Strap for Nautilo Automatic Stainless Steel / DLC / Black / Canvas

The lug width of the Anonimo Nautilo AM-1002.13.113.T34 is 22mm. This dimension, measured centre-to-centre between the case lugs, is an industry standard that grants access to a vast range of artisanal straps. To verify strap compatibility, ensure the strap is marked or specified as 22mm. All straps in the Milano Straps 22mm collection are guaranteed compatible with this model.

The choice depends on intended use. For formal contexts, matte black alligator maintains maximum aesthetic cohesion with the raw stainless-steel case. For aquatic use, FKM or silicone rubber offers salt-water resistance and rapid drying. For daily versatility, vegetable-tanned calf introduces a patina that evolves over time. For those preferring a military-operative character, a NATO strap in Cordura canvas—grey or OD green—is the most authentic choice. Milano Straps offers bespoke prototypes at the Casati Milano Atelier for direct consultation.

Strap replacement on a Nautilo with 22mm lugs is performed by removing the spring bars that connect the strap to the case. Using a dedicated spring-bar tool, gently push the bar upward from the bottom, leveraging one end. Once released, the old strap detaches. Insert the spring bar into the new strap, position the first end in the upper lug hole of the case, then lower the bar from above until it seats. Repeat for the other end. Verify the strap is securely fastened and does not rotate. If you prefer to avoid DIY installation, Casati Milano Atelier offers mounting service by appointment.

Yes, provided the strap is specifically designed for a 22mm lug width. Milano Straps artisanal straps are all compatible with this dimension. We recommend verifying that the strap matches the width (22mm) and that the holes are properly drilled to accommodate your case's spring bars without excessive play. Artisanal-quality straps such as alligator, shell cordovan, or vegetable-tanned calf will significantly enhance the wearing experience compared to standard industrial straps.

The lifespan of a leather strap depends on material, tanning method, and usage. Vegetable-tanned calf typically lasts 3–5 years with daily wear and regular care. Shell cordovan, denser and more resilient, can exceed 7 years. Alligator, with its finer grain, requires UV protection and typically lasts 4–6 years. Factors reducing lifespan include frequent salt-water exposure (rubber recommended in such cases), accumulated sweat without cleaning, and excessive flexing. Periodic maintenance—dusting, protective treatment every six months—significantly extends lifespan. Rubber and NATO straps typically last 5–8 years under standard conditions.
