Strap for Oris Divers 01 643 7636 7191

The Oris Divers 01 643 7636 7191 features a lug width of 24 millimetres. This standard measurement represents the distance between the lugs of the case where the spring bars are positioned to support the strap. A correctly fitted aftermarket strap for this model must have an exact 24mm lug width to ensure a gap-free fit and uniform tension distribution across the case.

The choice depends on intended use and aesthetic preferences. For harmony with titanium, a Tuscan leather with vegetable tanning in military green or dark brown represents the most elegant solution and develops a natural patina over time. For formal environments, a Loire alligator in brown or black offers a consistent grain and smooth surface that emphasises the geometric purity of the case. For everyday versatility, a NATO strap in heavyweight cotton or an FKM elastomer provides practicality and durability. The titanium case accepts all these materials without chromatic conflict.

Strap replacement is a straightforward operation requiring a spring bar removal tool (available in basic watchmaking kits) or a small flat screwdriver. Position the watch with one lug facing upwards, locate the small hole on the upper and lower portions of the lug. Insert the tool into the hole, apply gentle downward pressure to compress the internal spring, then pull the old strap outward. Repeat on the opposite side. To install the new strap, align the strap holes with the spring bar pins and press until you hear a click. Verify the strap is securely attached before wearing the watch.

Yes, any strap with a 24mm lug width is perfectly compatible with your Oris Divers. Artisanal straps in Tuscan leather, alligator, calf leather or straps in FKM rubber and NATO fabric manufactured specifically for this lug width fit perfectly without any structural compromise. Compatibility is not limited to original Oris straps: specialised manufacturers such as Milano Straps offer curated alternatives that often exceed the construction standards of generic straps, ensuring superior material quality and stitching.

The lifespan of a leather strap depends on use frequency, wearing habits and tanning quality. A high-quality Tuscan leather with vegetable tanning maintains elasticity and durability for 5–8 years of moderate daily wear. Vegetable tanning, unlike industrial chrome tanning, ages in a controlled manner, developing an increasingly rich patina. To extend longevity, avoid prolonged exposure to extreme humidity (leather naturally absorbs moisture), occasionally wash with lukewarm water and neutral soap, and air dry away from direct sunlight. Loire alligator, thanks to its more resistant texture, can last 7–10 years under standard use conditions. FKM rubber straps typically last 3–5 years before showing signs of brittleness and loss of elasticity.
