Strap for Divers Sixty-Five 40 Stainless Steel / Deauville Blue / Rubber

The lug width of this model is exactly 20 millimetres. This dimension represents the internal space between the two lugs at the 12 and 6 o'clock positions. Precise measurement is critical when purchasing compatible straps: it ensures the strap seats without forcing and without excessive play.

The optimal choice depends on intended use. For elegance, we recommend alligator treated with vegetable tanning or shell cordovan for its extraordinary patina development. For daily aquatic resistance, a thick vegetable-tanned leather (minimum 1.4 mm) is ideal. For intensive humid environments, nylon NATO or FKM rubber offer superior practicality. A deployant clasp ensures comfort on these models.

Use a spring bar removal tool to extract the spring bars from the case lugs. Insert the flat end of the tool beneath the bar, applying pressure to compress the internal spring and disengage the end from the lug. Repeat on the opposite side. Insert the new strap by aligning the holes with the bars and allowing the spring to re-engage.

Yes, provided the lug width is exactly 20 millimetres. We recommend quality straps from specialist suppliers who guarantee precise tolerances. Avoid straps with approximate measurements (for example, 19.5 or 20.5 mm): they cause bezel instability and accelerated wear on the lugs.

A quality vegetable-tanned leather strap lasts 18-30 months with daily wear, provided moderate moisture exposure. Saltwater accelerates deterioration: with frequent immersions, expect replacement every 12-18 months. Shell cordovan, being denser, reaches 40+ months. Natural patina improves during the first 12 months of use.
