118235f-0055— lug 20mm

The lug width (ansa width) of the Rolex Day-Date 36 118235f-0055 is 20 millimetres. This dimension is measured between the two attachment points of the lugs on the case and is essential for strap compatibility. A strap with an 18mm or 22mm lug width will not fit correctly and may cause instability or risk of losing the watch.

For this Everose model, the most recommended materials are satin-finished alligator in dark brown or grey tones (which complements the rose gold naturally), vegetable-tanned calf leather for superior durability, or shell cordovan for those seeking natural water resistance and timeless lustre. Alligator remains the formal choice par excellence and reflects the presidential philosophy of the model.

Strap replacement is accomplished by removing the spring bar that connects the lugs to the case. A spring bar tool is used to press the pins of the spring bar and release the lugs from the attachment points. It is advisable to have the operation performed by an experienced watchmaker to avoid scratching the case or damaging the spring bar.

Yes, provided it is specifically dimensioned for a 20mm lug width. Many artisanal leather straps in premium leathers, vegetable-tanned or cordovan materials are compatible with the Day-Date 36. It is essential to verify the lug width before purchase and choose suppliers who understand the aesthetic proportions required by a timepiece of this calibre.

A high-quality alligator strap, with proper care, typically lasts 3-5 years. Shell cordovan and vegetable-tanned calf leather can achieve 5-7 years of service due to their natural resistance to wear. Durability depends on ambient humidity, sun exposure, frequency of wear, and maintenance. Superior quality straps require less maintenance; lower-grade leather straps deteriorate more rapidly.
