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

The lug width of the Anonimo Nautilo AM-1002.11.007.A16 is 20 mm. This measurement represents the distance between the two lateral spring bar attachments where the strap connects to the case. A 20 mm strap fits perfectly without undesirable tolerances, maintaining harmonious aesthetics between the 44.40 mm case and replacement accessories.

For the AM-1002.11.007.A16 model, we recommend three primary options: (1) alligator in dark cognac tone for lasting elegance and natural patina over time; (2) vegetable-tanned calf in dark brown for conscious texture and personalised colour evolution; (3) vulcanised rubber in black for tactical and sports use with maximum cleaning ease and resilience. Selection depends on predominant usage: formal, daily, or professional.

The strap on the AM-1002.11.007.A16 is changed by removing the spring bars (lateral spring pins) from the case lugs. Use a spring bar tool to compress the spring and carefully extract it from the seats. Once the old strap is removed, insert the new one by aligning the spring bars into the lateral holes until you feel the locking click. Avoid forcing to prevent damage to the metal lugs. This operation takes a maximum of 2-3 minutes and can be performed without specialised tools if handled with care.

Yes, any strap with a 20 mm lug width is compatible with the AM-1002.11.007.A16. Compatibility is guaranteed by the standardised spring bar size and attachment geometry. However, for optimal aesthetic results, we recommend straps specifically designed for large watches (40+ mm) with adequate thickness (3.5–4.5 mm) to maintain visual balance with the robust case.

Leather strap durability varies based on material and usage: a high-quality alligator or calf strap with vegetable tanning typically lasts 3–5 years with moderate daily wear. Synthetic leather or chrome-tanned straps have slightly shorter lifespans (2–4 years). Wear depends on factors such as sun exposure, humidity, wearing frequency, and proper maintenance (regular cleaning, seasonal waterproofing). Natural ageing signs are desirable in vegetable-tanned leather, but when fibres begin delaminating or cracking, it is time to replace the strap.
