Strap for Aquis Date 43 Stainless Steel / Blue / Rubber

The lug width of the Oris Aquis 01 733 7653 4135-07 4 26 34EB is 20mm. This dimension represents the distance between the two lugs on the case and determines which strap width is compatible. Always verify the measurement with a digital calliper, positioning it perpendicularly between the inner edges of the lugs at their deepest point.

The choice depends on usage. For formal contexts, we recommend alligator in dark tones (black, brown) with vegetable tanning for natural patina development over time. For technical-sports use and frequent diving, vulcanised rubber or NATO in cordura fully preserve the instrument watch vocation. Vegetable-tanned calf leather is versatile, creating personal visual narrative through ageing.

The change requires a dedicated spring bar tool to extract the fixing pins. Position the watch securely on a soft surface, identify the lug holes where pins are inserted, use the spring bar tool to gently compress the internal spring of the pin and extract it. Once removed from both lugs, the old strap comes free. Insert the new 20mm strap, position the pin in the seats and verify it is correctly locked.

All straps with 20mm lug width are compatible. On milanostraps.it you will find dyed alligator, vegetable-tanned calf, suede leather, NATO straps in technical fabric and vulcanised rubber. Each strap is available in multiple colours and finishes, customisable according to your aesthetic and functional preferences.

A quality leather strap (alligator, calf or suede) on a sports watch like the Aquis has an average lifespan of 3-5 years under moderate daily use. If exposed to humid climates, frequent immersion or intensive use, durability reduces to 1-2 years. Vegetable tanning ages naturally, creating patina: this is normal. To extend lifespan, we recommend avoiding prolonged contact with saltwater and cleaning periodically with a soft dry cloth.
