Date 1500— lug 19mm

The Rolex Date reference 1500 has a lug width of 19mm. This measurement differs from the 20mm found on the contemporaneous Datejust line and is specific to this 34mm case. For an accurate measurement, use a digital calliper positioned between the inner walls of the lugs, as close to the case as possible.

The most suitable straps for the Rolex Date 1500 are cross-grain alligator in tobacco or cognac tones, or vegetable-tanned calf leather that develops an authentic patina over time. For everyday or sporting use, a nylon NATO strap or a vulcanised rubber strap are practical alternatives that remain historically consistent with the watch's production era.

To replace the strap on a Rolex Date 1500, you will need a dedicated 0.8mm springbar tool. Insert the tool into the lateral hole of the lug or between the strap and the case to compress the spring bar. Care should be taken not to scratch the steel case surfaces; work on a soft mat and, if in doubt, entrust the operation to a qualified watchmaker.

Yes, a wide range of aftermarket straps are compatible with the Rolex Date 1500, provided they feature a 19mm lug width. It is essential to verify the exact measurement before purchasing, as many generic straps are produced in 20mm and will not fit the lugs correctly. Casati Milano handcrafted straps are made to measure to ensure a precise fit and a finish befitting the value of the timepiece.

The lifespan of a leather strap depends on the material, frequency of use, and care taken. A quality vegetable-tanned calf strap, used attentively and kept away from prolonged contact with water or perspiration, will typically last 2–4 years. Alligator or shell cordovan straps, owing to the greater density of their fibres, tend to last longer — up to 5–7 years — developing a distinguished patina in the process.
