Strap for Khaki Navy Scuba Auto Stainless Steel / Black / Bracelet

The lug width of the Hamilton Khaki Navy H82335131 is 20mm. This specification is critical for strap compatibility: any strap you purchase must have a lug width of exactly 20mm to fit the case lugs without play or forcing.

The choice depends on your intended use and aesthetic preference. For this model's dress-sports profile, we recommend an alligator strap with vegetable tanning (dark brown or black), a shell cordovan for those seeking deep patina development over time, or a NATO in ballistic canvas to emphasise its instrumental vocation. A fine-grain calf leather offers versatile balance between elegance and practicality.

Strap replacement requires a springbar removal tool. Locate the springs (springbars) beneath the case lugs, gently compress the removal tool to extract the spring from one side, slide out the old strap, then insert the new strap and allow the spring to click into place. We recommend working over a soft surface to avoid scratching the case.

Yes, any strap with a certified 20mm lug width is compatible with the H82335131. Bespoke straps offer advantages in customisation (leather, colour, finishing) and superior construction quality over mass-produced alternatives. Always verify that the supplier specifies 20mm lug width and that the measurement is taken accurately between the inner edges of the lugs.

A quality leather strap (alligatore, shell cordovan, vegetable-tanned calf) typically lasts 3–5 years with regular daily wear, provided minimal maintenance: avoid prolonged immersion and dry it after moisture contact, occasionally apply leather conditioners to natural leather. Shell cordovan straps resist longer and develop beautiful patina. Canvas NATO straps have greater longevity but require less maintenance.
