Strap for Aquis Date 43.5 Stainless Steel / Upcycle

The lug width of the Oris Aquis 01 733 7789 4150-07 8 23 04PEB is 23mm. This measurement represents the distance between the two metal lugs of the original bracelet and is essential for ensuring compatibility with aftermarket straps. The 23mm width has been calibrated by Oris to achieve optimal proportions with the 43.50mm case.

For the 01 733 7789 4150-07 8 23 04PEB model, we recommend a vegetable-tanned alligator strap for formal wear, calf leather for everyday versatility, or NATO fabric for sports contexts. The choice depends on primary use: exotic leathers emphasise the case's nobility, whilst technical straps preserve the watch's instrumental identity.

To change the strap, use a spring bar removal tool: insert the forked tip into the side spaces of the lug spring, apply gentle outward pressure, and slide the strap free. Install the new strap by aligning the bar holes with the lugs, then reinsert the spring bar using the same tool. Verify that the bar is securely fixed.

All straps with a 23mm lug width are compatible with the Oris Aquis 01 733 7789 4150-07 8 23 04PEB. The Milano Straps catalogue features verified articles in this measurement: alligator leather, shell cordovan, vegetable-tanned calf, NATO fabrics, and structured rubber. Each piece is tested to ensure absence of excessive play or premature wear.

Leather strap durability depends on material, tanning method, and frequency of use. Vegetable-tanned calf leather: 3-5 years with regular maintenance. Alligator: 5-7 years. Shell cordovan: 6-8 years. NATO fabrics: 4-6 years. Prolonged exposure to saltwater reduces durability; rinse and dry the strap after immersion. Periodic application of specific balms extends service life.
