Strap for Aquis Chronograph 46 Stainless Steel / Black / Rubber

The lug width is 26mm. This measurement represents the internal space between the two lugs where the strap attaches. Verify the measurement by placing a digital calliper perpendicular to the case at the level of the spring bar holes to ensure compatibility with aftermarket straps.

The 46mm Aquis accommodates multiple options: alligator or vegetable-tanned calf leather straps for formal elegance, Cordura NATO straps for tactical practicality, and FKM (Viton) rubber straps for extended diving. Your choice depends on usage context: professional, recreational, or professional aquatic.

Remove the strap by unscrewing the spring bars with a dedicated tool. Position the spring bar remover perpendicular to the bar and apply controlled pressure until the internal spring releases, then remove the old strap. Insert the new strap into the lug seat and reinsert the bars, ensuring the spring sits correctly to prevent positional loss.

Yes, quality-certified straps with 26mm lug width are fully compatible. However, verify not only the width but also the thickness and rigidity relative to the case's original design. Undersized straps create play; oversized straps prevent flush mounting with the case.

A quality, naturally-tanned leather strap typically lasts 3–5 years in recreational-sports use, reducing to 1–2 years if frequently exposed to salt water without rinsing. FKM rubber exceeds 5–7 years but requires monthly cleaning to maintain elasticity. Technical-fibre NATO straps can exceed 10 years with minimal maintenance.
