Strap for Seamaster Regatta 37th America's Cup

The model 216.92.46.73.10.001 features 20 mm lug width. This measurement is specific to large-diameter sports models (46.75 mm) and does not fall within standard catalog specifications of major manufacturers, requiring specialized artisanal solutions. Measurement should be taken from the outer shoulders of the spring bar tube.

The best pairings are natural alligator for sporty elegance, cordovan for chromatic depth, or vegetable-tanned leathers to develop patina over time. For technical solutions, a nylon Cordura NATO offers versatility. The FKM rubber strap is not recommended, as it would be redundant given the pronounced technical identity of the titanium and ceramic case.

The lugs of model 216.92.46.73.10.001 are secured via straight spring bars. Remove the spring bars using a spring bar tool (extraction upward), then insert the new strap by sliding the spring bars into the lugs. Use a Teflon mallet to prevent damage to the titanium.

A high-quality alligator or cordovan strap, with proper maintenance, has an average lifespan of 4-6 years with daily use. Vegetable-tanned straps soften over time, developing natural patina and extending perceived longevity.
