Strap for Aquis Big Day Date 45.5 Hammerhead / Rubber

The Oris Aquis Date Relief 01 752 7733 4183-Set RS features a 22mm lug width. This specification is consistent with the 45.50mm diameter case and accommodates a wide range of bespoke leather and technical rubber straps.

Selection depends on intended use case. For formal contexts, genuine alligator in deep black or vegetable-tanned calf in cognac tones are recommended. For regular diving activities, FKM rubber ensures resistance to saltwater and UV exposure. NATO straps in waxed cotton balance practicality and durability in humid environments.

You will require a spring bar removal tool to extract the articulation pins from the lug seats. Position the tool in the groove between the pin and the lug, applying gentle lateral pressure until release. Repeat on both sides. Insert the new strap by aligning the pins with the seats and ensuring complete engagement.

Yes, any strap with a 22mm lug width is compatible. We recommend specialised manufacturers that maintain precise tolerances: excessive clearance between pin and seat causes unintended movement, whilst undersized specifications prevent installation. Always verify technical specifications before purchase.

A quality vegetable-tanned calf strap maintains structural integrity for 3-5 years with daily wear and regular maintenance (gentle cleaning, air drying, occasional conditioning). Frequent saltwater exposure reduces this lifespan considerably. Alligator, owing to greater density, may exceed 7 years. Rubber remains stable indefinitely if protected from extreme thermal fluctuations.
