Strap for Oris Aquis 01 733 7731 4194

The lug width of the Oris Aquis 01 733 7731 4194 is 19 millimetres. This measurement, taken between the horizontal spring bars that traverse the lugs, is a standard specification for 37mm dive watches and ensures harmonious proportions and structural stability. To verify aftermarket strap compatibility, always measure the free space between the pins directly: it must be precisely 19mm.

Strap selection depends on intended usage. For versatile elegance, we recommend vegetable-tanned leather (black or tan), which develops a natural patina and resists marine humidity. For frequent diving, a synthetic NATO strap ensures rapid drying and absolute reliability. If you use the watch as a professional tool watch, vulcanised black rubber is the choice of professional divers: maximum wet grip, zero maintenance, absolute durability.

Strap replacement requires a specialised tool called a spring bar tool. Remove the old strap by gently pushing inward the elastic pins at the strap ends, then extract the strap. To install the new one, position the pin in the lug seat, push slightly inward and allow the pin to lock automatically into the hole. Ensure both pins are perfectly seated before wearing the watch. With 19mm width, the procedure is straightforward and requires no technical expertise.

Absolutely. Provided the strap is specifically engineered for 19mm lugs, it is entirely compatible and functional. Certified 19mm artisanal straps guarantee the same structural reliability as Oris original straps, often with superior materials (vegetable-tanned leather, solid steel stitching) and customisation options impossible with standard products.

A quality leather strap (vegetable-tanned, 3-4mm thickness) maintains structural functionality for 3-5 years with daily use and routine maintenance. Salt-water exposure accelerates ageing, but the resulting patina is aesthetic. If frequently immersed in saltwater, lifespan may reduce to 18-24 months. To extend life, dry the strap after each saltwater exposure and occasionally apply conditioning treatments specific to marine leathers.
