Lady-Datejust 279178-0018— lug 14mm

The lug width of the Rolex Lady-Datejust 279178-0018 is 14mm. This measurement is taken as the internal distance between the lugs at the strap attachment point using a digital calliper. It is specific to this reference and differs from the lug widths found on the 36mm or 41mm Datejust models.

For the Lady-Datejust 279178-0018 in 18-carat yellow gold, the most suitable straps are vegetable-tanned alligator in cognac or bordeaux tones, or shell cordovan for a smooth surface that develops a personal patina over time. Both complement the grain of the gold case. A yellow gold deployant clasp is the most technically and aesthetically coherent closure choice.

To replace the strap on the Lady-Datejust 279178-0018, use a fine-tipped springbar tool to release the spring bars from the 14mm lugs. Work on a soft surface to protect the yellow gold case and apply controlled lateral pressure. If in doubt, it is advisable to consult a watchmaker or visit the Casati Milano atelier.
