Strap for Oris Flight Timer 01 674 7583 4084

The lug width of the Oris Flight Timer 01 674 7583 4084 is 22 millimetres. This measurement is the distance between the two spring bar pins on the case lugs and represents the standard construction specification for this model. When ordering an aftermarket strap, ensure it is specified for 22mm compatibility to guarantee correct mechanical attachment without play or forcing.

The Flight Timer expresses itself fully with straps in vegetable-tanned calf or alligator in dark tones (Havana, chocolate brown, black). A military green or taupe NATO amplifies its aviation heritage and enables rapid changes without tools. For intensive use and humid environments, an FKM rubber strap in grey or black maintains the instrumental aesthetic whilst guaranteeing superior durability. Your choice depends on the balance desired between formal elegance (vegetable-tanned leather) and operational practicality (NATO or rubber).

The change requires a specific tool called a spring bar tool, a thin lever that allows you to compress the spring-loaded pins (spring bars) that lock the strap to the lugs. Position the tool in the small lateral slot of one spring bar, compress the pin towards the case centre, then slide the old strap end out of its seat. Repeat on the other side. Insert the new strap ends into the lugs, compress the pins and verify they are securely locked. If you are inexperienced, entrust the task to a professional watchmaker.

Yes, provided it is specifically designed for 22mm lug width. Milano Straps catalogues a complete selection of aftermarket straps in calf, alligator, NATO and rubber compatible with this specification. Always verify that the product clearly indicates 22mm compatibility; a generically 'universal' strap may not fit correctly. Custom bespoke straps can be commissioned following technical consultation to ensure perfect adaptation.

A well-maintained vegetable-tanned calf strap lasts on average 3–5 years of regular use, developing natural patina over time. Longevity depends on intensity of use, exposure to direct sunlight, humidity and maintenance. Vegetable-tanned alligator tends to last longer (5–7 years) thanks to the structure of the reptile leather. Expose the strap to dry air periodically, avoid prolonged contact with water and direct heat. When the leather begins to crack or lose flexibility, it is time to replace the strap with a new one in the same 22mm specification.
