The Oris Divers 65 01 733 7771 3158-07 8 19 15 is a contemporary interpretation of 1960s diving watch design, combining bronze and steel in a 38mm case. It features the automatic Oris 733 caliber with hours, minutes, seconds, and date, along with a domed sapphire crystal and unidirectional bezel. Water-resistant to 300 meters, this model has a 19mm lug width, an uncommon specification requiring careful aftermarket strap selection.

Frequently asked questions

What is the lug width of the Oris Divers 65 01 733 7771 3158-07 8 19 15?

The lug width of this model is 19 millimetres. This is a non-standard measurement in the contemporary market, requiring bespoke strap solutions. Measurement is performed using a digital calliper positioned between the two lugs of the case, at the point where the strap attaches.

What is the best strap choice for the Oris Divers 65?

The choice depends on intended use and aesthetic preference. Alligator leather with vegetable tanning represents the most sophisticated and durable solution, enhancing the natural patina of the bronze case. Vegetable-tanned calf leather creates visual synchronisation with the ageing of the case. Vulcanised rubber is ideal for sporty and daily wear, whilst NATO fabric offers versatility and convenience in strap rotation.

How do you change the strap on the Oris Divers 65?

The strap is secured to the case via spring bars that pass through the lugs. To remove it, you require a spring bar tool: an instrument that compresses the internal spring of the bar, freeing it from the lugs. Position the tool in one of the two terminal slots of the bar, push towards the centre to compress the spring, and slide the bar outward. Repeat for the opposite side. Installation of a new strap follows the reverse procedure.

Is an 18mm or 20mm aftermarket strap compatible with the Oris Divers 65 01 733 7771 3158-07 8 19 15?

No. The 19mm lug width is a precise measurement with no tolerance for variation. An 18mm or 20mm strap will not adhere correctly to the lugs, creating gaps or placing stress on the case, compromising both aesthetics and structural longevity. It is essential to verify 19mm compatibility before purchase.

What is the average lifespan of a leather strap for this watch?

The lifespan of a quality bespoke leather strap ranges from 3 to 5 years with moderate daily use. Alligator and vegetable-tanned calf leather develop a natural patina that improves over time, slowing perceived ageing. Prolonged exposure to humidity, direct heat and intense sunlight reduces lifespan. Periodic maintenance with natural oils and rotation with alternative straps significantly extends the product's service life.
