Strap for Aquis Date 36.5 Stainless Steel / Pink MOP / Bracelet

The lug width of the Oris Aquis 01 733 7770 4158-07 8 18 05P is 20mm. This measurement represents the internal distance between the integrated lugs of the case where the spring bars attach. It is essential to verify this dimension with a digital calliper before ordering a replacement strap, as even minimal tolerance deviations compromise strap stability and spring bar functionality.

For the Aquis 36.5mm we recommend three primary materials: anilina alligator with vegetable tanning for formal elegance, Italian vegetable-tanned calf for natural aesthetic continuity, or vulcanised elastomer and NATO for water resistance in sporting contexts. Choice depends on primary usage: aquatic environments suggest rubber or NATO; formal daily wear privileges superior leather quality. The brushed stainless steel case pairs particularly well with cognac or dark grey tones.

Replacement requires a professional spring bar tool: insert the lever gently into the lug opening, compress the spring bar until the retention ball disengages, remove the worn strap. Insert the new strap aligning its hole to the spring bar pin, press until you hear the repositioning click. If you lack the specialist tools, the Casati Milano workshop performs replacement by appointment, guaranteeing zero risk to the case.

Yes, any strap with a 20mm lug width is theoretically compatible. However, build quality varies significantly: Milano Straps artisanal straps guarantee millimetre-precise tolerances, natural leather linings, and finishes that enhance the Aquis architecture. An economy strap, whilst compatible, may cause micro-movements of the keeper or colour transfer from leather in contact with stainless steel.

Longevity depends on material and usage patterns. Superior quality alligator or calf with vegetable tanning, worn daily in normal environments, achieves 4-6 years of structural life. Natural patina evolves over time, increasing aesthetic character. NATO or elastomer resists 3-5 years under frequent aquatic exposure. Lifespan extends significantly by reducing direct exposure to extreme sun and humidity. The natural leather lining absorbs moisture: periodic cleaning with a soft cloth preserves strap structural integrity.
