Strap for Aquis Big Day Date 45.5 Hammerhead / Bracelet

The lug width of the Oris Aquis 01 752 7733 4183-Set MB is 20mm. This measurement represents the internal distance between the two lugs on the case and is critical for correct installation of any aftermarket strap. A strap with smaller (18mm) or larger (22mm) lug width would result in instability, mechanical stress on the lugs, and risk of case damage. Always verify that your supplier explicitly certifies compatibility with 20mm.

The Oris Aquis 01 752 7733 4183-Set MB, being a 500-metre diver with substantial proportions (45.50mm diameter), pairs ideally with thick leather straps (alligator or vegetable-tanned calf at 2.0-2.4mm) or cotton-nylon NATO straps. Natural-grain alligator creates aesthetic contrast with the satin-brushed steel case, whilst smooth calf develops visible historical patina over time. For active underwater use, FKM rubber is the supreme technical option: waterproof, salt-resistant, oil-resistant, and non-absorbent.

The strap of the Oris Aquis 01 752 7733 4183-Set MB is replaced by removing the spring bars from the lugs. Recommended procedure: 1) Position the watch case-down on a soft cloth; 2) Use a dedicated spring bar tool to gently compress the bar; 3) Extract one end of the bar from the lug hole; 4) Repeat on the opposite lug. Your new strap must have a certified 20mm lug width. If uncertain, entrust the operation to a professional to avoid damaging the lug holes.

Yes, any strap with 20mm lug width is compatible with the Oris Aquis 01 752 7733 4183-Set MB, regardless of material (leather, NATO, rubber, etc.). Bespoke artisan straps offer superior build quality compared to original replacements: they allow you to select leather type (alligator, calf, shell cordovan), tanning method (vegetable, chrome), colour, and buckle or deployant finishing. Ensure your strap is equipped with standard spring bars for universal compatibility with the 20mm lug width.

The lifespan of a leather strap depends on tanning method and usage. Vegetable-tanned leather: 4-6 years with moderate daily wear; develops visible and historically interesting patina. Chrome-tanned leather: 5-8 years, minimal patina development, greater water resistance. FKM rubber: 8-10 years, particularly resistant if not exposed to prolonged UV rays. Factors reducing lifespan: frequent diving (saltwater accelerates degradation), intense body perspiration, direct sun exposure. A bespoke artisan strap in vegetable-tanned leather, with regular care (drying after immersion, natural balm application), easily achieves 7-8 years of aesthetic and functional use.
