Strap for Big Crown Diamonds 34 Stainless Steel / Black / Bracelet

The lug width (or lug-to-lug measurement) of this model is 17.00mm. This dimension is not standard in contemporary watchmaking but is precise for watches with 34-36mm case diameters, ensuring correct visual proportions between case and strap. To verify the measurement, measure the distance between the lateral spring bars (the metallic protrusions on the case) using a calibrated ruler.

For this austere mechanical timepiece, we recommend a vegetable-tanned alligator in warm brown tones or a ribbed calf leather in vegetable tanning. Both enhance the robust character of the satin stainless steel case. For sporting or aquatic contexts, black FKM rubber is the most technically sound choice. Cotton NATO straps offer chromatic versatility and everyday practicality.

The strap is secured via spring bars positioned at the case extremities, aligned with the 17mm lateral lugs. To remove the strap: use a dedicated spring bar tool or fine needle; push the bar downward, compressing the internal spring; extract the bar from its seats. Insert the new strap, aligning the extremities with the lugs, and reinsert the bars. Ensure the spring clicks correctly into position.

All artisanal 17mm straps with compatible lug widths are suitable. Always verify the measurement before purchase: the lug width must match exactly 17.00mm hole-to-hole. The straps on milanostraps.it are available in alligator, shell cordovan, ribbed calf, and NATO, all compatible with the 17mm specification of this model.

A high-quality artisanal leather strap (alligator or calf in vegetable tanning) typically lasts 3-5 years with daily wear, with longevity varying depending on climate, humidity, and frequency of use. Natural leather ages visibly, developing patina and micro-fractures that impart character. To extend lifespan, avoid prolonged water immersion and occasionally apply leather balm. FKM rubber maintains elastic properties for 5-7 years of intensive use.
