Strap for Aquis Date 36.5 Stainless Steel / White / Rubber

The lug width (distance between the attachment points) of the Oris Aquis 01 733 7731 4151-07 4 18 63FC is 18mm. To verify, place a ruler perpendicular to the case between the two lugs, excluding the lugs themselves from measurement. This dimension is standardised across all compatible straps available on the market.

Selection depends on primary use. For formal settings: black alligator or dark tannin-dyed calf with stainless steel deployante. For water sports: NATO in ballistic nylon or vulcanised rubber strap with high grip. For daily versatility: cognac brown calf with leather keeper. Milano Straps curates a selection of 18mm options for every aesthetic and functional requirement.

The Aquis uses standard 18mm spring bars. Proceed as follows: remove the previous strap by inserting a strap removal tool into the lateral grooves of the lugs, applying gentle pressure to compress the internal spring. Align the new strap ends with the spring bars and release. Avoid abrupt pulling that could damage the case. In case of uncertainty, rely on professional replacement service.

Any strap with an 18mm lug width is compatible with this model. Milano Straps offers straps in full grain leather, genuine alligator, shell cordovan, NATO textiles, and vulcanised rubber, all fitted with stainless steel spring bars and hardware. Always verify that the lug width exactly matches 18mm to ensure precise fit and absence of play.

Longevity depends on material and usage. Vegetable-tanned calf with regular maintenance (hygiene, protection from prolonged salt water exposure) guarantees 18–24 months of daily wear. Alligator, being more resistant, reaches 2–3 years. Shell cordovan, owing to fibre density, exceeds 3 years. Vulcanised rubber lasts 3–5 years in marine environments. Replacement is recommended when visible cracks appear in the material or buckle elasticity is lost.
