Strap for Seamaster Aqua Terra 150M Master Chronometer 34 Sedna Gold / Diamond / Wave Ruby / Bracelet

The lug width is exactly 16mm. This measurement represents the internal distance between the case lugs and corresponds to the width that the strap must have to fit perfectly without play or tension. Verifying this measurement with a digital caliper before purchase is essential to ensure complete compatibility.

Smoked alligator in brown tones is the natural complement: the grainy texture dialogues with the teak-pattern dial. Alternatively, cognac shell cordovan ages beautifully, reflecting the chromatic evolution of Sedna Gold over time. For summer practicality, natural FKM rubber offers durability and resistance to moisture absorption.

Use a dedicated tool (spring bar tool) to compress the pins that secure the strap to the lugs. Work on a soft, well-lit surface to avoid scratches. If you are not experienced, Casati Milano offers strap change service at the atelier with free evaluation of the case and fastening mechanism.

Yes, provided the strap has a certified lug width of 16mm and appropriate length for your wrist (standard 20cm for single cut, customizable).

A high-quality leather strap (alligator, shell cordovan, vegetable tanning) lasts 18-36 months with daily use, developing patina and character over time. The natural stretching of leather may require length adjustments every 12-18 months. Casati Milano offers renewal services and pin replacement on a recommended schedule.
