Strap for Big Crown Pointer Date 30 Stainless Steel - Rose Gold / Black

The lug width (strap width) of this Oris Big Crown model is 15mm, which is a less common standard compared to 16, 18, or 20mm. This specific measurement was chosen by Oris to maintain the elegant proportions of the 30mm case diameter. To verify the measurement with precision, use a digital calliper, measuring the internal space between the two lugs of the case: the value should be exactly 15mm.

For this 30mm Big Crown, the most appropriate straps are: alligator leather with vegetable tanning for a formal-traditional look that develops patina over time; structured calf leather in medium grain to emphasise the aviatory character; NATO in cordura for daily versatility. Avoid excessively thick straps, as the 15mm width and compact case diameter do not allow for this. We recommend consulting Casati Milano for bespoke personalisation to measure.

To change the strap on the 01 584 7626 4364-07 5 15 76FC: use a spring bar tool (standard tool with silicone tips to avoid scratching); gently lift the lugs outward; completely extract the spring bars from their seats; align the new strap with the lugs; reinsert the spring bars so they snap securely into their final positions. If you feel uncertain, entrust the task to a specialised watchmaker to avoid damage to the case.

Yes, 15mm aftermarket straps are available from specialist retailers such as Casati Milano, which offers straps in alligator, calf leather, NATO, and rubber specifically made for this lug width. Thanks to bespoke craftsmanship to measure, Casati Milano guarantees perfect compatibility and artisanal finishes that exceed standard options. Online personalisation allows you to choose material, colour, and buckle type.

A high-quality leather strap (alligator, calf, shell cordovan) with vegetable tanning lasts approximately 3–5 years with daily use, depending on environmental conditions, sun exposure, and humidity. Longevity increases if cared for: keep it dry, avoid prolonged perspiration contact, occasionally apply specific balms. A NATO strap in fabric lasts longer (5–8 years) but requires minimal maintenance. The rarity of the 15mm width does not compromise durability: Casati Milano uses premium leathers that age beautifully and nobly over time.
