Frequently asked questions
What is the lug width of the Rolex Lady-Datejust 279138rbr-0026?
The Rolex Lady-Datejust 279138rbr-0026 has a lug width of 14mm. This measurement should be taken with a digital calliper positioned between the inner edges of the lower lugs on the 28mm case. It is a non-standard size that requires straps specifically produced for this dimension.
What is the best strap for the Rolex Lady-Datejust 279138rbr-0026?
For the Lady-Datejust 279138rbr-0026 in yellow gold, a smooth alligator leather strap in cognac or bordeaux tones is the most coherent choice given the case material. Box calf leather with vegetable tanning is preferable for daily wear, as it develops a personal patina over time. All straps must feature a 14mm lug width.
How do you change the strap on a Rolex Lady-Datejust 279138rbr-0026?
To remove the original Jubilee bracelet from the Lady-Datejust 279138rbr-0026, a fine-tipped springbar tool is required, inserted into the lug hole to release the spring bars. Care must be taken to avoid scratching the yellow gold case. The operation should be performed on a soft surface, and if in doubt, it is advisable to consult a qualified watchmaker.

How long does a leather strap last on a Rolex Lady-Datejust 279138rbr-0026?
The lifespan of a leather strap depends on the quality of the hide, care and frequency of use.
