Strap for Divers Sixty-Five 40 Chronograph Stainless Steel / Silver - Green / Strap

The lug width of the Oris Divers 65 is 20 mm, which is the horizontal distance between the two lateral lugs of the case where the strap attaches. This measurement is critical for ensuring compatibility with aftermarket straps. A 20 mm strap will fit perfectly, providing balanced wrist wear without excessive rigidity. On milanostraps.it, you will find a comprehensive selection of straps in this size, specifically tested for the Divers 65.

The choice depends on your usage context. For formal elegance, we recommend alligator in grey-blue or black with fine graining, which creates a fascinating contrast with the satin-finished case. For a luxury-sustainable approach, vegetable-tanned calf leather ages beautifully over time. For the watch's sporting vocation, a thick leather strap (strap leather) with a coarse grain enhances the instrumental appeal. For humid climates or frequent diving, FKM rubber or silicone offers unparalleled practicality and instant drying. A cotton NATO strap is ideal for daily rotation.

The procedure requires extracting the spring bars that connect the strap to the case lugs. Obtain a spring bar tool (a specialised watchmaking instrument), or alternatively use a pen or small flathead screwdriver. Insert the tool from inside the strap, press the small elastic pin downward, and the bar will slide out. Repeat on the other side. Reverse the procedure to mount the new strap. If you lack confidence, professional watchmakers and the Casati Milano atelier offer this replacement service quickly and without excessive labour charges.

Yes, absolutely. Since the lug width is 20 mm, any quality strap manufactured for this size will fit perfectly. On milanostraps.it you will find artisanal straps in leather (alligator, calf, shell cordovan), NATO, and technical rubber, all compatible and ready for shipment. The real difference between an OEM (original Oris) strap and a quality aftermarket strap lies in construction, materials, and aesthetic patina over time: a good artisanal strap often surpasses the original in longevity and charm.

The lifespan of a leather strap depends on leather quality, frequency of use, ambient humidity, and care. A vegetable-tanned calf strap worn daily in temperate climate can last 3–5 years before requiring replacement. Artisanal shell cordovan, due to denser fibres, can last 7–10 years. Constant exposure to moisture, perspiration, and water significantly reduces lifespan (1–2 years). To extend strap life, we recommend: rapid drying after water contact, application of nourishing creams every 6–8 months, and rotation with other straps (NATO or rubber) during summer months.
