Frequently asked questions

What is the lug width of the Oris Rectangular 01 561 7656 4034-07 8 17 82?

The Rectangular features a lug width of 17 mm, a precise measurement requiring bespoke straps. It is not a standard mass-market dimension. You can verify this by placing a digital calliper between the two metal lugs inside the case.

What is the best strap for the Oris Rectangular 01 561 7656 4034-07 8 17 82?

We recommend a vegetable-tanned leather strap for daily elegant wear, alligator for formal occasions, and NATO for sportive versatility. Your choice depends on your watch rotation and personal aesthetic. Vegetable-tanned leather develops a patina that synchronises perfectly with the case's vintage-modern character.

How do I change the strap on the Rectangular 01 561 7656 4034-07 8 17 82?

The Rectangular employs a standard spring bar system: insert a strap change tool or fine pin into the small slot beneath the spring bar, press gently downward to release it, then slide the bar out of the lugs. Proceed with care to avoid scratching the case. Atelier Casati Milano offers this service in-house for those preferring professional handling.

Can I use an aftermarket compatible strap on the Rectangular 01 561 7656 4034-07 8 17 82?

Yes, but it must be specifically 17 mm lug width. Many aftermarket straps come only in 18, 20, or 22 mm. MilanoStraps offers a complete collection of 17 mm straps in leather, NATO, and rubber, all compatible and ready to ship.

How long does a leather strap last on the Rectangular 01 561 7656 4034-07 8 17 82?

A quality vegetable-tanned leather strap has an average lifespan of 3–5 years with daily wear, varying based on climate, perspiration, and maintenance. Vegetable leather develops a fascinating patina but wears naturally. Rotating multiple straps extends overall longevity and protects your initial investment.
