Strap for Divers Sixty-Five 40 Social Club Edition / Beijing

The lug width is 20mm, measured between the two lugs on the case. This dimension is non-standard among contemporary diving watches and requires dedicated straps to avoid visual imbalance.

An alligator strap tanned vegetable brown creates ideal contrast with the bronze bezel and develops natural patina over time. For underwater use, a cotton NATO or FKM rubber strap offers superior diving performance.

Use a spring bar removal tool. Position the tool under the spring bar, fully extract it from one side, then insert the new strap and click the bar into position. The process takes approximately 2-3 minutes per side.

No. A 22mm strap is incompatible with the 20mm lugs on this model. The case would appear disproportionate and the spring bars would not seat correctly. Use only 20mm compatible straps.

A vegetable-tanned leather strap has an average lifespan of 5-7 years with regular use and proper care. Exposure to salt water reduces durability to 2-3 years. Regular maintenance with dedicated balms significantly extends leather life.
