FAQ
What is the lug width of the Oris Flight Timer 01 635 7568 4061-07 5 21 55?
The Oris Flight Timer 01 635 7568 4061-07 5 21 55 features 21mm lugs. This measurement is specific to the Flight Timer family and requires straps constructed to this width. Measure the lug by laying the strap in the seat: the measurement must pass without lateral tension.
Which strap is best suited for the Oris Flight Timer?
For the Flight Timer 01 635 7568 4061-07 5 21 55, we recommend three options. For elegant daily wear: ebony or mahogany alligator with deployante. For cold season: vegetable-tanned calf leather in natural or cognac, which develops visible patina. For tropical climates or frequent flying: black or brown FKM rubber with smooth texture, which ensures grip in moisture.
How do you change the strap on the Oris Flight Timer 01 635 7568 4061-07 5 21 55?
The Flight Timer has well-designed lugs that facilitate quick strap changes. Use a small flat-lever tool (spring bar tool) or your fingers, applying gentle pressure on the internal spring of the lug: the strap disengages in seconds. Insert the new strap by aligning the end with the seat, then close by gently pushing until the spring clicks into place.
What aftermarket strap is compatible with the Oris Flight Timer?

What is the lifespan of a leather strap on the Flight Timer?

FKM rubber resists 4-6 years. Wear concentrates on the wrist zone: Atelier Casati Milano offers regeneration and finishing replacement services to extend longevity.
