Strap for HydroConquest 41 Automatic Chronograph Stainless Steel / Ceramic / Black / Bracelet

The lug width is 21 millimetres, the specific dimension for this reference. Measure with a calliper between the inner lugs, parallel to the dial. Always check the spring bar for oxidation that might prevent smooth insertion of a new strap.

Alligator with vegetable tanning offers sartorial elegance and robustness; vegetable-tanned calf provides flexibility and comfort; technical NATO fabric ensures impermeability to salt water; vulcanised rubber is ideal for tropical environments and water sports. Choice depends on intended use and aesthetic preference.

Remove the strap by observing the lug position. Gently extract the spring bar from the spring side. Insert the new strap, aligning the holes with the lug shoulders, then position the retention bar. Verify it is securely locked on both sides. Simple operation, executable at home with minimal tools.

Yes, 21mm straps of superior quality are perfectly compatible. MilanoStraps offers straps in alligator, calf, NATO and rubber, customisable in sizes, initials and thread colour. For a complete artisanal experience, Casati Milano creates bespoke straps with 18-month warranty.

A quality alligator or calf strap, with vegetable tanning, lasts 3-5 years in regular non-professional use. Continuous exposure to salt water accelerates wear; protect from repeated immersion. Natural patina evolves over time. Synthetic NATO fabric and vulcanised rubber have greater durability, up to 7-10 years with minimal maintenance.
