Strap for Seamaster Aqua Terra 150M Master Chronometer 34 Moonshine Gold / Grey

The lug width is 16 millimeters. It is measured perpendicularly between the two lugs of the case, excluding decorations, with a digital caliper or ruler. This dimension is mandatory to ensure proper fit and absence of play.

Alligator leather with vegetable tanning in chocolate brown or tobacco tones represents the most elegant choice. Alternatively, vegetable-tanned calf with aged patina offers everyday versatility while maintaining formal authority. For nautical use, a NATO in navy blue or anthracite gray with titanium deployant is ideal.

Use a spring bar tool to remove the spring bar pins—small metal cylinders positioned horizontally in the lugs. Gently push the tool inward to compress the spring, extract the pin, and remove the strap. Insert the new strap by aligning the holes with the pins, then reinsert the pins into their seat with the spring bar tool.

A quality leather strap, with vegetable tanning, lasts 3–5 years under daily wear conditions, depending on exposure to light, humidity, and perspiration. The patina develops progressively, and the strap can be serviced. Artisan ateliers such as Casati Milano offer 18-month warranty and specialized maintenance services.
