Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279178-0016?

The Rolex Lady-Datejust 279178-0016 has a lug width of 14 mm. This measurement is taken with a digital calliper positioned inside the two horizontal lugs at their narrowest point. Adhering precisely to this dimension is essential to ensure the correct fitting of any aftermarket strap.

What is the best strap for the Rolex Lady-Datejust 279178-0016 in yellow gold?

For an 18 ct yellow gold case measuring 28 mm, alligator leather in vegetable tanning is the benchmark choice in fine watchmaking: the belly grain enhances the finish of the precious metal. Alternatively, box-calf leather in cognac or bordeaux tones offers everyday versatility, while shell cordovan develops a patina over time that complements the yellow gold beautifully.

How do I change the strap on a Rolex Lady-Datejust 279178-0016?

To remove the original or aftermarket strap from the Lady-Datejust 279178-0016, you will need a spring bar tool to release the spring bars from the 14 mm lugs. Care must be taken to avoid scratching the yellow gold case: it is advisable to work on a watchmaker's cushion and, if you are not experienced, to entrust the operation to a professional watchmaker or the Casati Milano atelier.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279178-0016?

Yes, high-quality aftermarket straps compatible with the Rolex Lady-Datejust 279178-0016 are available. The key requirement is a 14 mm attachment with shaped ends to follow the curve of the Oyster bezel. Milanostraps.it offers a curated selection of handcrafted 14 mm straps made with certified materials and buckles proportioned to the 28 mm case.

How long does a leather strap last on a Rolex Lady-Datejust?

The lifespan of a leather strap on a Rolex Lady-Datejust depends on the material and how well it is maintained. A quality vegetable-tanned alligator strap, kept away from water and excessive perspiration and treated periodically with leather conditioner, can last between 3 and 7 years whilst retaining its aesthetics and structure. Calf leather typically has a slightly shorter lifespan, whereas shell cordovan is among the most durable thanks to the density of its fibres. Casati Milano straps come with an 18-month warranty against manufacturing defects.
