Strap for Aquis Date 39.5 Stainless Steel / Green / Bracelet

The lug width of the 01 733 7732 4137-07 8 21 05PEB is precisely 20mm. This measurement is taken from the centre of one spring bar to the centre of the other and determines strap compatibility. All aftermarket straps designed for this Aquis model must accommodate a 20mm lug width.

Material choice depends on intended use. For formal elegance, we recommend vegetable-tanned alligator, which develops unique patina over time. For everyday versatility, chrome-tanned or aniline calf maintains consistent aesthetics without colour shift. For aquatic sport or humid environments, rubber or FKM straps ensure complete waterproofing. For military-inspired practicality, canvas NATO offers quick changes and rapid drying.

Remove the strap by extracting the two spring bars that secure it to the watch lugs. Using a spring bar tool, apply gentle pressure to compress the bar, then withdraw it. Insert the new strap by aligning the holes with the bars and gradually release the tool. The procedure takes minutes and requires only a basic spring bar tool.

Yes, completely compatible. All certified 20mm straps in the Milanostraps collection are compatible with reference 01 733 7732 4137-07. Each strap is tested for lug width accuracy and construction quality. Our artisans guarantee bespoke finishing and premium leather or textile materials.

A vegetable-tanned natural leather strap, with regular maintenance, lasts 4–7 years of daily wear. Longevity depends on frequency of use, humidity exposure and care. Leather naturally wears on the passant and buckle, not on the wrist-contact section. Rubber straps last 5–8 years; durable canvas NATO 6–10 years.
