Frequently asked questions
What is the lug width of the Oris Divers 65 01 733 7720 4055-07 5 21 26FC?
The lug width is 21 millimetres. This is measured from the inside edge to the inside edge of the lug thickness, excluding the spring bar lever. This dimension requires dedicated straps and is not compatible with standard 20 or 22 millimetre straps.
Which strap material is recommended for the Divers 65?
The Divers 65 pairs beautifully with multiple materials: dark brown or pearl grey alligator for vintage elegance, vegetable-tanned calf for daily practicality, dense cotton NATO for sporting versatility, and natural rubber or Tropic for authentic diving use. Your choice depends on intended wear and aesthetic preference.
How do I change the strap on this watch?
Changing the lug on the Divers 65 requires a 21 millimetre spring bar. Place the watch on a soft cushion, slide the spring bar lever inwards with an appropriate tool until the click release occurs, remove the old lug, insert the new strap, and repeat the process. We recommend having this performed by a certified watchmaker if you lack experience.
Is a 21mm aftermarket strap compatible with this watch?
Yes, any strap with a 21 millimetre lug width is compatible. However, we recommend verifying that the attachment tubes are in brushed or polished stainless steel, consistent with the case finish, and that the spring bar is of Swiss quality. Milanostraps.it offers a specialised collection of handcrafted 21mm straps.
How long does a leather strap last on the Divers 65?
Durability depends on material and usage. A quality alligator or calf, worn four days weekly, typically lasts three to four years before requiring repairs. Rubber and NATO last longer due to reduced wear. Vegetable tanning develops authentic patina—this is not deterioration, but aesthetic evolution.
